Aleksey Yeschenko created CASSANDRA-7796:
--------------------------------------------
Summary: Stop inheriting liveRatio/computedAt from previous
memtables
Key: CASSANDRA-7796
URL: https://issues.apache.org/jira/browse/CASSANDRA-7796
Project: Cassandra
Issue Type: Bug
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
Priority: Minor
Fix For: 2.0.10
Attachments: 7796.txt
CASSANDRA-6945 helped to reduce the risk of calculating an outlier liveRatio
value, and having to stick with it for a long time, by making liveRatio
per-memtable and not per-cf.
The added optimization of inheriting liveRatio/calculatedAt to minimize
recalculations, however, took us a step back to before CASSANDRA-6945.
I suggest we get rid of inheriting the old values altogether, but reduce the
rate of recalculation by demanding 10x increase in ops to trigger recalc,
instead of the previous 2x.
