Get mapping API
editGet mapping API
editRetrieves mapping definitions for one or more indices. For data streams, the API retrieves mappings for the stream’s backing indices.
GET /my-index-000001/_mapping
Before 7.0.0, the mappings definition used to include a type name. Although mappings
in responses no longer contain a type name by default, you can still request the old format
through the parameter include_type_name
. For more details, please see Removal of mapping types.
Path parameters
edit-
<target>
-
(Optional, string) Comma-separated list of data streams, indices, and index aliases used to limit the request. Wildcard expressions (
*
) are supported.To target all data streams and indices in a cluster, omit this parameter or use
_all
or*
.
Query parameters
edit-
allow_no_indices
-
(Optional, Boolean) If
false
, the request returns an error when a wildcard expression, index alias, or_all
value targets only missing or closed indices.Defaults to
true
. -
expand_wildcards
-
(Optional, string) Controls what kind of indices that wildcard expressions can expand to. Multiple values are accepted when separated by a comma, as in
open,hidden
. Valid values are:-
all
- Expand to open and closed indices, including hidden indices.
-
open
- Expand only to open indices.
-
closed
- Expand only to closed indices.
-
hidden
-
Expansion of wildcards will include hidden indices.
Must be combined with
open
,closed
, or both. -
none
- Wildcard expressions are not accepted.
Defaults to
open
. -
-
include_type_name
-
[7.0.0]
Deprecated in 7.0.0. Mapping types have been deprecated. See Removal of mapping types.
(Optional, Boolean) If
true
, a mapping type is expected in the body of mappings. Defaults tofalse
. -
ignore_unavailable
-
(Optional, Boolean) If
false
, the request returns an error if it targets a missing or closed index. Defaults tofalse
. -
local
-
(Optional, Boolean) If
true
, the request retrieves information from the local node only. Defaults tofalse
, which means information is retrieved from the master node. -
master_timeout
-
(Optional, time units) Specifies the period of time 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
editMultiple data streams and indices
editThe 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:
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:
GET /*/_mapping GET /_all/_mapping GET /_mapping
