Ancestor relation in datastore

Question

I have three entities: user, post and comment. A user may have multiple posts and a post may ha

Answer 1

I think the question to ask is: Are you expecting:

• User to create Posts more than once per seconds (I doubt :)
• People to comment on a Post more than once per second (could happen)

It not, then having ancestors queries will be faster than normal queries. So it depends of your usecase. I'd go for query speed unless you know you will have thousands of comments on posts.
