[GitHub] [druid] neerajtiwar opened a new issue #10192: Option needed to use multiple redis hosts for caching
neerajtiwar opened a new issue #10192:
URL: https://github.com/apache/druid/issues/10192
### Description
Currently Druid provides option to use Redis cache for Broker nodes under "druid.cache.host" property, however, it only accepts 1 IP which is not suitable for production and is not fault-tolerant. I tried giving multiple IPs of my Redis cluster but Druid is unable to use it if configured with comma seperated IPs. Below is config I used:
druid.cache.type=redis
druid.broker.cache.useCache=true
druid.broker.cache.populateCache=true
druid.cache.host=10.140.31.43,10.140.31.44,10.140.31.45
druid.cache.port=6379
druid.cache.maxTotalConnections=60
druid.cache.maxIdleConnections=60
Above config didn't throw any error but never used by DRUID, When I provided single IP it started working.

Besides cluster support, I think redis-cache extension needs to be updated to :
1. allow user to specify password of a redis node/cluster
2. allow user to customize database index of a redis node

redis-cache extension currently does NOT support redis cluster. I don't know if there's a plan to support redis cluster since it's a contrib extension created by @QiuMM
