Subject [jira] [Commented] (CASSANDRA-6553) Benchmark counter improvements (counters++)
Date Fri, 04 Apr 2014 19:59:23 GMT


Russ Hatch commented on CASSANDRA-6553:

[~iamaleksey] -- here you go:

btw, if you want to change the top title or legend information for better presentation, you
can update the json. Clicking a legend will disable/enable that dataset.
If you want to make changes but don't want to push them to github, you can clone the cassandra_performance
repo and run it locally from the 'graph' directory with python -m SimpleHTTPServer

> Benchmark the difference in performance between CASSANDRA-6504 and trunk.
> * Updating totally unrelated counters (different partitions)
> * Updating the same counters a lot (same cells in the same partition)
> * Different cells in the same few partitions (hot counter partition)
> benchmark:
(old counters)
> compared to:
(new counters)
> So far, the above changes should only affect the write path.
