Re: [appengine-java] Appstats make request to API call memcache.Set() was too large
I see same problem. I cant use appstats with my app. Can I configure to reduce appstats-data of each RPC call? Uncaught exception from servlet com/google/net/rpc/RpcStub.java:1025:in `runInContext': com.google.apphosting.api.ApiProxy$RequestTooLargeException: The request to API call memcache.Set() was too large.

[appengine-java] Query returns more than limit
Hello, I have seen problem with Java, like this: > - Fixed a datastore issue where an error was thrown when setting a query > offset > to more than the number of results throws an error. > http://code.google.com/p/googleappengine/issues/detail?id=2875 I send this query: query.filter(:user_id=>user.id).sort(:created_at, :desc).each(:limit=>3) This query uses composite-index. UserNews user_id ▲ , created_at ▼ I set limit=3, but many (all?) entities are return. It is not always. very very rare case. This code is ruby, but I trace code, I found JavaAPI's PreparedQuery#asIterator(FetchOptions fetchOptions) is used. >From application log. Maybe query is retried, by application code. I am using deadline=3.0sec. First query is deadlined, and retryed.

[appengine-java] ApiProxy$ApplicationException
Hello, I see many strange errors. (1) ApiProxy$ApplicationException: ApplicationError: 2: too much contention on these datastore entities. please try again. It should be converted to ConcurrentModificationException. (2) ApiProxy$ApplicationException: ApplicationError: 5: Unknown I set deadline( http://code.google.com/intl/en/appengine/docs/java/javadoc/com/google/appengine/api/datastore/DatastoreServiceConfig.html#deadline%28double%29 ).

[appengine-java] HardDeadlineExceededError with JRuby. Runtime changed??

[appengine-java] CPU Quota Service is working?
Hi,
I tried quota service.
http://code.google.com/intl/ja/appengine/docs/java/javadoc/com/google/appengine/api/quota/QuotaService.html
CODE(jruby):
def current_quotas
qs = com.google.appengine.api.quota.QuotaServiceFactory.getQuotaService
cpu_cycles = qs.getCpuTimeInMegaCycles
cpu_sec = qs.convertMegacyclesToCpuSeconds(cpu_cycles)
cpu_supports =
qs.supports(com.google.appengine.api.quota.QuotaService::DataType::CPU_TIME_IN_MEGACYCLES)
api_cycles = qs.getApiTimeInMegaCycles
api_sec = qs.convertMegacyclesToCpuSeconds(api_cycles)
api_supports =
qs.supports(com.google.appengine.api.quota.QuotaService::DataType::API_TIME_IN_MEGACYCLES)
return {:cpu=>{:cycles=>cpu_cycles, :sec=>cpu_sec, :supports=>cpu_supports},
:api=>{:cycles=>api_cycles, :sec=>api_sec, :supports=>api_supports}}
end
RESULT:
{:cpu=>{:cycles=>0, :sec=>0.0, :supports=>true}, :api=>{:cycles=>930,
:sec=>0.775, :supports=>true}}
I got API quota values, but CPU is always 0.
Anyone know CPU-quota service is working?
