[google-appengine] Re: Querying for N random records on Appengine datastore
I was just thinking this last night when I wasn't at my computer.
Darn you for publishing my good idea first! :)
It doesn't bring the number of queries down to 1, but it does bring
them down to 2, at least on the request side.
Of course, it also means one extra transactions every time a new
entity is created, so I don't know if there's any net savings, but
this does seem like a reasonable way to address the issue at hand.

A possibility is to maintain an index, which is a pickled list of
entity keys, stored as a blob somewhere. You'll need to maintain the
index by adding/removing keys as you add/remove entities. But then,
when you need to make a random choice, just unpickle the list, grab
any five keys from the list, and db.get([keys]).

no, I dont. The way in my first reply is the best I can think off. Not

AppEngine.
A reasonably good solution, is to use a FIFO buffer, when the queue is
empty you get all keys, and shuffle them and add to the queue. then
getting random results is a matter of poping that many keys off the
queue, and fetching them.

Assigning random numbers to entities is guaranteed to be worse. If
you are worried about an entity being deleted and opening a gap in the
sequence, imagine the thousand-fold gaps you will see with random ID
generation (e.g. 1, 10001, 10002, 2, ...).
See below.

If an app needs to support entity deletion, you can still ensure
uniformity by running a periodic cron job to compress the counter
sequence.
nor does it work if you filtering at the same time :(
Correct, in that the distribution is no longer uniform. But this is
also true of the random ID approach. I admit that the random ID
approach seems appealing at first, but when you actually look into it,
you'll find that you are guaranteed that many results will be 3X more
likely than others, or worse. It IS better in the case that you want
to randomize based on time of entity creation, but there are other
ways to deal with this.
I would love it if someone could come up with a good way to do true
random results of an arbitrary query set!!
Note that behind the scenes this generates multiple queries, so
you're
not saving much time.

shifts the work from request time to a background process so your
users don't see the added latency for doing N queries.
Another possible solution would be to fetch keys only for X*N
entities
(where greater X's produce more apparent randomness) then choose
N of
those keys to actually fetch entities.

I currently assign a random number to every kind that I put

This works, however, it only returns 1 record so I need to do N

[google-appengine] Re: urlfetch... Implementing my own cache? Memcache?
Hi Jordisan, I'm working on something very similar, and yes, I do use both memcache and the datastore, to ensure that the cached data lasts as long as I want it to. Memcache, IIUC, is not guaranteed to hold onto your data for as long as you specify. So my code looks like this: on request for data: - Check memcache to see if I have it stored (the identifier is the URL path). This way, oft-requested files are served most quickly. - If not, check the datastore. This way, I don't have to hit the originating site for any non-updated data. - If not, do a URL fetch and grab it, caching it in memcache and datastore. For my purposes, I don't store posts--since they're usually dynamic CGI script requests on the sites I'm using it with, and I don't cache gets that have query strings. Eventually, I'm going to build a management app that will allow me to specify cache time, purge stored data manually, etc., but right now it's set up as described above. -Ben On May 25, 2:49 am, jordisan ram...@gmail.com wrote: Hi.

[google-appengine] Re: push http not allowed?
The AJAX disconnect and reconnect option is not all that difficult. While it's certainly nice to do push, the limitation is certainly understandable from a billed-resources perspective. Basically, to do it, you build into your AJAX request handlers a setTimeout command which queues up a request for a new connection in X milliseconds. To make it easier, I even recommend pushing request parameters onto a stack, and then having a run queue function that's executed periodically. That 'rq' function pops out whatever's on the stack and uses it to determine what sort of job needs to be done. That might be updating a display, doing an AJAX request, saving work in progress, issuing an alert to the user. It's a nice way to manage tasks.

So if you want use server push, you have to let clients disconnect every 30 seconds, then build new connections( maybe use AJAX ). Gmail is doing this way, but I think it's very difficult to do it. 2009/4/20 q2 tauru...@gmail.com I am planning to create a web application that will use BlazeDS server to push data to Flash clients. Would I be able to install it in Google App Engine environment? It comes bundles with Tomcat server, so probably I would need to install Tomcat as well. Also, this sentence about Google App Engine Sandbox makes me doubt that I can use any kind of push HTTP technology in Google App Engine: Application code only runs in response to a web request or a cron job Does that mean I'm not supposed to broadcast?

