Our application was running with 1 user this morning and received a
datastore timeout.
The code has no loops in it, it gets 1 row each from 4 entities, 2 of
them by key using get_or_insert and 2 of them using a reference
property. They are all root entities and there is no contention as
you can see from the log below. The tables all have <1000 rows in
them. The timeout happened on the first datastore call using
get_or_insert. Even if I retried this call it is bananas waiting 3
seconds for a single row to come back.
Am I better off doing a get and if that fails then trying the
get_or_insert?
It looks like other applications running on the server are affecting
my application. If I was being billed I believe this would cost me
money.
Here's the log, no transactions have been removed, the two
transactions at 2:11AM failed with a huge cpu spike.
