Re: [Pytables-users] Faster Performance: A set of nodes vs A new column that ranges within a set?

to access the data across the datasets (for aggregating or calculating averages) you can take a MapReduce approach which should work very well with this approach. On Tue, Jul 17, 2012 at 11:55 PM, Jacob Bennett jacob.bennet...@gmail.com wrote: Thanks for the input Anthony! -Jake On Tue
