Hi,

I will be grateful if someone can answer the following questions on Kafka.  

1. What is inter.broker.protocol.version and what it does.

2. What is log.message.format.version and what is does

3. How log.message.format and inter.broker.protocol relate each other.

4. When and on what basis need to the change log.message.format and inter.broker.protocol version.

5. What changes are required on consumer and producer side after changed the version.

Thanks,

Nilesh
