> Use HashedwheelTimer for request timeouts for PCBC

> Key: BOOKKEEPER-756
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-756
> Project: Bookkeeper
> Issue Type: Improvement
> Components: bookkeeper-client
> Reporter: Sijie Guo
> Assignee: Sijie Guo
> Fix For: 4.3.0, 4.2.3

> Attachments: BOOKKEEPER-756.diff

>
> Current scheduler based timeout mechanism is per batch, which isn't
> efficient. HashedWheelTimer is much better for timeouts. So change the PCBC
> to use HashedWheelTimer for timeouts.
> Besides that HashedWheelTimer change, it also provides multiple channel per
> bookie support for latency consideration.
