### Context When publishing messages to a topic, the `sequenceId` param is used for topic message deduplication. In the transaction, when the TC receives commit command, the TC needs to write a commit marker append to the topic partition, the commit marker needs a `sequenceId` to avoid duplication, if the commit marker is duplicated the topic partition cursor will send duplication committed messages to the consumer, or we need to find some other approaches to avoid duplication. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
