Settings at cluster level: retention and cleanup policy

[Nicolas MOTTE <ni...@amadeus.com>]

Hi everyone,

Is there any reason why retention and cleanup policy are defined at cluster level and not topic level?
I can t see why it would not be possible from a technical point of view...

Cheers
Nico

Hi Nico,

They can be defined at both cluster and topics levels. Refer https://kafka.apache.org/documentation/#topic-config for topic-level overrides available.

Cheers!

Actually they can be at topic level configs as well. If they are not
defined then the server level configs are used. From Apache Kafka doc:

"The server's default configuration for this property is given under the
Server Default Property heading. A given server default config value only
applies to a topic if it does not have an explicit topic config override."
