Subject [jira] [Commented] (CASSANDRA-6626) Create 2.0->2.1 counter upgrade dtests
Date Mon, 12 May 2014 22:34:15 GMT


Russ Hatch commented on CASSANDRA-6626:

With the recent work on the upgrade tests I changed the counters testing there a little bit.

Now the test creates 100 separate counter cells. These are updated randomly for 15 seconds
(so we'll get sorta even distribution of counts across the 100). Then the counts are read
back and compared to expected values. On some versions I was running into very slow counter
updates which is why I opted for a max time approach instead of a fixed count, though in retrospect
maybe those very slow scenarios are worth investigating more.

[~iamaleksey] does this update seem like reasonable coverage, or should we extend it a bit
more? Let me know if there's any specifics you'd want to see covered in a test.
