ISM Settings

We don’t recommend changing these settings; the defaults should work well for most use cases.

Index State Management (ISM) stores its configuration in the .opendistro-ism-config index. Don’t modify this index without using the ISM API operations.

All settings are available using the Elasticsearch _cluster/settings operation. None require a restart, and all can be marked persistent or transient.
