> Implement dynamic compression type selection and fallback for client telemetry

>
> Key: KAFKA-19506
> URL: https://issues.apache.org/jira/browse/KAFKA-19506
> Project: Kafka
> Issue Type: Bug
> Reporter: Kaushik Raina
> Assignee: Kaushik Raina
> Priority: Major
> Fix For: 4.2.0
>
>
> Kafka clients currently select the first compression type offered by the
> broker for telemetry push, often leading to errors if the required
> compression library (e.g., zstd, lz4, snappy) is not present in the client
> runtime. This causes telemetry push failures, while produce requests continue
> to work normally. Gzip is generally reliable as it is always present in the
> JDK, but other algorithms can trigger fatal exceptions, stopping further
> telemetry pushes.
> This ticket proposes enhancing the Kafka client to dynamically select the
> best available compression type at runtime. If the initial compression
> attempt fails (e.g., due to a missing dependency), the client should
> automatically retry using the next broker-supported compression type. If none
> are available, it must gracefully fall back to sending uncompressed telemetry
> data, ensuring telemetry push always succeeds regardless of deployment
> environment or available libraries.
