[appengine-java] Object visibility between threads (running requests)
Hi I have created an application that works fin in the eclipse app engine development environment but when I deploy it live I get some problems. My application depends on two request coming in simultaneously from two different browsers, both requests (threads) gets a map from servlet context then both gets an object from the map with the same key, i.e. the same object super.toString says so and .hashCode says so. The first thread updates the object and then waits for the other thread to signal that it has read the change and done some operations. But the second thread never sees the change made by the first thread, the result of this is thet the first thread hanging for 30 seconds and the throws an exception. If I let the first thread return the second thread sees the change, but then it is too late. The project is up and running but not working at http://sendnow4.appspot.com and the code (not the latest but a working version) can be found at http://code.google.com/p/sendnow/ Best regards //Samuel -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Help with local testing of Task Queue
Hi Amar, No sure, maybe you did find the solution already yourself. I think you get a 405 because your servlet (?) only supports GET request. At least that was the problem I had. In my case the solution was by simply setting the method to GET when scheduling a new task: QueueFactory.getDefaultQueue().add(TaskOptions.Builder.withUrl(/ updateFriends).param(userId, +user.getId()).method(Method.GET)); regards, Nils On Apr 25, 11:13 pm, Amar Z amarzumkhaw...@gmail.com wrote: Hi, I am developing a new application and need help utilizing task queues.

Yes, there is a more detailed explanation of JDO under Java/Storing Data. But it does not deal with the Guestbook example, which is a very nice little step-by-step introduction for beginners. OK, I can use cache: to get the old version, but I had hoped that there was a more official old tutorial version. Of course, it would also be interesting to know if GAE is moving away from JDO, and if that is the reason for changing the tutorial.

[appengine-java] Setting Namespace for an entire Request
Hi! I'm trying to use the Namespace-API to build a multi-tenant app. Therefore i have defined a filter that sets the Namespace for each request regarding to the User making the request. However, if there's a new Request before the current request finishes its datastore-operation, the namespace would be overwritten by the new request and the current operation would have an incorrect namespace. I could also set the namespace before each datastore operation, but the problem would be the same.If another request overwrites the namespace before the operation is finished, the data in the database will be messed. Is there a way to set the namespace for an entire request? Or should i try to build some kind of Mutex around the NamespaceManager?

[appengine-java] Re: old tutorials still available?
Yeah, I can see your point. I've begun to like the datastore query class better for queries, but for putting it into object form JDO query class seems to be easier. Although, the datastore query class seems a bit more flexible and easier to query with filters and sort. I think JDO's design is a bit more textual in the query and datastore query is more static constants, which is a bit easier for me to use. It would be nice if you could have a utility class to assemble the entity into the object/class like JDO when using the datastore query.

Re: [appengine-java] Re: Backends.xml ERROR when deploying
Backends are definitely ready for Java, but it seems that there are some mistakes in the documentation. We'll get those fixed right away. The correct link to the backends API javadoc is: http://code.google.com/appengine/docs/java/com/google/api/backends/package-summary.html And the sample backends.xml file should look like this: backends backend name=memdb classb8/class instances5/instances /backend backend name=worker options fail-fasttrue/fail-fast /options/ backend backend name=cmdline namecmdline/name options dynamictrue/dynamic /options/ backend /backends JT, please read through this: http://code.google.com/appengine/docs/java/backends/ Backends are essential special App Engine instances that can run work beyond the usual request deadlines and can maintain state in memory. You can think of them as stateful backends, which should be a less ambiguous name.

Re: [appengine-java] Re: After upgrade to GAE SDK 1.5.0 - Cache is not working
Sorry about this, folks. We'll get a new SDK built that includes the right
appengine-jsr107cache.jar file. In the mean time you can use javax.cache or
a previous version of appengine-jsr107cache.jar (there were no changes to it
in 1.5.0), but I would strongly encourage everyone to move from javax.cache
to net.sf.jsr107cache once this problem is fixed. We are no longer making
bugfixes to javax.cache and will at some point remove it from the SDK.

