=== client.cluster.putComponentTemplate

Create or update a component template. Creates or updates a component template. Component templates are building blocks for constructing index templates that specify index mappings, settings, and aliases. An index template can be composed of multiple component templates. To use a component template, specify it in an index template’s `composed_of` list. Component templates are only applied to new data streams and indices as part of a matching index template. Settings and mappings specified directly in the index template or the create index request override any settings or mappings specified in a component template. Component templates are only used during index creation. For data streams, this includes data stream creation and the creation of a stream’s backing indices. Changes to component templates do not affect existing indices, including a stream’s backing indices. You can use C-style `/* *\/` block comments in component templates. You can include comments anywhere in the request body except before the opening curly bracket.
