> I'm using poor a poor man's method for sampling. In the following table, I

> {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 |
> +-----------+

> 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;
