Get index settings
Returns setting information for one or more indices. For data streams, returns setting information for the stream’s backing indices.
Path parameters
-
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
-
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. For example, a request targetingfoo*,bar*
returns an error if an index starts with foo but no index starts withbar
. -
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
. -
flat_settings boolean
If
true
, returns settings in flat format. -
include_defaults boolean
If
true
, return all default settings in the response. -
local boolean
If
true
, the request retrieves information from the local node only. Iffalse
, information is retrieved from the master node. -
master_timeout string
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.
