Phase out nutcracker for connecting to redis
Open, MediumPublic


Nutcracker is currently not maintained (has something like 6 commits over the last 4 years, all merging external pull requests) and is currently used only to proxy connections to the redises running on the memcached hosts.

I would like to simplify our stack by removing nutcracker from the path to redis. To substitute for it, we can:
1 - Use the sharding/failover functionality baked into RedisBagOfStuff, at the cost of slightly worse performance because we would do hash routing in PHP. The risk I see is that we'd have to enable persistent connections in php-redis
2 - Use envoy also to proxy to redis - the redis support in envoy is pretty advanced at this point and includes the ability to mirror writes, which is interesting to us. See The only risk here is that some quirks in envoy's proxying cause problems.
