Description
When redistributeIndexes flag is set to true, the number of index movements during rebalance can be large. This can lead to long running rebalance. Few optimizations are possible to reduce the number of index movements:
1. When a new node is getting added, avoid movement between existing nodes of the cluster.
2. During swap rebalance, restrict the index movement between the nodes getting swapped. Currently for partitioned indexes, all indexes are eligible to move during swap rebalance.
