 $$$routing-partition-size$$$ `index.routing_partition_size`
 :   The number of shards a custom routing value can go to. Defaults to 1 and can only be set at index creation time. This value must be less than the `index.number_of_routing_shards` unless the `index.number_of_routing_shards` value is also 1. for more details about how this setting is used, refer to [](/reference/elasticsearch/mapping-reference/mapping-routing-field.md#routing-index-partition).
