Alex Deparvu commented on CASSANDRA-14775:
------------------------------------------
Tried to add a property-based test to this class and came up with [0], still
pretty rough.
it might be an issue of the test value generator, but I got stuck on one
integer overflow in DataHolder#merge.
I separated the failing test in a dedicated test for easier checking, values it
tries to merge are:
* p1: 120, v1: 4263
* p2: 180, v2: 2147479385
* result is -179
Nothing in the direction of a fix, wanted to check if the test approach is ok
first.

> This may be unlikely, but is certainly not impossible. In this event, the
> count for the bucket will be reset to zero, and the time distorted to 1s in
> the future. If MAX_DELETION_TIME were encountered through overflow, this
> might result in a bucket with NO_DELETION_TIME.
