-------------------------------------------------------------------
Just to follow up on this, it looks like what [~szymon.miezal] and [~blambov]
were talking about (CASSANDRA-20351) has been added to the 5.0.5 release.
[~andersonr] have you been able to reproduce this on a more recent version of
5.0?
was (Author: jeromatron):
Just to follow up on this, [~blambov] did that port make it in, the one you
mentioned about memory-mapped index over a partition index file larger that 2
GB?
[~andersonr] have you been able to reproduce this on a more recent version of
5.0?
