congbobo184 opened a new pull request, #16927:
URL: https://github.com/apache/pulsar/pull/16927
### Motivation
now transaction pending ack delete pending ack state position use cursor
mark delete position.
now the logic is use foreach, every position in pending ack state need to
check the position whether smaller than mark delete position. If the position
is smaller than mark delete position, it can be deleted from the pending ack
state map.
this map is a skipListMap, the key is the position, so we only need to check
if the first entry is better, if it is smaller than mark delete we can continue
check, otherwise, we only break the check directly.
