On the order of a kilobyte, or less, per key segment is probably ideal. Beyond that, you may want to experiment to see what works for you.
Up to the order of a megabyte may work fine in newer versions (at least 1.4), but I'd start having concerns about your schema decisions after that, even if your performance was fine... since ultimately, Accumulo tables are a sorted index, and I'd wonder what kind of index needs such large keys. I suspect a few hundred bytes is probably plenty for most applications. -- Christopher L Tubbs II http://gravatar.com/ctubbsii On Sat, Jan 25, 2014 at 9:06 AM, Jamie Johnson <[email protected]> wrote: > I've read that in HBase there is a recommended limit on key lengths because > they're passed around quite a bit.