You might want to consider denormalizing that table by one field?
That is, create a new entity holding a foreign key relation and the
field of interest,
and create an index for that query equality.
Reads are fast, and updates are slower so creating new entities for
that data
rather than updating an increasingly large entity (the entity with a
list) might be a good approach.

[appengine-java] questions about backends with Cron and Task Queues
I'm very excited to start using backends with my GAE project. Because of the past 30sec restrictions, I heavily divided up the big processing tasks I was doing (refreshing RSS and ATOM feeds) into a lot of tasks that I put into task queues. These refresh jobs are all started with a few Cron jobs. I want to move processing over to a backend but am wondering how to address these jobs to that backend. If I try to call the urls on the backend directly, I get errors because task queues and cron will only run jobs that begin with '/' It would be nice if I could specify a backend in the Cron XML or as a parameter in task queues TaskOptions.Builder.withBackend(mother).withUrl(...

[appengine-java] Adding the Ability to Set a Beta or Other Version of an Application To A Domain
At Google IO, one of the members of the audience asked if the App Engine team was considering adding the ability to map a subdomain to a specific version in an App Engine App, other than the default version. Currently, you can map a domain only to the default version. However, it would be nice to be able to map a second domain to another version in the Version Administrative panel. For instance: default - www.example.com - Mapped to version 5 beta - beta.example.com - Mapped to the new version 7 Then in the Version panel, users would select both a default version as well as a beta version. Since a picture speaks a thousand words, I've attached an example of what this feature might look like in the Google App Engine Version Panel: http://commondatastorage.googleapis.com/jem/forums/AppEngineVersions.png There may be a way to add more subdomains to specific versions to support more depth in managing versions, but I think this would be a great start.

When I manually test an alternate URL using the loopback ip,http://127.0.0.1/tasks/kmlnotification, I can access the URL from the web browser with no error. So the /tasks/kmlnotification URL is accessible using 127.0.0.1 though not on the 0.0.0.0 IP address used by the app engine. Is 0.0.0.0 the appropriate IP address for web hook invocation? I am using the default queue and have no role restrictions in my configurations.

[appengine-java] UserService.getCurrentUser() returning null sometimes
Hi, I have a GWT application. For every RPC made, I do UserService.getCurrentUser() on the server, and then go ahead with the business logic. Sometimes, this call is returning null.