[google-appengine] Re: Disappointed with free quota changes (probably not surprising)
I could make a pretty good guess as to why it happened. Google's major income is from advertising, and while they're not going broke any time soon, the amount of money coming in from their advertising has dropped significantly, and so things they could have done as loss leaders to get more advertising dollars now are weighing more on the budget, so they needed to lower the payment bar on this service. I'm sure they set the initial quotas with best intentions, but crunching some numbers, found that it was not going to be profitable. However, as with Gmail service, where the disk space available just keeps growing and growing, I'd be willing to bet that as AppEngine matures, we might see some new features and/or changes in quotas to make it even more appealing than it was in the pre-quota-change days. That having been said, there may be other reasons for the change. when they set the initial quotas, they did it based on a light- processing app getting, IIRC, 5 million hits per month. That number hasn't changed. It could very well be that when they set the quotas, they were thinking of the 5 million hits per month and it turns out that with proper accounting in place, what they were offering was enough for 50 or 500 million. I understand your frustration. I do. And they certainly could have handled this better so that it wouldn't feel like a bait-and-switch. But at the end of the day, the amount of free service they are offering is pretty substantial and for every case like yours I'd bet there are hundreds of people who are going to be able to start a business and get it profitable before they have to pay a dime. If this is for a non-profit organization, it still isn't the end of the world. I'm sure that the organization has grant writers who could get a $1,000/year grant to pay for the hosting without a problem, if it's going to help them do their good works. Good luck; I hope that the optimizations aren't too difficult, and that you can find some way to stay under those quotas. Keep the community posted!

By my calculations, it could cost me $1000 over the next year to host my app that I had anticipated being hosted under the quotas. It may cost me nothing right now our usage is just under the daily CPU limits. If the traffic doesn't grow, no problem But whose goal is it for an app not to get more usage? My only real gripe is that App Engine caused me to invest a lot of effort in shoe-horning my app into the Google Way. I did that with the understanding that the trade-off was a certain amount of free hosting. Was that a promise? Of course not. Is Google under any obligation to meet my expectation? No. However, as I attempt to further optimize the application in an effort to not exceed limits, the future of the application is now in question. This is not a profit deal. I gave away my time in an effort to help an organization. Had I known this change was coming, I probably would have chosen a different solution. Because of the vendor lock-in of App Engine, the end result of all this may be simply turning the app off and letting the organization do without. (or find someone else to help them out.) Better that than hit daily free limits or find money out of someone's pocket. Look $1000/year is not a big deal for world-class hosting. I get it. I also understand that the free quotas are only there to get people hooked such as it were. I guess I wish had listened to those who said, Don't do App Engine. They'll lock you in and change the deal. It's not portable enough. Shame on me, I guess. And before people chime in with all the, You could always move it to..., or If you had just written it this way... or It's a business, of course they're trying to get you to go over the limits.. please don't. This is just a note to let the people at Google know there is a very real cost to changing the deal on people. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Cloud Computing
The greatest advantages of AppEngine are the ease of set-up, the scalability, and the fact that your application is available throughout the infrastructure that Google has built worldwide the moment you publish. If you need a python-based environment and are OK with the limitations of AE--proprietary non-relational datastore, some python libraries not available--it's a great way to get started. There's no cost while you're building your app, and if it's not a resource hog, you might even get to run it in production mode for free for some time. But if you need finer-grain control over your environment, and you'd prefer the type of cloud system that allows you to spawn virtualized servers, then you may want to look into one of the other services. Amazon EC2 is a good one, and I've heard good things about SliceHost. Instead of a limited application environment, those services allow you to configure a virtual server which functionally is the same as a physical server, but which is running on a cloud layer in those companies' infrastructure. Personally, after years of administrating linux boxes, I'm thrilled to move what I can to systems like AppEngine. It's not the right solution for everything, though; neither are any of them. Your question about which is the best one is kind of like if you were going to build something and you asked, What's the best tool? A hammer or a saw? Depending on the job, you might need just one, just the other, or both. --BIC On Feb 24, 1:07 am, SANMI ssa...@gmail.com wrote: We have an application and I would want to introduce it in Cloud Computing.
