Analyze the index disk usage Technical preview
Analyze the disk usage of each field of an index or data stream. This API might not support indices created in previous Elasticsearch versions. The result of a small index can be inaccurate as some parts of an index might not be analyzed by the API.
Path parameters
-
Comma-separated list of data streams, indices, and aliases used to limit the request. It’s recommended to execute this API with a single index (or the latest backing index of a data stream) as the API consumes resources significantly.
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 withfoo
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
. -
flush boolean
If
true
, the API performs a flush before analysis. Iffalse
, the response may not include uncommitted data. -
run_expensive_tasks boolean
Analyzing field disk usage is resource-intensive. To use the API, this parameter must be set to
true
.
