Subject [jira] [Commented] (CASSANDRA-7919) Change timestamp representation to timeuuid
Date Sat, 13 Sep 2014 04:34:33 GMT


Benedict commented on CASSANDRA-7919:

Are they really used that widely in use cases that aren't server generated? Also, they're
generated considerably less frequently than we will be generating them if we switch to all
updates requiring them, so the attack vector increases.

For RAMP transactions, I'm pretty sure the conflict becomes more dangerous as well. It's a
while since I thought about them, but I remember reaching the conclusion that collisions would
have more severe consequences.

Either way, I still think they're a a very bad idea based on my concerns about storage implications.
