Re: Hector counter question
Thanks. But the increment is thread safe right? if I have two threads trying to increment a counter, then they won't step on each other toe? *Tamar Fraenkel * Senior Software Engineer, TOK Media [image: Inline image 1] ta...@tok-media.com Tel: +972 2 6409736 Mob: +972 54 8356490 Fax: +972 2 5612956 On Mon, Mar 19, 2012 at 9:05 PM, Jeremiah Jordan jeremiah.jor...@morningstar.com wrote: No, Cassandra doesn't support atomic counters.

That's right - you can have many threads incrementing the same counter and it's safe. But reading and incrementing is unsafe. Richard. -- Richard Low Acunu | http://www.acunu.com | @acunu
