=== Breaking changes
|
|
|
|
Script Cache::
|
|
* Script cache size and rate limiting are per-context {es-pull}55753[#55753] (issue: {es-issue}50152[#50152])
|
|
|
|
Field capabilities API::
|
|
* Constant_keyword fields are now described by their family type `keyword` instead of `constant_keyword` {es-pull}58483[#58483] (issue: {es-issue}53175[#53175])
|
|
|
|
Snapshot restore throttling::
|
|
* Restoring from a snapshot (which is a particular form of recovery) is now
|
|
properly taking recovery throttling into account (i.e. the
|
|
`indices.recovery.max_bytes_per_sec` setting).
|
|
The `max_restore_bytes_per_sec` setting is also now defaulting to
|
|
unlimited, whereas previously it was set to `40mb`, which is the
|
|
default that's used for `indices.recovery.max_bytes_per_sec`. This means
|
|
that no behavioral change will be observed by clusters where the recovery
|
|
and restore settings had not been adapted from the defaults. {es-pull}58658[#58658]
|
|
|
|
Thread pool write queue size::
|
|
* The WRITE thread pool default queue size (`thread_pool.write.size`) has been
|
|
increased from 200 to 10000. A small queue size (200) caused issues when users
|
|
wanted to send small indexing requests with a high client count. Additional
|
|
memory-oriented back pressure has been introduced with the
|
|
`indexing_pressure.memory.limit` setting. This setting configures a limit to
|
|
the number of bytes allowed to be consumed by outstanding indexing requests.
|
|

|
|
|
|
Dangling indices::
|
|
* Automatically importing dangling indices is now deprecated, disabled by
|
|
default, and will be removed in {es} 8.0. See the
|
|
<<deprecate_auto_import_dangling_indices,migration notes>>.
