@mrhhsg Hi, can you help check the changes as below, involved from your
commits recently, which will lead to the function pushdown not work in this PR
in vectorized mode.
BTW, the pushdown function of like / not like can got 2x performance gain in
vectorized execution engine.
```
bool SegmentIterator::_can_evaluated_by_vectorized(ColumnPredicate*
predicate) {
auto cid = predicate->column_id();
FieldType field_type = _schema.column(cid)->type();
switch (predicate->type()) {
case PredicateType::EQ:
case PredicateType::NE:
case PredicateType::LE:
case PredicateType::LT:
case PredicateType::GE:
case PredicateType::GT: {
if (field_type == OLAP_FIELD_TYPE_VARCHAR || field_type ==
OLAP_FIELD_TYPE_CHAR ||
field_type == OLAP_FIELD_TYPE_STRING) {
return config::enable_low_cardinality_optimize &&
_column_iterators[cid]->is_all_dict_encoding();
} else if (field_type == OLAP_FIELD_TYPE_DECIMAL) {
return false;
}
return true;
}
default:
return false;
}
}
```
