Re: [appengine-java] Billed CPU time by far too high
If you are actually being billed, you'd fill out this form right here: http://code.google.com/appengine/kb/billing.html http://code.google.com/appengine/kb/billing.html1.3 CPU hours is still significantly under the free quota, so this probably wouldn't be an option for you. I'd advise running AppStats to profile where all the additional CPU usage is coming from. This information would be extremely helpful both to you as well as to other developers who may experience the same issues. Without knowing additional information, it's also possible that you were being *underbilled* previously and that we've corrected billing information.

The situation is as follows: I have a cron job that is triggered every minute. It has an average CPU usage of 56(17) according to the dash board. On the black list I cannot see any requests other than my cron job. It is nearly the only thing that needs CPU time. Normally what I got billed everyday was about 0.2 CPU hrs a day. In the meantime it is about 1.3 CPU hrs a day! That is more than 1/5 of the free quota just for this lightweight cron job!

[appengine-java] Benchmarking Loading Requests
(I originally posted this email to the Gaelyk list, but it actually makes sense to ask all GAE/Java developers) I'm wondering what others have done in measuring and optimizing GAE/Java loading request performance. 1) What measurements have people on this list done? 2) Does anyone have any good links to the work of others? 3) What would be some best practices? 4) Is using the CPU usage info from loading requests in the log the best method? 5) What are the best tools for collecting/analyzing this info? I should also mention that I like how Damon Oehlman has used average response time + 2 standard deviations to compare performance: http://distractable.net/coding/google-appengine-language-performance-comparison-followup/ Regards, Sean -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi
i have thausands of entries in my ah_SESSION data store table, it
dates several days back
it does not expire or delete, i think it is non sense to keep all the
sessions even that expired in the web container in the data store
if it expires , when it expires? and how to trigger that
if it does not expires or auto delete? is it a feature?
How can i delete them? do i have to do it myself? or appengine have a
setting for it?
i know i can do it in code .. but
What is your experience with it?

[appengine-java] Re: I'm new: how should I structure 3 linked tables?
Hello Cliff, For me, key things to think about in your persistence design are: 1. The maximum rates at which you want to write data to the datastore. 2. Transactions: are you going to use them not at all, a lot, or always? 3. The entity group structure of your persistent entity classes. The first two points will have an influence on the third. There is a maximum write rate to the data in each entity group. Transactions, where used, may encompass one entity group only. You can associate instances of different persistent entity classes in two ways: using a field holding (a pointer to = a reference to) the instance of the other class, or a field holding a key of the instance of the other class. The difference is that the first choice establishes an entity group relationship if this is done in the correct way (at creation-time for the child entity). Also, why not examine Max Ross's blog (http://gae-java- persistence.blogspot.com)? It's got working examples of persistence code, and I have found this helpful. There are persistence frameworks that act as a front-end for GAE/J persistence (search this forum for details). I am sure that they are good, but I personally do not use them because I want to reduce the number of independent software components in my code (Java, Apache Wicket, NetBeans, GAE/J and DataNucleus JDO are enough for me!) and keep it portable outside of GAE/J. Finally, really study the GAE/J Storing Data documentation. There is a lot in it, but for us used to SQL-compliant RDMS databases, this is a must. Finally, enjoy! -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Cache pages in Memcache
They behave differently: * Cache-control (or Expires): if the resource has not expired, the browser will not ask for it again (unless the user hits F5 or shift +F5) * ETag (or Last-Modified): the browser will ask for the resource every time, but the server can return a 304 (not modified). You can use both at the same time, and most people do.

I agree with you. The problem with setting a cache header is that you have very little control over expiration.

[appengine-java] serious problem Error 203
Hi, i have got the following error : A serious problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you should contact the App Engine team.

Re: [appengine-java] Would Blob properties slow down my queries?
Entities are fetched whole, so if you have a large Blob property and you are fetching it all the time, it would take longer than fetching an entity without a Blob property. Unless you're frequently (every request) retrieving a large Blob, this shouldn't be *that* expensive. Small blobs shouldn't take that much longer. Your mileage may vary, so you'll have to do some benchmarking to see. What are you thinking of doing?

Re: [appengine-java] Re: Cache pages in Memcache
In general web development, etags are discouraged because they don't work in multiserver clusters well. They work in our deployment well for static assets. We return the same etag for all assets for a given deployment. If you update your deployment, even if the file has not changed, we will update the etag. Honestly, I would probably just stick to cache-control or the expires header. Makes it easier to debug. On Mon, May 10, 2010 at 2:00 PM, Nacho Coloma icol...@gmail.com wrote: They behave differently: * Cache-control (or Expires): if the resource has not expired, the browser will not ask for it again (unless the user hits F5 or shift +F5) * ETag (or Last-Modified): the browser will ask for the resource every time, but the server can return a 304 (not modified). You can use both at the same time, and most people do.

I agree with you. The problem with setting a cache header is that you have very little control over expiration. The nice thing about a cache that you handle at the filter level and in Memcache is that if you can regenerate the keys, you can flush the thing (or you can flush everything if need be).

But maybe it's a good idea to have some kind of server cache too. Ehcache Web Module has a nice Java Filter that threats many corner cases (headers, gzip, ...). The only problem is that it's too coupled to Ehcache. I think I'll try to fork that project to use their Filter with AppEngine's memcache :) On May 4, 6:22 am, Nacho Coloma icol...@gmail.com wrote: Hi Sergio, I'm thinking in a Filter that put page results in memcache when first accessed, and then getting that result in former accesses. That should work. All page cache implementations do more or less the same. The idea is simple but the implementation is not. (how to get the first request response? how to implement proper header management in that filter? how to not disable gzip using this?) * If there is content in memcache, you can deliver it and exit. Otherwise, let the request proceed, and store in the cache. * Be sure to set the cache timeout and calculate the cache key correctly (e.g. include the user ID or the user locale if the cached contents depend on that). * For HTTP headers, this presentation may help: http://www.slideshare.net/icoloma/caching-web-contents-in-the-browser... It's more or less the same with JSP page fragments (except the headers, of course). No rocket science.
