----------------------------------
Summary: Partitioning pruning produces wrong results when there
are nested expressions in the filter
Key: DRILL-3690
URL: https://issues.apache.org/jira/browse/DRILL-3690
Project: Apache Drill
Issue Type: Bug
Reporter: Mehant Baid
Assignee: Mehant Baid
Priority: Blocker
Fix For: 1.2.0
Consider the following query:
select 1 from foo where dir0 not in (1994) and dir1 not in (1995);
The filter condition is: AND(NOT(=($1, 1994)), NOT(=($2, 1995)))
In FindPartitionCondition we rewrite the filter to cherry pick the partition
column conditions so the interpreter can evaluate it, however when the
expression contains more than two levels of nesting (in this case AND(NOT(=)))
) the expression does not get rewritten correctly. In this case the expression
gets rewritten as: AND(=($1, 1994), =($2, 1995)). NOT is missing from the
rewritten expression producing wrong results.
