gaoran10 opened a new pull request, #24431: URL: https://github.com/apache/pulsar/pull/24431
### Motivation Currently, if the broker wants to determine the valid batch index in a compacted entry, it can only calculate it by examining the compactedOut flag in SingleMessageMetadata. Pulsar supports different protocols, if other protocols doesn't add SingleMessageMetadata for each message in a batch, such as Kafka protocol handler may build the payload in Kafka format. ### Modifications Provide a way to retrieve the retained message count from MessageMetadata. ### Does this pull request potentially affect one of the following parts: <!-- DO NOT REMOVE THIS SECTION.