Re: [google-appengine] Where I pulled the 70X from AND How the new pricing could be cheaper for you!
Brandon, thanks for the detailed analysis. I too had almost exactly the same thoughts regarding CPU vs Instance billing. Lets wait for the new scheduler to go live before finally deciding on the path ahead. Only hope that once it (the scheduler) stabilizes, we don't go through the entire cycle again if when Google decided to change things again in the future or at-least the transition wouldn't be as drastic!! Sam On Fri, May 13, 2011 at 10:51 AM, Brandon Wirtz drak...@digerat.com wrote: I know that my use case for GAE is non-typical. And as I mentioned before I’ll likely have to port my code to a different language under the new pricing, but I wanted to share how my use case works, and how yours may differ. When I moved to 1.5 it seems in my app that the sites getting the improvement have the highest MemCache hit ratio. Likely the improvement is a function of something related to that. I also noticed the request time went down the most on those, so probably I'm just seeing the effect of requests on those sites taking 30% less time so each instance serves 30% more people. On one of my apps I saw nearly zero improvements. And it is the one that worries me the most pricing wise. It cruises along at 60-75 instances 24/7 but only use 10 CPU hours a day CPU Time $0.10/ CPU hour [image: Description: 8%] 8% 9.95 of 127.50 CPU hours $0.35 / $12.10 Because of the free quota that is 35 cents a day for the CPU But if there was no free quota, or we were really big so the free quota was not factored. That would be 10x $0.10 or a $1 a day But 60 instances 24 hours at 5 cents per is $72 so 72X the price (before any scheduler efficiencies) This is where I got the 70X I quoted before. I have another app that runs at 9 instances (after moving to 1.5) that uses 5 CPU Hours a day CPU Time $0.10/ CPU hour [image: Description: 1%] 1% 5.00 of 406.50 CPU hours $0.00 / $40.00 9x 24x.05 = $10 (and some pennies) vs 50 cents on the old model. 20x before any scheduler efficiencies I believe my use is the way it is because the really short logic of my code goes like this. User: I need a file App: I have that in memcache it’s popular right now. Sending …. …. 50ms later… User:Thanks! (Instance time 75ms CPU time 25ms) OR…. User:I need a file APP: I don’t have that in memcache let me go get that for you … 110ms later… DataStore: Here is that file you asked for. App: Great I’ll pass it to the user … … 50ms later User Thanks. (Instance time 200ms CPU time 40ms) OR… (and this one kills me) User:I need a big file APP: I don’t have that in memcache let me go get that for you … 110ms later… DataStore: Here is that file you asked for its big. App: Yeah I know and this user is on dial up. They Suck … … … … … 1500ms later User Thanks. What took so long. (Instance time 2000ms CPU time 40ms) And In all three of these scenarios what I’m really paying for if I get billed by instances is the waiting to send stuff to the user, and possibly read it out of GQL. None of this uses the “Python” bits for anything useful. If on the other hand I was folding proteins or searching for extraterrestrials my Instance hours and my CPU hours would be far less disparate. In fact because instance hours are cheaper than CPU Hours if you can keep your instance at better than 50% load at all times you will in fact save money. *SO….*Check this out, the old price per CPU hour was 10 cents, but a Reserved Instance is 5 cents. So if you can figure out how to not wait on the dumb user and his 56k connection, and not sit idle while waiting on some value to be returned from the depths of where ever Google stores your data and all the lost socks from my laundry, then you can actually save money on the new pricing. It’s my horribly inefficient use of the time that I’m waiting on the user that gets me to 70x. If this were PHP I’d have a do while that folded proteins while I waited for my user to receive their bits, but I can’t do that. Google on the other hand could likely make my apps much more efficient if there were a request handler that said “This dude is asking for a thing” and I’d say “put them on hold I’ll get you the file, Got it, here it is” and it would then say “what do you want me to do with this? Read it to them?” and I’d say “Yep”, “you suck why do I have to do that” , “Because you are the edge cache and that is your job”. And I think some days this works, (so do cache control headers and the edge caching such that when two people ask for the same exact thing only 1 hits my APP) and other days it doesn’t work so much. And I don’t really know why cause I can’t see the moving parts, only part of what is on each side of a row of magic black boxes. -- You received this message because you are subscribed to the Google Groups

[google-appengine] Re: MultiThreaded Setting cuts required instances by 1/4th for my app
Some pricing changes are a bit weird, like sending emails. Google made Gmail. And now I can send more free emails with my private account than with my app? Was old quota really so bad? Now I will have to pay even to have an option to send out reasonable amount of password remainder emails... or activation emails. And it's one thing that can be abused by someone that wants to raise my bills or just block this function if it hits the limit. Google should avoid any changes that make you wonder maybe I should integrate some external tool/service with my app. That's just opposite to what GAE stands for - it should be easy, without any hassle, without dividing your app, using hacks and weird solutions. I want whole package in one place - but I will use those workarounds if they are really cheaper.

