I have a popular app making around 15 to 30 calls per minute. CPU
usage is high but within limits.
Sample usage: 500 4027ms 35cpu_ms 16api_cpu_ms 0kb
High: 500 4291ms 820cpu_ms 645api_cpu_ms
I get these errors a few times every hour. Please note that it is a
GET call.
q = Question.get_by_id(int(qid))
File "/base/python_lib/versions/1/google/appengine/ext/db/
__init__.py", line 1001, in get_by_id
return get(*keys)
File "/base/python_lib/versions/1/google/appengine/ext/db/
__init__.py", line 1182, in get
entities = datastore.Get(keys)
File "/base/python_lib/versions/1/google/appengine/api/
datastore.py", line 257, in Get
raise _ToDatastoreError(err)
Timeout
Is this an app engine problem ? Or it is because the other calls are
trying to write into this entry but this call is trying to read. I see
a lot of wait time (in the profiling data).
Based on your response, I will go ahead and try to change my db and
the code.
Pls note that I have a user db and question db. When A answers
question Q posted by user B, I update A, B and Q. Will really
appreciate your response. I am a big fan of app engine and using app
engine a lot !
