Table definition: create table columnTable ( id varchar(36) not null, partitionId integer, numRows integer not null, data blob) For a table with n columns, there will be n+1 region entries. A base entry and one entry each for a column. The data column for the base entry will contain the stats. id for the base entry would be the uuid while for column entries it would be uuid_colName.
