::::{dropdown} Deprecation of partitioner settings in the Kafka Integration

The `partitioner` configuration options `default` and `uniform_sticky` have been deprecated in the Kafka output. [#206](https://github.com/logstash-plugins/logstash-integration-kafka/pull/206)

These options will work correctly for the Kafka plugin version bundled with Logstash 9.2.x, but will be removed in a future release.

The deprecations in the Kafka output were made to align with changes in the Kafka Client.
At version 4.x, the Kafka Client removes the `DefaultPartitioner` and `UniformStickyPartitioner` partitioner implementations.
It adds an improved [uniform sticky partitioner](https://cwiki.apache.org/confluence/display/KAFKA/KIP-794%3A+Strictly+Uniform+Sticky+Partitioner), which is the default.

#### Persistent queue (PQ) compression [logstash-9.2.0-pq-compression]

We’ve added support for compression to the [Persistent Queue (PQ)](https://www.elastic.co/docs/reference/logstash/persistent-queues), allowing you to spend some CPU in exchange for reduced disk IO. This can help reduce cost and increase throughput in situations where your hardware is rate-limited or metered.
