Get mapping API

edit

Get mapping API

edit

Retrieves mapping definitions for one or more indices. For data streams, the API retrieves mappings for the stream’s backing indices.

response = client.indices.get_mapping(
  index: 'my-index-000001'
)
puts response

res, err := es.Indices.GetMapping(es.Indices.GetMapping.WithIndex("my-index-000001"))
fmt.Println(res, err)

GET /my-index-000001/_mapping

Request

edit

GET /_mapping

GET /<target>/_mapping

Prerequisites

edit

If the Elasticsearch security features are enabled, you must have the view_index_metadata or manage index privilege for the target data stream, index, or alias.

Path parameters

edit

<target>: (Optional, string) 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.

Query parameters

edit

allow_no_indices

(Optional, 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. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

Defaults to true.

expand_wildcards

(Optional, 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. Valid values are:

all: Match any data stream or index, including hidden ones.
open: Match open, non-hidden indices. Also matches any non-hidden data stream.
closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
none: Wildcard patterns are not accepted.

Defaults to open.

ignore_unavailable

(Optional, Boolean) If false, the request returns an error if it targets a missing or closed index. Defaults to false.

local

(Optional, Boolean) If true, the request retrieves information from the local node only. Defaults to false, which means information is retrieved from the master node.

master_timeout

(Optional, time units) 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. Defaults to 30s.

Examples

edit

Multiple data streams and indices

edit

The get mapping API can be used to get more than one data stream or index with a single call. General usage of the API follows the following syntax: host:port/<target>/_mapping where <target> can accept a comma-separated list of names. To get mappings for all data streams and indices in a cluster, use _all or * for <target> or omit the <target> parameter. The following are some examples:

response = client.indices.get_mapping(
  index: 'my-index-000001,my-index-000002'
)
puts response

GET /my-index-000001,my-index-000002/_mapping

If you want to get mappings of all indices in a cluster, the following examples are equivalent:

$params = [
    'index' => '*',
];
$response = $client->indices()->getMapping($params);
$params = [
    'index' => '_all',
];
$response = $client->indices()->getMapping($params);
$response = $client->indices()->getMapping();

response = client.indices.get_mapping(
  index: '*'
)
puts response

response = client.indices.get_mapping(
  index: '_all'
)
puts response

response = client.indices.get_mapping
puts response

{
	res, err := es.Indices.GetMapping(es.Indices.GetMapping.WithIndex("*"))
	fmt.Println(res, err)
}

{
	res, err := es.Indices.GetMapping(es.Indices.GetMapping.WithIndex("_all"))
	fmt.Println(res, err)
}

{
	res, err := es.Indices.GetMapping()
	fmt.Println(res, err)
}

GET /*/_mapping

GET /_all/_mapping

GET /_mapping
