Subject Re: Kafka - entity-default Vs entity-name
Date Fri, 12 Jun 2020 14:28:17 GMT
Hi Nag,

To address (2) first, the --entity-default flag requests the default
configuration that all brokers inherit. An individual broker may override
any of the default config's entries, which is done by specifying the broker
ID to the --entity-name flag.

The reason you're getting blank output for --entity-default is because all
entries in the config are using their default values. If you wish to see
all config entries, you can pass flag --all which is included in the 2.5
release (KIP-524:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-524%3A+Allow+users+to+choose+config+source+when+describing+configs
).

Please let me know if you have any other questions,

Brian
