Laszlo Bodor commented on HIVE-21510:
-------------------------------------
note, an example from
https://issues.apache.org/jira/secure/attachment/12963723/HIVE-21001.45.patch:
vector_date_1.q.out
LongColEqualLongColumn -> VectorUDFAdaptor due to the rewrite
before patch:
{code}
selectExpressions: LongColEqualLongColumn(col 0:date, col 0:date) -> 3:boolean,
LongColNotEqualLongColumn(col 0:date, col 1:date) -> 4:boolean,
LongColLessEqualLongColumn(col 0:date, col 0:date) -> 5:boolean,
LongColLessEqualLongColumn(col 0:date, col 1:date) -> 6:boolean,
LongColLessLongColumn(col 0:date, col 1:date) -> 7:boolean,
LongColGreaterEqualLongColumn(col 1:date, col 1:date) -> 8:boolean,
LongColGreaterEqualLongColumn(col 1:date, col 0:date) -> 9:boolean,
LongColGreaterLongColumn(col 1:date, col 0:date) -> 10:boolean
{code}
after patch:
{code}
selectExpressions: VectorUDFAdaptor((null or dt1 is not null))(children:
IsNotNull(col 0:date) -> 3:boolean) -> 4:boolean, LongColNotEqualLongColumn(col
0:date, col 1:date) -> 5:boolean, LongColLessEqualLongColumn(col 0:date, col
1:date) -> 6:boolean, LongColLessLongColumn(col 0:date, col 1:date) ->
7:boolean, VectorUDFAdaptor((null or dt2 is not null))(children: IsNotNull(col
1:date) -> 8:boolean) -> 9:boolean, LongColGreaterEqualLongColumn(col 1:date,
col 0:date) -> 10:boolean, LongColGreaterLongColumn(col 1:date, col 0:date) ->
11:boolean
{code}
> Vectorization: add support for and/or for (constant,column) cases

> Project: Hive
> Issue Type: Improvement
> Reporter: Zoltan Haindrich
> Assignee: Laszlo Bodor
> Priority: Major
>
> After HIVE-21001 some selectExpressions will start using VectorUDFAdaptor for
> "null and x" expressions. Because right now there are 2-3 places from which
> rewrite will be done to the form of "null and/or x" form; it would be better
> to support it.
