Hi Arthur, Each salt bucket results in a single region by default. You'll probably want to have more than one region per region server, although this can depend on a number of things. There's some good information on choosing the appropriate number of regions here: http://hbase.apache.org/book/regions.arch.html
In any case, you'll want at least 5 buckets if you're working with 5 nodes, and it's a good idea to work in multiples of 5 (i.e. 5, 10, 15, or 20) if you want to distribute the data relatively evenly over your cluster. - Gabriel On Thu, Oct 9, 2014 at 9:06 AM, [email protected] <[email protected]> wrote: > Hi, > > I plan to use Phoenix to load in a very large transaction detail table (about > 1TB), my HBASE cluster has 5 nodes, I plan to create a SALTED TABLE for it. > > 2 questions: > Q1) Can anyone suggest how to determine the proper value for SALT_BUCKETS? > Q2) In my case here, if I set SALT_BUCKETS = 5 (same number of HBase node), > is it a proper setting? > > Regards > Arthur > > > >
