Sylvain Lebresne commented on CASSANDRA-3538:
---------------------------------------------
You're right, I meant MIN_VALUE. Patch updated. Turns out I was a bit quick and
my previous patch wasn't passing all unit tests because we already have a test
that verify that we don't purge tombstones when it shouldn't. As for testing
this patch, it's actually tricky because normal query already remove columns
that are shadowed by a tombstones, making it hard to test.
> Remove columns shadowed by a deleted container even when we cannot purge
