merlimat commented on issue #4987: Trim deleted entries after recover cursor. URL: https://github.com/apache/pulsar/pull/4987#issuecomment-524950223 @codelipenghui > While broker recover a cursor, broker will dispatch all messages after the last mark delete entry, so if user has an early position not acked, broker will dispatch so many messages which is already acked by consumer. The description is not accurate. The recovered cursor already has the marked individually deleted messages ranges. There is a max set on how many "ranges" to keep (for limiting the amount of memory). Messages that were marked for deletion before the recovery are not being replayed.
