By given an entity ID , I will query by models = Model.get_by_id(id). However, I find out that some time it will not return result collectly.
Is there any alternative or recommended method to query by entity ID in Google App Engine, python?
The problem disappear by itself after the 2011-05-10, which is the v1.5 launch date. Not sure this problem is related.
I didn’t change any code, as the get_by_id() was fine all the while and on this few days. Beside, I added a cron job to run the get_by_id() every minutes and try to get the instance alive.
From my observation, the get_by_id() failed because it couldn’t query the datastore.
Btw, the setting of datastore is Master/Slave Replication.
