Yes, don’t use a salt. Salt implies that your seed is orthogonal (read random) to the base table row key. You’re better off using a truncated hash (md5 is fastest) so that at least you can use a single get().
Common? Only if your row key is mostly sequential. Note that even with bucketing, you will still end up with regions only 1/2 full with the only exception being the last region. > On May 1, 2015, at 11:09 AM, jeremy p <athomewithagroove...@gmail.com> wrote: > > Hello all, > > I've been out of the HBase world for a while, and I'm just now jumping back > in. > > As of HBase .94, it was still common to take a hash of your RowKey and use > that to "salt" the beginning of your RowKey to obtain an even distribution > among your region servers.
