Index Settings

action: index_settings
description: "Change settings for selected indices"
options:
  index_settings:
    index:
      refresh_interval: 5s
  ignore_unavailable: False
  preserve_existing: False
filters:
- filtertype: ...

Empty values and commented lines will result in the default value, if any, being selected. If a setting is set, but not used by a given action, it will be ignored.

This action updates the specified index settings for the selected indices.

While Elasticsearch allows for either dotted notation of index settings, such as

PUT /indexname/_settings
{
  "index.blocks.read_only": true
}

or in nested structure, like this:

PUT /indexname/_settings
{
  "index": {
    "blocks": {
      "read_only": true
    }
  }
}

In order to appropriately detect static vs. dynamic settings, and to be able to verify configurational integrity in the YAML file, Curator does not support using dotted notation.
