@jerrypeng @merlimat I think this should be a flag to allow people to choose whether to include readers for backlog quota consideration or not. The behavior of a non-durable cursor reading a managed ledger should be close to the behavior of a file reader reading a file in the filesystem. If a reader is actively reading a file, the file is still accessible even it is deleted. If there is a reader active in the manager ledger, the data shouldn't be deleted if the reader hasn't read it. Otherwise, it is a violation of the correctness of a "distributed log". Thus, this behavior shouldn't be changed by default. If there is a requirement of excluding readers from backlog consideration, we should use a setting to let people opt-in this feature. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
