Re: 0.7 source code

ya, trunk is 0.7...just update the version in the build.xml for your local build and just set it to 0.7-local or something...I think by default the build.xml is behind the times with what the trunk actually is cheers, jesse -- jesse mcconnell jesse.mcconn...@gmail.com On Sun, Jul 4, 2010 at

Re: Help with MapReduce

most likely means that the count() operation is taking too long for the configured RPCTimeout counts get unreliable after a certain number of columns under a key in my experience jesse -- jesse mcconnell jesse.mcconn...@gmail.com On Mon, Apr 19, 2010 at 19:12, Joost Ouwerkerk wrote: >

Re: Limit on number of columns

ry allocated to cassandra there is a limit currently...hopefully gone in 0.7 I will note that another issue I run across with this is that get_count will not return within the rpc timeout after you get a certain amount of columns in there. cheers, jesse -- jesse mcconnell jesse.mcconn...@gmail.com

Re: Issue with TimeUUID

imo it is a terrible bug.. the usage of a TimeUUIDType implies that your actually caring about the unique bits outside of a timestamp... currently it's nothing more then LongType ColumnFamily backed by System.currentTimeInMillis() as a source for name columns. jesse -- jesse mcco
