[appengine-java] Re: Java low level API type conversions
For numbers you can use the java.lang.Number its the parent class of all numbers. It has methods like shortValue(), longValue() ... that you can use to extract values. For Lists just extract a Collection and convert the collection to a list. Strings are the most complicated, because a you need a Text value to store greater than 500 chars, so just do a simple instanceof to test if type Text or String. When going into the datastore you should generally store as Text except where you need the value to be indexed, in which case you have to use string.

Everything in the /apparent/ design of Appengine happens in the context of a user request - logging, billing, quotas - everything. While I'd love to see a really smart version of appengine spin up new instances while the old ones continue to serve, I wouldn't hold my breath.

[appengine-java] Re: Performance Issues
Join the google dosent care about app engine performance club. To see how much google dosent care just check out their own app engine status page. http://code.google.com/status/appengine Isnt it funny how google lectures the whole world about how the web should be faster? Also some things you can do do fix performance to make it as slow(fast) as google app engine will allow. Override the DataStoreService interface making your own version that logs each round trip to a console output. This will help you learn how many round trips your making to datastore. Also google discourages cron pinggers but with them not providing a decent solution who can blame you.

The application that was not created under my account (but for which I'm an administrator) doesn't have much traffic yet, but when it goes live will probably have a few thousand requests per day. For now we are having a cron job running every minute to keep the application alive. But most of the time the cron job is not running on time. There is a red message that displays that the job was run 5 seconds or more too late. Even some cron jobs fail. With no traffic to my application (only the cron job running) the graph on my dashboard isn't a nice flat line with an average of 1 request per minute (0,0167 requests per second). We see a lot of peeks going from 0,005 to 0,02 requests per minute. When I deploy the same application on my own account (greated a new application in my account but deployed the same webapp), the performance is like I would expect. With no traffic and only the cron job running we get a nice graph with 0,0167 requests per second. The line is almost flat and no cron jobs are running late. Even no cron jobs fail. Also for simple request I see a performance difference between the two applications. I'm having a also a high CPU job that I need to run. This work am I doing with queues. When I execute the work in both applications, the slow application can only execute 3 to 4 tasks per minute, with the other one can run the same task with the same data 5 to 6 times a minute. I would expect that both apps would behave in the same way and almost no notable performance difference, but this is clearly not the case. Is anyone having the same issue? What can be done about this?

[google-appengine] Re: App Engine Status Page Almost as Slow as my app
Hi Wesly thank you for your reply! Overall its not just about the status page showing up or not, I am very upset with the overall performance of app engine. Just this past night query latency spiked to over 1200ms. Google seems to not be properly addressing these issues and or treating them with the amount of severity they deserves. I have spend the past 5 months developing my application and have been recently doing everything possible to optimize my code but when a single query takes over a second to run this becomes impossible. When the Feb 24th outage accord Google replied swiftly and treated the problem with a war room like mentality, I would like the same treatment for these performance issues.