[google-appengine] Re: Backends clarifications
Ah that's great news then, I didn't realize that. Greg: Thanks for the link, I was a bit misunderstood and didn't see it in the App Engine Samples. One thing that's intrigued me about the reserved backend, and it mentions in the documentation, is to keep track of game states. I was hoping someone could tell me if this setup would make sense: if I need to update possibly hundreds of game states, and by update I mean sending out actual updates via the Channel API, I thought I could do this by two separate instances. One of which holds the data(there isn't much data to keep track of, 128MB may be sufficient), the other operates on a while loop that only exits when all games have completed and runs every second or every other second using time.sleep(1000) or 2000. It sends out updates to each client in each game that requires updates, and gets the data from the other backend instance. Then it would sleep until the next iteration. Is this a sensible use of backends or is this actually more suited to tasks? I was originally using tasks that enqueue a new task each following second to accomplish this. Which one would be better and why?

Re: [google-appengine] 1.5 improvements Make me less scared of Pricing
On Fri, May 13, 2011 at 3:29 AM, Brandon Wirtz drak...@digerat.com wrote: I am slow to upgrade because I like to know that things won’t explode, but this graph shows how 1.5 reduced the number of instances I need compared to 1.4 (maybe 1.3) that I was running. Usually I version thing so you can’t see the graph before. I don't think that's how versioning works. Google updates their infrastructure independently of which SDK you have installed on your laptop. You can see this effect as people report fresh bugs in their deployed apps without having redeployed. So delaying updating your SDK is not the conservative strategy. To be conservative, you should install the preview SDK as soon as it is released and run your tests locally. The production machines seem to be updated with the preview SDK release, which is about 2-7 days before the final SDK is announced. So why the change in number of instances? I don't think you can read too much into it. Under the current pricing scheme Google's incentive is to optimise the scheduler because they pay for any inefficiencies. They can't run every machine at 100% utilisation all the time. It may be the case that the machines your app happened to be deployed to last week had spare capacity and Google calculated that it was more efficient to leave more of your instances relatively idle in memory that to stop and restart them. This week, perhaps some collocated apps had a traffic spike and Google calculated that it would be more efficient to allocate some of those instance slots to someone else. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: 1.5 improvements Make me less scared of Pricing
No doubt when I moved to HR my instances basically quit dying. With M/ S an idle instance would be killed off quickly, with HR they hang around for days. At the time I was very happy about this. This was a complaint in the past (how fast Google killed idle instances.) But now I think the reverse will happen and people will want them terminated as quickly as possible. On May 13, 6:40 am, Greg g.fawc...@gmail.com wrote: I'm not seeing any significant reduction in instances either.

[google-appengine] Re: 1.5 improvements Make me less scared of Pricing
Currently all my python scripts use the script-or-module mechanism as
recommended by the docs
application = webapp.WSGIApplication([('/somepage',
SomeHandler), ('/anotherpage', AnotherHandler)], debug=True)
# GAE will look for a main() with no args and, if found, caches this script
# so we supply one to make the requests more efficient
def main():
run_wsgi_app(application)
# How a file can be both a script and an imprtable module...
if __name__ == __main__:
main()
I'm wondering if I rename that function to not be main, hence making the
page just a script and no longer an importable module, will that effectively
kill the instance after the script runs (my load time is minimal - most of
my pages simply do datatore-query - JSON or the reverse) and so minimise my
instance hours ??
Would it be possible to add something to the GAE API's so that an instance
can suggest how long it would like to hang around for, or an ability to
explicitly request to kill itself ?

[google-appengine] Re: Is App Engine suddenly becoming more expensive???
I am very unclear, even after reading this thread and elsewhere, what impact the scheduler will have on reducing my instances for my python based app. I don't have a particularly intense app - log some data, analyze some data, push some data into spreadsheets. .62 CPU/hrs/day6 instances @ 30MB each. I can't imagine what I would code to make them go away. Or do I have to port to Java? I'm paying $50/yr, which is really cheap. However, 5 instances (1 free, right) @ .05/hr = $180/month just for the instances. 6 instances @ 30MB each$2160/yr... An AWS Micro instance has 613MB of ram and can burst to 2 ECU's and costs $115/yr The $9/mo for single instance looks a lot like AWS pricing (from a $ standpoint) but then you must give us the tools to make things multi- task. I must think that my app uses less resources than something cranking away multi-threaded in a single instance...

