--------------------------------------
Summary: Do not permit zstd use until
inter.broker.protocol.version is updated to 2.1
Key: KAFKA-7920
URL: https://issues.apache.org/jira/browse/KAFKA-7920
Project: Kafka
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Jason Gustafson
After brokers have been upgraded to 2.1, users can begin using zstd
compression. Regardless of the inter.broker.protocol.version, the broker will
happily accept zstd-compressed data as long as the right produce request
version is used. However, if the inter.broker.protocol.version is set to 2.0 or
below, then followers will not be able to use the minimum required fetch
version, which will result in the following error:
{code}
[2019-02-11 17:42:47,116] ERROR [ReplicaFetcher replicaId=2, leaderId=1,
fetcherId=0] Error for partition foo-0 at offset 0
(kafka.server.ReplicaFetcherThread)
org.apache.kafka.common.errors.UnsupportedCompressionTypeException: The
requesting client does not support the compression type of given partition.
{code}
We should make produce request validation consistent. Until the
inter.broker.protocol.version is at 2.1 or later, we should reject produce
requests with UNSUPPORTED_COMPRESSION_TYPE.
