.The `listener` thread pool has been removed.

[%collapsible]
|
|
====
|
|
*Details* +
|
|
Previously, the transport client used the thread pool to ensure listeners aren't
|
|
called back on network threads. The transport client has been removed
|
|
in 8.0, and the thread pool is no longer needed.
|
|
|
|
*Impact* +
|
|
Remove `listener` thread pool settings from `elasticsearch.yml` for any nodes.
|
|
Specifying `listener` thread pool settings in `elasticsearch.yml` will result in
|
|
an error on startup.
|

|
|
.The `fixed_auto_queue_size` thread pool type has been removed.
|
|
[%collapsible]
|
|
====
|
|
*Details* +
|
|
The `fixed_auto_queue_size` thread pool type, previously marked as an
|
|
experimental feature, was deprecated in 7.x and has been removed in 8.0.
|
|
The `search` and `search_throttled` thread pools have the `fixed` type now.
|
|
|
|
*Impact* +
|
|
No action needed.
