ZhuoYu Chen updated FLINK-24959:
--------------------------------
Description:
BITMAP_AND :{color:#333333}Computes the intersection of two input bitmaps and
returns the new bitmap{color}
{code:java}
select bitmap_count(bitmap_and(to_bitmap(1), to_bitmap(2))) cnt; {code}
{color:#333333} {color}
{color:#333333}{{TO_BITMAP:input for the value of 0 ~ 18446744073709551615
unsigned bigint in the range, the output for the bitmap containing the element.
This function is mainly used for stream load task to import integer fields into
the bitmap field of the table}}{color}
{code:java}
select bitmap_count(to_bitmap(10)); {code}
{color:#30323e}BITMAP_ANDNOT:Computes the set (difference set) that is in A but
not in B.{color}
{code:java}
select bitmap_to_string(bitmap_andnot(bitmap_from_string('1, 3'),
bitmap_from_string('2'))) cnt; {code}
