  The term of the current selected primary. This is a non-negative number incremented when a primary shard is assigned after a full cluster restart or a replica shard is promoted to a primary. Note: since we increment the term every time a shard is assigned, the term for any operational shard (i.e., a shard that can be indexed into) is larger than 0. See IndexMetadataUpdater.applyChanges(org.elasticsearch.cluster.metadata.Metadata, org.elasticsearch.cluster.routing.RoutingTable).

  public Index getResizeSourceIndex()
- mappingOrDefault
  
  @Nullable public MappingMetadata mappingOrDefault()
  
  Sometimes, the default mapping exists and an actual mapping is not created yet (introduced), in this case, we want to return the default mapping in case it has some default mapping definitions.
  Note, once the mapping type is introduced, the default mapping is applied on the actual typed MappingMetadata, setting its routing, timestamp, and so on if needed.

- getRoutingNumShards
  
  public int getRoutingNumShards()
  
  Returns the number of shards that should be used for routing. This basically defines the hash space we use in OperationRouting.generateShardId(IndexMetadata, String, String) to route documents to shards based on their ID or their specific routing value.

- selectRecoverFromShards
  
  public static java.util.Set<ShardId> selectRecoverFromShards(int shardId, IndexMetadata sourceIndexMetadata, int numTargetShards)
