My hope was to the see existing segments being repartitioned via accountId on different instances and the number or replicasPerPartition to increase to 3 from 1.However I did not seem any changes in the existing segments not did I see change in replicas not did I see any new props added to the segments https://docs.pinot.apache.org/operators/operating-pinot/tuning/routing

column.accountId.partitionFunction = Module
column.accountId.numPartitions = 4
column.accountId.partitionValues = 1
