COD now supports replication for the META regions, which means clients can read the META replicas first before connecting to the primary region server. This reduces the load on the META table because the read META load is distributed across multiple replicas. COD supports configuring three META replicas which can be deployed in different RegionServers. Client needs to use the COD provided configuration to get the META calls that are distributed across these replicas.
This would be useful in the case where the application has lots of clients like while accessing using spark, yarn, phoenix-spark etc.
This is available starting in COD v1.21 and you do not need to upgrade to a higher version of COD to benefit from this feature.
