Alex Lourie commented on CASSANDRA-14056:
-----------------------------------------
[~jasobrown] [~mkjellman] Yes, this would still be an issue with the new
dtests. Someone might want to test with the "offheap_objects" configuration
option set. The new dtests supports this with a command-line parameter,
"--use-off-heap-memtables"; as a result, I've updated the patch and opened a PR
at [https://github.com/apache/cassandra-dtest/pull/18.]
Please let me know if you think this is the appropriate solution, and if there
are any problems with the patch.
Thanks!
