Hi,
I'm interested in knowing how well multiple OR (||) statements would
operate in a single query. For example, I want to find all friends
that have recommended a particular product:
Query query = pm.newQuery(Recommendation.class,
"(username == 'turtle' ||
username == 'frog' ||
username == 'rock') &&
productid == '123'");
if a user has 200 friends, and I created a huge string as above, what
can I expect to happen? Should the query take a very long time to run?
Can app engine break the query apart and run each part in parallel?
Even if performance is ok, will I be using a lot of my CPU quota every
time this is called?
Thanks
