Question

Does SQLAlchemy support some kind of caching so if I repeatedly run the same query it returns the response from cache instead of querying the database? Is this cache automatically cleared when the DB is updated?

Or what’s the best way to implement this on a CherryPy + SQLAlchemy setup?

Answer 1

We have a pretty comprehensive caching solution, as an example in conjunction with embedded hooks, in 0.6. It’s a recipe to subclass Query, make it aware of Beaker, and allow control of query caching for explicit queries as well as lazy loaders via query options.

I’m running it in production now. The example itself is in the dist and the intro documentation is at http://www.sqlalchemy.org/docs/orm/examples.html#beaker-caching .

UPDATE: Beaker has now been replaced with dogpile caching: http://docs.sqlalchemy.org/en/latest/orm/examples.html#module-examples.dogpile_caching
