Method Details
-
fromIndexMetadata
Build the routing fromIndexMetadata
. -
indexShard
public abstract int indexShard(String id, @Nullable String routing, org.elasticsearch.xcontent.XContentType sourceType, BytesReference source) Called when indexing a document to generate the shard id that should contain a document with the provided parameters. -
updateShard
Called when updating a document to generate the shard id that should contain a document with the provided_id
and (optional)_routing
. -
deleteShard
Called when deleting a document to generate the shard id that should contain a document with the provided_id
and (optional)_routing
. -
getShard
Called when getting a document to generate the shard id that should contain a document with the provided_id
and (optional)_routing
. -
collectSearchShards
Collect all of the shard ids that *may* contain documents with the providedrouting
. Indices with arouting_partition
will collect more than one shard. Indices without a partition will collect the same shard id as would be returned bygetShard(java.lang.String, java.lang.String)
.Note: This is called for any search-like requests that have a routing specified but only if they have a routing specified. If they do not have a routing they just use all shards in the index.
-
hashToShardId
protected final int hashToShardId(int hash) Convert a hash generated from an(id, routing
) pair into a shard id.
