Using Redis then dump data is just great

Hello,
Discourse is using Redis to store live data, and dumps this data periodically to the database.
This is such a great idea, It makes scalability very easy and cheap.
I want to learn more about this architecture, does it have a special name ? So I can go with my searching forward.

Thank you.

No, that is not what we do, Postgres is used for the DB and Redis is used as an in memory and cross server cache.

So, for example, when I like your comment, do I hit the database directly ? Jeff ? @codinghorror

Yes it does.

You should read the source code to learn more about how Discourse works :wink:

Hey,
Sorry I’m not very good with Ruby, can you point the class or the method that does this ?
Thank you.
