> I'm using poor a poor man's method for sampling. In the following table, I write a non-null
value to COLB with a probability of 0.001.
> {code}
> create table test (mykey integer not null primary key, A.COLA integer, B.COLB integer)
IMMUTABLE_ROWS=true, STORE_NULL=false, IMMUTABLE_STORAGE_SCHEME = ONE_CELL_PER_COLUMN, DISABLE_WAL=true
> {code}
> Then: 
> {code}
> 0: jdbc:phoenix:localhost> select count(*) from test;
> +-----------+
> | COUNT(1)  |
> +-----------+
> | 10000000  |
> +-----------+
> 1 row selected (8.95 seconds)
> 0: jdbc:phoenix:localhost> select count(*) from test where B.COLB is not null;
> +-----------+
> | COUNT(1)  |
> +-----------+
> | 10054     |
> +-----------+
> 1 row selected (0.023 seconds)
> 0: jdbc:phoenix:localhost> select count(*) from test where B.COLB is null;
> +-----------+
> | COUNT(1)  |
> +-----------+
> | 0         |
> +-----------+
> 1 row selected (0.022 seconds)
> {code}
> Last statement should have returned 10000000-10054 = 9989946 rows.
