Sven Ludwig commented on KAFKA-5686:
------------------------------------
I just tried to set LZ4 in the configuration of Kafka Broker which leads to a
fatal that says it should be lower case lz4.
{{[2017-12-29 13:55:15,393] FATAL [KafkaServer id=1] Fatal error during
KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

Please consider this difference between API and Broker-Configuration.

> Documentation inconsistency on the "Compression"
> ------------------------------------------------
>
> Key: KAFKA-5686
> URL: https://issues.apache.org/jira/browse/KAFKA-5686
> Project: Kafka
> Issue Type: Bug
> Components: documentation
> Affects Versions: 0.11.0.0
> Reporter: Seweryn Habdank-Wojewodzki
> Assignee: Manikumar
> Priority: Minor
>
> At the page:
> https://kafka.apache.org/documentation/
> There is a sentence:
> {{Kafka supports GZIP, Snappy and LZ4 compression protocols. More details on
> compression can be found here.}}
> Especially link under the word *here* is describing very old compression
> settings, which is false in case of version 0.11.x.y.
> JAVA API:
> Also it would be nice to clearly state if *compression.type* uses only case
> sensitive String as a value or if it is recommended to use e.g.
> {{CompressionType.GZIP.name}} for JAVA API.
