Set up a Multiple Master Master Redis DB cluster

[kaushal...@gmail.com]

Hi,

I am running Redis 6.2.4 version on CentOS Linux release 7.9.2009 (Core). I am using Redis In-Memory cache for Drupal CMS Application 8.9.16 deployed on multiple nodes Virtual Machine Node1 and Virtual Machine Node2 setup behind Load Balancer. 

Is there a way to set up a Multiple Master Master Redis DB cluster wherein Node1 VM will talk to Node2 and vice versa to set up HA and Fault-tolerant resilient infrastructure? Thanks in Advance.

Best Regards,

Kaushal

The free open source Redis server does not support multiple masters.  There is a sharded version of the free open source Redis (titled Redis Cluster) which divides the data into 3 or more shards (parts), and each shard has one master and one (or more) slaves.  This sounds like it's not really what you're asking for, but I thought I'd mention it.