Re: [google-appengine] New pricing and accessing external Services
Hi Maximilian, Thanks for the feedback. We're hoping that the different offerings available will allow you to architect around this. For instance - you can use the pull queues feature to push tasks to background servers, and use those to do synchronous URLfetches. Alternatively, another solution may be an RPC/callback based infrastructure (it sounds like you are in control of the remote services). One of the sustainability issues with the current billing model is that memory usage constitutes a non-trivial cost. While it's true that instances will sit idle and not cost CPU, they consume memory just by way of existing. Just out of curiosity, are you using Java or Python?

The internal Applications are critical for our company but previously GAE4B as not sustainable for us - see https://groups.google.com/group/google-appengine/msg/00ad4ae42b320ebd . The new pricing model addresses most of my concerns regarding GAE4B. Until now we have paying one or two dozen US$ for running highly critical business applications on GAE and frankly that was too cheap. I hope it will not get too expensive in near future. We spend a LOT of time in urlfetch. Connecting to S3, (PDF generation|OCR|SOLR|SQL|Authentication|etc) as a Webservice. So our instances spend most time sitting there consuming memory and no CPU and waiting for some external Service to do something. This waiting was up to now certainly to cheap - more or less fro free. But seeing it being billed by the instance hour somewhat worries me. When running big map reduce jobs currently we see 40-60 instances coming online for a few minutes, costing us nearly nothing because they consume barely CPU - too cheap. The new pricing model would make such runs probably too expensive. I hope in instance parallelism will help here but I'm skeptical. Also it was nice to be able to host experimental/pro bono applications which received only a few hundred requests per hour at a very competitive price. It would be a shame if GAE would drop out of that model. I understand for the Premium subscription this is still possible, but for 9U$/month/app it will not viable for most people to run half a dozen tiny apps on GAE. Perhaps this is intentional, perhaps not. Still, I'm happy for GAE to be moving in the direction of becoming a real business. I'm also impressed by Google beeing open about the fact that this actually IS a price increase. --md -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Just FYI, DateProperty, TimeProperty and DatetimeProperty all store the same type in the datastore: a datetime representation. The difference is that the first two are stored incomplete (on DateProperty, time will be 00:00 00:00, on TimeProperty, date will be 1970-01-01), and that's what you see in the datastore. It's hard to justify using DateProperty or TimeProperty since the storage space used and underlying type are the same, so I end always using DatetimeProperty. -- rodrigo -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] B8 vs B4 vs B2 vs B1 , B8 = B4 ?
Please see the Backends talk from Google IO
(http://www.youtube.com/watch?v=-kepYfCBg6w).
It is mentioned in this talk that a single thread is only able to use
2.4Ghz of cpu. This is why a B4 and B8 appear the to have the same
amount of cpu time in your example. To take full advantage of the cpu
available in a B8, you have to use the java runtime at the moment.
It is important to note that a B8 also has twice the memory that a B4
has. This means you may still want to use a B8 python backend to take
advantage of the 1GB of ram.

Re: [google-appengine] Re: Backends clarifications
This sounds like a excellent use of backends. I believe that there is currently a limitation that a channel created in a frontend (ie, your default version) is not able to be used to send messages from a backend. As noted in the Google IO talk, we are currently working on removing this restriction. For the moment, you could work around this limitation by creating the channel in the backend that you want to send messages from, then pass it back to the frontend/user. On 13 May 2011 02:37, Richard Arrano rickarr...@gmail.com wrote: Ah that's great news then, I didn't realize that. Greg: Thanks for the link, I was a bit misunderstood and didn't see it in the App Engine Samples. One thing that's intrigued me about the reserved backend, and it mentions in the documentation, is to keep track of game states. I was hoping someone could tell me if this setup would make sense: if I need to update possibly hundreds of game states, and by update I mean sending out actual updates via the Channel API, I thought I could do this by two separate instances. One of which holds the data(there isn't much data to keep track of, 128MB may be sufficient), the other operates on a while loop that only exits when all games have completed and runs every second or every other second using time.sleep(1000) or 2000. It sends out updates to each client in each game that requires updates, and gets the data from the other backend instance. Then it would sleep until the next iteration. Is this a sensible use of backends or is this actually more suited to tasks? I was originally using tasks that enqueue a new task each following second to accomplish this. Which one would be better and why?

