Description Kyle M Hall 2020-03-02 17:46:54 UTC
Would it be worthwhile to switch from Memcache to Redis? Redis has pub/sub which in theory would allow all processes to listen for syspref changes and update their L1 caches if necessary.

What made me think of this is bug 23640

I have no idea if this is worth the time and effort, but it seems like it would solve the major issue we have with memcached.

This was filed almost 4 years ago - have we come to a decision about this?

I don't think it's ever been discussed anywhere other than me filing this bug.

I don't think it would really work anyway. We need to flush the L1 caches after each request for more reasons than just sysprefs as well I believe.
