lypanov # how can one emulate a range query with riak?
another table with links? is that efficient with mapred?
wondering how to do a new uncached mapred on a historic data set efficiently

benblack # going to be a tough one
doc stores are good at a lot of things, but time series is not really in the sweet spot

lypanov # seems to be the ideal use case for cassandra afaict :(

benblack # column stores are better at it (and not as good at a lot of other things)

lypanov # either way i think riak will keep us going longer than mongo so i'll just go with it.
if we run into issues i'll go with cassandra where needed.
gosh its nice to have so many options but sucks sometimes ;)

benblack # tha gony of choice the agony, even
i would definitely choose riak over mongo for most situations

lypanov # i think riak + cassandra would be serviceable for long term. but mongo in its current 
state just doesn't fill me with certainty about the reliability of the system.
