Benedict commented on CASSANDRA-6689:
-------------------------------------
Whilst it would be nice to depend on an external project here, it doesn't
resolve the problem that it's heavier-weight on heap than what we can achieve
ourselves is. In CASSANDRA-6694 we really try to push the heap overhead to its
minimum, and every byte counts; also, we need an extra field we can manipulate
for maintaining the allocation list for GC, when we come to introduce it. So we
really do need control of it, otherwise we'll only get us as far as step 1.
