Hi Guys,
My app is Twitterautofollow. I have a question about the quota, basically
my app was serving between 6-13 requests a second and jumped up to 32
requests per-second and subsequently went over the quota. I am not sure
where the 32 requests a second are comming from although some of them might
come from my ping service that I am running to regularly perform some tasks
- I wouldn't be suprised if it was a bug I created
Additionally the DataStore CPU Time is Limited even though it is only at 3%
of quota.
Its starting to get a bit frustrating at the moment because I am having Data
Store Timeouts very often on reads and puts. Nothing in my model is in an
EntityGroup, that is, there is no use of parent, however there are many
RefernceProperties.
The general process I have that is causing the process goes as follows
1. Get the user (User Entity) from the datastore
2. Get the current search term (Search Entity) for the user - I don't use
the refernce propery set from the user because I need to filter it
1. Query Twitter
2. For up to 3 search results add a new entity of type "Follow" and
reference the search and user
1. For each result check to see if the "Follow" entity already
exists for the user - if it does we ignore the result
3. update the search entity with some basic stats
Overall there are, with 5 (1 user, 1 search and 3 reads of Follow) reads and
up to 4 puts (3 for new entities 1 for the "Search" entity). I don't think
this is too heavy, but it might be.
So my question is, am I being too excessive, why would this cause a lot of
datastore timeouts in both the reads and puts? What tips do people have for
DataStore performance?
Thanks,
Paul
