RFC: Hash prefix considerations for HBase row key design when storing time series data

Hi,

 I have put down some thoughts on designing hash prefixes for HBase
row key in below link.

https://tmblr.co/Z4Ek8e2KYFB0h

Request the community to kindly take a look and share your comments.

TL;DR version - In specific HBase tables (where data is stored by time
series e.g. by day or month) with row key prefixed with a hash, it
might be beneficial to limit the number of hash bits to avoid write
performance impact.

Thanks,
Sreeram
