The ConverterRule is a RelOptRule but with default implementation of onMatch:
public void onMatch(RelOptRuleCall call) {
RelNode rel = call.rel(0);
if (rel.getTraitSet().contains(inTrait)) {
final RelNode converted = convert(rel);
if (converted != null) {
call.transformTo(converted);
}
}
}
So, the first thing is does your ConverterRule matches ?Best, Danny Chan 在 2019年3月12日 +0800 PM4:01，[email protected]，写道： > > ElasticsearchRel.CONVENTION
