Jonathan Ellis updated CASSANDRA-3390:
--------------------------------------
Attachment: 3390.txt
It looks like the culprit is this part:
{code}
if (sliceFilter.count >= cached.getColumnCount())
{code}
... then we don't clone the cached CF. But this is broken as-written; it's
possible for new columns to be inserted, increasing the cached's row size after
the check.
I think the right thing to do here is jut get rid of this special case. We
could try to preserve it by only skipping thie copy when the requested count ==
MAXINT, but that's contrary to best-practices (we strongly discourage using
MAXINT as the limit).
> ReadResponseSerializer.serializedSize() calculation is wrong
