Subject Schema design question
Date Sat, 16 Apr 2011 08:27:51 GMT
As I'm about to plan a similar app I have studied the HBase schema of the opentsb project:


The opentsb approach seems to have many rows instead of many columns. What is the better schema
design in terms of query performance? My experience so far is that a width schema with many
columns but less rows performs better. A 'horizontal' table scan seems to be better suited
for fast queries.
