stack updated HBASE-3484:
-------------------------
Priority: Critical (was: Major)
Upping this to critical. It keeps coming up as an issue.
> Replace memstore's ConcurrentSkipListMap with our own implementation
> --------------------------------------------------------------------
>
> Key: HBASE-3484
> URL: https://issues.apache.org/jira/browse/HBASE-3484
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.92.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Critical
> Fix For: 0.92.0
>
>
> By copy-pasting ConcurrentSkipListMap into HBase we can make two improvements
> to it for our use case in MemStore:
> - add an iterator.replace() method which should allow us to do upsert much
> more cheaply
> - implement a Set directly without having to do Map<KeyValue,KeyValue> to
> save one reference per entry
> It turns out CSLM is in public domain from its development as part of JSR
> 166, so we should be OK with licenses.
