Usage Note 65877: Use the adaptive replica selection feature to enable better Elasticsearch performance
 |  |  |  |  |
For Elasticsearch, it is recommended that you turn on the adaptive replica selection (ARS) feature. This feature improves search throughput as well as latency.
As stated by Elastic, ARS is available in Elasticsearch 6.1 and later, but it is turned off by default in all 6.x releases. You can turn on this feature by using the cluster.routing.use_adaptive_replica_selection setting in this way:
PUT /_cluster/settings { "transient": { "cluster.routing.use_adaptive_replica_selection": true } }
In Elasticsearch 7.0 and later, the ARS feature is turned on by default.
