No TTL set on entity keys

[bencrouse]

Our Redis instance filled up with keys because there's no TTL set on the entity keys. I see that Rack::Cache doesn't provide TTL to the MetaStore#write method, but I'm wondering if there's a suggested workaround or fix that could be done to prevent an unbounded number of keys. I'd be willing to do the work if there's an acceptable solution.

Seeing this as an issue as well.

@mezis Has this now been fixed by redis-store/redis-store#209?

[mezis]

@radar it has indeed. Sorry I didn't ping back to this issue!

[mezis]

Well, to be specific, when use_native_ttl is set and using redis-store >= 1.1.5, the entity store no longer eventually overflows.

The metastore still doesn't support native TTLs.

[bencrouse]

we were experiencing the problem with the metastore keys.

[radar]

Ok. Is another patch needed here?

[mezis]

@radar there would, but the issue has to be solved in Rack::Cache itself first. At the moment use_native_ttl isn't honoured by the metastore.

rtomayko/rack-cache#92 has a proposed fix but it's been open for a long while.

Fixed by #4 and #5.
