predicate queries (was: bitmap slices)

2010-02-01 Thread Ted Zlatanov
My list of things I need for predicate queries across column and supercolumn names: - bitmask (OR AND1 AND2 AND3 ...). This would make my life easier and take load off our Cassandra servers. Currently I have to scan the result sets on the client side to find the things I need. - date matchi

So it turns out it's not socket related and it seems to only happen on my second new node only not the first one with a higher load. I decommissioned the new node and replaced it with another new node from scratch but the issue persists: clients continue to timeout on it and eventual the node beco

I don't think this is very useful for column names. I could see it being useful for values but if we're going to add predicate queries then I'd rather do something more general. 2010/2/1 Ted Zlatanov : > On Mon, 1 Feb 2010 09:42:16 -0600 Jonathan Ellis wrote: > > JE> 2010/2/1 Ted Zlatanov : >>>
