This section contains modules responsible for various aspects of the functionality in Elasticsearch. Each module has settings which may be:
|
|
|
|
_static_::
|
|
|
|
These settings must be set at the node level, either in the
|
|
`elasticsearch.yml` file, or as an environment variable or on the command line
|
|
when starting a node. They must be set on every relevant node in the cluster.
|
|
|
|
_dynamic_::
|
|
|
|
These settings can be dynamically updated on a live cluster with the
|
|
<<cluster-update-settings,cluster-update-settings>> API.
