hangc0276 opened a new pull request #3068: URL: https://github.com/apache/bookkeeper/pull/3068
### Motivation We provide some concurrent maps and sets for specific usage, and provide size() and capacity() interface for user to get the real item number and the max item number. However, if user want to monitor how much memory those current maps and set allocated, there is not interface to expose this metric. ### Changes Add `sizeInBytes()` interface to expose the memory size has been allocated for those concurrent maps and sets. -- This is an automated message from the Apache Git Service.
