Update settings
Introduced 0.1.0
You can use the update settings API operation to update index-level settings. You can change dynamic index settings at any time, but static settings cannot be changed after index creation. For more information about static and dynamic index settings, see Create index.
Aside from the static and dynamic index settings, you can also update individual plugins’ settings. To get the full list of updatable settings, run GET <target-index>/_settings?include_defaults=true.
Example
PUT /sample-index1/_settings
{
"index.plugins.index_state_management.rollover_skip": true,
"index": {
"number_of_replicas": 4
}
}
Path and HTTP methods
