=== Get Data Frame Transform Stats API

The Get Data Frame Transform Stats API is used read the operational statistics
of one or more {dataframe-transform}s.
The API accepts a +{request}+ object and returns a +{response}+.

==== Get Data Frame Transform Stats Request

A +{request}+ requires a data frame transform id or the special wildcard `_all`
to get the statistics for all {dataframe-transform}s

[id="{upid}-{api}-response"]
==== Response

The returned +{response}+ contains the requested {dataframe-transform} statistics.

include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> The response contains a list of `DataFrameTransformStateAndStats` objects
<2> The running state of the transform task e.g `started`
<3> The running state of the transform indexer e.g `started`, `indexing`, etc.
<4> The overall transform statistics recording the number of documents indexed etc.
<5> The progress of the current run in the transform. Supplies the number of docs left until the next checkpoint
and the total number of docs expected.