[google-appengine] Re: Question about dynamic backends
Good question. Here's how this works. For the moment, let's only consider resident backends: 1) Backends are charged for uptime by the minute. 2) Whenever a backend instance goes down, the system will continue to bill for an extra 15 minutes. 3) If a backend comes back up within the 15 minute period after it last shut down, it gets partial credit for the time it would have been charged for. For example, let's say a backend instance starts up and runs for 30 minutes, and then stops. The total charge is 45 minutes. Taking another step, let's say a backend instance starts up and runs for 30 minutes, stops, and then comes back up 10 minutes later and runs for an hour. The total charge is as follows: - 30 minutes for the first uptime interval - 10 minutes of additional time - 60 minutes for the second uptime interval - 15 minutes of additional time Total time elapsed: 115 minutes Total time billied: 115 minutes Thus, you could describe this system as blended intervals, where we never double-charge for uptime, and smooth across periods of downtime that last less than 15 minutes. So the 15-minute charge for startup is a simplified way of explaining things. You can think of it that way, but you're never double-counted for uptime. Dynamic backends work the same way, except that we use active intervals rather than uptime intervals. If your dynamic backend is handling a request, it is considered active. As an example, let's say your dynamic backend was handling requests for 30 minutes, then was idle for 10 minutes, then handled requests for another 60 minutes. The charge would work out exactly as the example above, except that your backend would likely be evicted after about ~2-5 minutes of idle time. So the timeline looks like: - startup - active for 30 minutes - idle for 3 minutes - shutdown - down for 7 minutes - startup - active for 60 minutes - idle for 3 minutes - shutdown Since the period of downtime was less than 15 minutes, the total charge is as if the backend was active for 100 minutes, with an extra 15 minutes appended at the end. The upshot of all this is that the system encourages you to keep your backend instances up and active for long periods, rather than starting and stopping them regularly. If you're doing that, then you probably don't need to use a backend. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Thanks Robert. Keeping field names small is good advice. I like to do that and use an interface for the more readable names outside the DAO in my domain model.

Unless there is some other reason to, I would probably not personally waste the resources to batch and compres the data. If it is about reducing storage cost, you're liable to spend more money in CPU time mapping the data to bundle, compress, and index it than just paying for the storage space of the entities. What you might want to think about, if you're not already, is making sure you use very short kind and property names in the datastore. Storing the property name millions of times can add up, especially if you've got long property names on indexed properties. I've been using the namespace (multitenant) feature in some apps.

OR.(highly unlikely) Do I hope that GAE makes the instances smaller and cheaper when running python so that I can get $.02 per hour instances that are 1 4th the size so they run at 100% cpu instead of 25% cpu? Essentially I'm asking It appears in the new paradigm pricing was optimized for Java, is this the case or is it optimized for GO and Java just gets the benefits right now, or is Python really what GAE was born for and will it come back to being the cost favorite? -Brandon -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Than again: I can do a development / hosting cost trade-off an that's fine with me. An other approach will be using async urlfetch although this will also need some serious reengineering of our client libraries. Callback and Pull-Que approaches will make our apps less robust and harder to understand and debug. In a urlfetch API the dashboard alone can give you a very good indication if a addressed service starts failing. With pull queues you additionally have to monitor the queue sizes and need to have a feeling what can be considered normal. With Callbacks you have to build the monitoring all by yourself. Async programming is much harder to get right ... Just out of curiosity, are you using Java or Python? Python.

