描述

I think it was decided at some point to deprecate replicaGroupStrategyConfig.

However, right now there's no way to ensure that two tables are partitioned on a given column across the same set of instances, except using a combination of instancePartitionsMap and replicaGroupStrategyConfig.

Given this, let's make sure this is addressed before the config is removed from OSS.

研究方向
Investigate the current usage of replicaGroupStrategyConfig in Pinot's source code, particularly in configuration classes and partitioning logic. Review the discussion in comments for proposed alternatives. Identify how instancePartitionsMap and replicaGroupStrategyConfig are jointly used to ensure co partitioning. Propose a solution to maintain that functionality after deprecation, possibly by extending instancePartitionsMap or introducing a new configuration field. Document the findings and initiate a discussion on the best path forward.
