Method: Elasticsearch::API::Indices::Actions#get_mapping

Defined in:
lib/elasticsearch/api/actions/indices/get_mapping.rb

#get_mapping(arguments = {}) ⇒ Object

Get mapping definitions. For data streams, the API retrieves mappings for the stream’s backing indices.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :index (String, Array) —

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (‘*`). To target all data streams and indices, omit this parameter or use `*` or _all.

  • :allow_no_indices (Boolean) —

    If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. Server default: true.

  • :expand_wildcards (String, Array<String>) —

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as ‘open,hidden`. Server default: open.

  • :ignore_unavailable (Boolean) —

    If false, the request returns an error if it targets a missing or closed index.

  • :local (Boolean) —

    If true, the request retrieves information from the local node only.

  • :master_timeout (Time) —

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.

  • :error_trace (Boolean) —

    When set to true Elasticsearch will include the full stack trace of errors when they occur.

  • :filter_path (String, Array<String>) —

    Comma-separated list of filters in dot notation which reduce the response returned by Elasticsearch.

  • :human (Boolean) —

    When set to true will return statistics in a format suitable for humans. For example ‘“exists_time”: “1h”` for humans and `“exists_time_in_millis”: 3600000` for computers. When disabled the human readable values will be omitted. This makes sense for responses being consumed only by machines.

  • :pretty (Boolean) —

    If set to true the returned JSON will be “pretty-formatted”. Only use this option for debugging only.

  • :headers (Hash) —

    Custom HTTP headers
