Currently I am working on project that's supposed to be used by a lot of people. I am worried that datastore read/write/small ops are using too much resources. Since I am new to appengine, are there any efficient ways to make those numbers smaller? I thought about using memcache but it's not most secure way. Also is it a good idea to search for datastore entities using the:
SELECT __key__ FROM table
then use:
....#code
table.get_by_id(entity.id())
....#code
?
Thank you very much.
