Can't use Redis as cache server #2133
Description
HI, I am new to Cortex and working on a POC see how it work and suitable for my infrastructure,
while I am testing to config with Redis cache server I got the following errors when I do query.
level=error ts=2020-02-14T04:58:54.186907969Z caller=redis_cache.go:87 msg="failed to get from redis" name=store.index-cache-read.redis err="ERR wrong number of arguments for 'mget' command"
