Subject Performance issues with CQL3 collections?
Date Wed, 26 Jun 2013 08:26:01 GMT
Hi,

I've seen a couple of people on Stack Overflow having problems with
performance when they have maps that they continuously update, and in
hindsight I think I might have run into the same problem myself (but I
didn't suspect it as the reason and designed differently and by accident
didn't use maps anymore).

Is there any reason that maps (or lists or sets) in particular would become
a performance issue when they're heavily modified? As I've understood them
they're not special, and shouldn't be any different performance wise than
overwriting regular columns. Is there something different going on that I'm
missing?

Here are the Stack Overflow questions:
