.Reindex from remote now re-encodes URL-encoded index names.
|
|
[%collapsible]
|
|
====
|
|
*Details* +
|
|
Reindex from remote would previously allow URL-encoded index names and not
|
|
re-encode them when generating the search request for the remote host. This
|
|
leniency has been removed such that all index names are correctly encoded when
|
|
reindex generates remote search requests.
|
|
|
|
*Impact* +
|
|
Specify unencoded index names for reindex from remote requests.
|
|
====
|
|
|
|
.Reindex-related REST API endpoints containing mapping types have been removed.
|
|
[%collapsible]
|
|
====
|
|
*Details* +
|
|
The `/{index}/{type}/_delete_by_query` and `/{index}/{type}/_update_by_query` REST endpoints have been removed in favour of `/{index}/_delete_by_query` and `/{index}/_update_by_query`, since indexes no longer contain types, these typed endpoints are obsolete.
|
|
|
|
*Impact* +
|
|
Use the replacement REST API endpoints. Requests submitted to API endpoints
|
|
that contain a mapping type will return an error.
|
|
====
|
|
|
|
|
|
.In the reindex, delete by query, and update by query APIs, the `size` parameter has been renamed.
|
|
[%collapsible]
|
|
====
|
|
*Details* +
|
|
Previously, a `_reindex` request had two different size specifications in the body:
|
|
|
|
- Outer level, determining the maximum number of documents to process
|
|
- Inside the `source` element, determining the scroll/batch size.
|
|
|
|
The outer level `size` parameter has now been renamed to `max_docs` to
|
|
avoid confusion and clarify its semantics.
|
|
|
|
Similarly, the `size` parameter has been renamed to `max_docs` for
|
|
`_delete_by_query` and `_update_by_query` to keep the 3 interfaces consistent.
|
|
|
|
*Impact* +
|
|
Use the replacement parameters. Requests containing the `size` parameter will
|
|
return an error.
