Andrew Purtell commented on PHOENIX-3218:
-----------------------------------------

bq. HBase is a KV store
This is commonly stated, but isn't quite right. It is more accurate to say 
HBase implements the BigTable data model, described in 
http://static.googleusercontent.com/media/research.google.com/en//archive/bigtable-osdi06.pdf
 . You can stop there, but as to what I mean: "KV store" describes a flat 
keyspace with single key for lookup and does not imply a partitioning scheme. 
In contrast, HBase (and BigTable) presents multiple keyspaces (aka tables) and 
is a distributed ordered tree.
