Sylvain Lebresne commented on CASSANDRA-2104:
---------------------------------------------
I have a hard time reproducing (using your script). Do you use TimeUUIDType for
the column or the super column names ? (I've tried both though).
I'll continue trying. However, if you happen to have some SSTables that
directly triggers it and that is smaller that the ones you added above, that
would be awesome (I'm struggling making enough room on my laptop for the ones
you attached above :)).
Anyway, thanks for taking time on this, I'll continue to try.
