Tyler Hobbs updated CASSANDRA-5746:
---
Attachment: 0002-Report-created-hint-count-by-endpoint.patch
0001-Remove-HHOM.countPendingHints.patch
0001 removes countPendingHints().
0002 adds a per-endpoint count through the new metrics system. I made
HHOM.hintFor() non-static, as I couldn't see why the singleton couldn't be
used. Let me know if there was some motivation for that.
> HHOM.countPendingHints is a trap for the unwary

> countPendingHints can OOM the server fairly easily since it does a per-target
> seq scan without paging.
> More generally, countPendingHints is far too slow to be useful for routine
> monitoring.
