Cluster changes
The changes related to cluster are as follows:
- The colon (:) is not a valid character for the cluster name anymore due to cross-cluster search support.
- The number of allocated shards (wait_for_active_shards) that must be ready before the open index API can be proceeded has been incremented from 0 to 1.
- The shard preferences in the search APIs, including _primary, _primary_first, _replica, and _replica_first, are eliminated.
- The cluster-wide shard limit used to prevent user error now depends on the value of max_shards_per_node * number_of_nodes.