[google-appengine] Drop Table equivalent?
I know people have asked variations of this question, and the solution has always been to drop entities 1000 at a time, But have an app that the cleanup code had a misspelling so it never did anything except clean things that didn't exist. Is there a Drop Table equivalent? Or do I really query 1000 and delete over and over. Cause it appears that's going to be like $100 which is fine.. If that is the best solution, but if there is a drop table equivalent that is $5 I'd really like that so that I can use it in my code that would normally get charged the $100 over 6 months . -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: Google App Engine OAuth endpoints throwing 400 in production.
OK I have some new information and questions to add to this discussion: 1 - There is some confusion in the documentation over whether registration is required or not. Both here http://code.google.com/appengine/docs/python/oauth/overview.htmland herehttp://code.google.com/apis/accounts/docs/RegistrationForWebAppsAuto.html, it says registration is optional. Regardless, I have registered my app. 2 - When going through the process of registering your application with Google, you're informed that a certificate is not necessary on Google App Engine, and that the OAuth signature method is HMAC-SHA1. Can anyone confirm that as the case for using the OAuth for Python? 3- Testing this locally doesn't provide much feedback because no matter what you pass, it works. On appspot, it's the opposite problem because there's no information on what failed. I've tried the OAuth Playground, which is great, but wanted to verify that it supports testing OAuth for python. I am using it to test my Request for a Token and it fails, reporting, signature_invalid. The documentation on signature construction is confusing, in some cases it indicates sending a base string to the server that is the request url encoded, and in other places it seems to be saying that you pass the string directly as in: oauth_signature=wOJIO9A2W5mFwDgiDvZbTSMK%2FPY%3D Can anyone clarify? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] What do you want to see answered in Greg's pricing FAQ?
Thanks for the collection of links, very useful. Hacker News isn't the fount of wisdom it once was (if its mythology is to be believed), but here's the money quote from a Hacker News thread: I guess I felt that my implicit feelings on App Engine were something like, Hey hackers! You should totally rewrite your apps for our Google systems that are a lot more efficient than other systems. Yeah, there are some annoying restrictions that you'll have to get used to and are totally a pain for some things. Still, out service is cheap for loads of usage and really cheap even after that so you're spending a little programmer time for no-hassle-scaling and cheaper hosting than anything you can get! However, they've consistently lowered the free usage tier to being a fraction of what it once was, they're now charging a ton more with their instance-hour model compared to the old CPU based model, a bit of the reliability/scaling sheen has worn off as it's had problems, other competitors have been aggressively entering this space, and you still have to alter your apps specifically for their architecture. I'm not saying that App Engine doesn't have value, just that it feels very different. http://news.ycombinator.com/item?id=2533898 saidimu On Thu, May 12, 2011 at 5:46 PM, Vanni Totaro vanni.tot...@gmail.comwrote: Hi Greg, no FAQ from you yet... so in the meanwhile here it is a list of links you (and Ikai, Nick, Justin, etc.) should visit to know what gae users said in the last couple of days about pricing news.

[google-appengine] Re: So Tell Me About GO
If you look at the go docs it looks like it only supports sync ops on urlfetch/datastore/etc. However when one of these ops is started then other goroutines start running. And the goroutines can send messages to each other. So go provides the only language-native async system for gae. Rob Pike claims that this is a good way to think about async operations. There isn't much CPU involved usually, so the restriction to 1 thread is really irrelevant most of the time. However you'd need to be very brave to go for go when we haven't even seen a draft of how they plan to do transactions and channels. Or have we? -- You received this message because you are subscribed to the Google Groups Google App Engine group. To post to this group, send email to google-appengine@googlegroups.com.
