Subject Re: [VOTE] KIP-516: Topic Identifiers
Date Tue, 13 Oct 2020 21:38:41 GMT
Hi, Justine,

Thanks for starting the vote. Just a few minor comments.

1. It seems that we should remove the topic field from the
StopReplicaResponse below?
StopReplica Response (Version: 4) => error_code [topics]
  error_code => INT16
    topics => topic topic_id* [partitions]

2. "After controller election, upon receiving the result, assign the
metadata topic its unique topic ID". Will the UUID for the metadata topic
be written to the metadata topic itself?

3. The vote request is designed to support multiple topics, each of them
may require a different sentinel ID. Should we reserve more than one
sentinel ID for future usage?

4. UUID.randomUUID(): Could we clarify whether this method returns any
sentinel ID? Also, how do we expect the user to use it?

Thanks,

Jun
