When the `_reindex` API is used with a remote source (`source.remote` is set in the request body), neither manual slicing (via `source.slice` in the request body) nor automatic slicing (via the `slices` URL parameter) are supported. Prior to this change, on sending a request with a remote source and manual slicing enabled, the manual slicing specification would be ignored, and the complete source would be reindexed without slicing. After this change, the API will return a response with an HTTP code 400 (Bad Request) instead. The new behaviour more correctly indicates to the user that the requested functionality is not available, rather than silently ignoring part of their request. Note that: - Prior to this change, sending a request with a remote source and *automatic* slicing enabled already resulted in the correct 400 response. - The [docs](https://www.elastic.co/docs/reference/elasticsearch/rest-apis/reindex-indices#docs-reindex-slice) already correctly stated "Reindexing from remote clusters does not support manual or automatic slicing." - As a drive-by, this change also adds a unit test for the validation with the `slices` parameter set to `auto`. (Previously, only the case where it was set to a number greater than 1 was tested.) Closes elastic#136269

When the
_reindexAPI is used with a remote source (source.remoteis set in the request body), neither manual slicing (viasource.slicein the request body) nor automatic slicing (via theslicesURL parameter) are supported.Prior to this change, on sending a request with a remote source and manual slicing enabled, the manual slicing specification would be ignored, and the complete source would be reindexed without slicing. After this change, the API will return a response with an HTTP code 400 (Bad Request) instead.
The new behaviour more correctly indicates to the user that the requested functionality is not available, rather than silently ignoring part of their request.
Note that:
Prior to this change, sending a request with a remote source and automatic slicing enabled already resulted in the correct 400 response.
The docs already correctly stated "Reindexing from remote clusters does not support manual or automatic slicing."
As a drive-by, this change also adds a unit test for the validation with the
slicesparameter set toauto. (Previously, only the case where it was set to a number greater than 1 was tested.)Closes #136269
