public class TimeSeriesRoutingHashFieldMapper
extends MetadataFieldMapper

Mapper for the _ts_routing_hash field. The field contains the routing hash, as calculated in coordinating nodes for docs in time-series indexes. It's stored to be retrieved and added as a prefix when reconstructing the _id field in search queries. The prefix can then used for routing Get and Delete requests (by doc id) to the right shard.
