Overview

In Elasticsearch, persistent refers to cluster settings that persist across cluster restarts. This setting is used in Cluster Update API calls. Persistent settings can also be configured in the elasticsearch.yml file.

Examples

## enable shard routing
PUT /_cluster/settings
{
    "persistent" : {
        "cluster.routing.allocation.enable" : "all"
    }
}
## enable rebalancing of shards
PUT /_cluster/settings
{
    "persistent" : {
        "cluster.routing.rebalance.enable" : "all"
    }
}
## limit the heap size for fielddata
PUT /_cluster/settings
{
    "persistent" : {
                 “indices.breaker.fielddata.limit”: "30%"
    }
}
