Example 1 with ReferencedFields

use of com.apple.foundationdb.record.query.plan.temp.ReferencedFieldsAttribute.ReferencedFields in project fdb-record-layer by FoundationDB.

the class PushReferencedFieldsThroughDistinctRule method onMatch.

@Override
public void onMatch(@Nonnull PlannerRuleCall call) {
    final PlannerBindings bindings = call.getBindings();
    final ExpressionRef<? extends RelationalExpression> lowerRef = bindings.get(lowerRefMatcher);
    final Optional<ReferencedFields> referencedFieldsOptional = call.getInterestingProperty(ReferencedFieldsAttribute.REFERENCED_FIELDS);
    if (!referencedFieldsOptional.isPresent()) {
        return;
    }
    call.pushRequirement(lowerRef, ReferencedFieldsAttribute.REFERENCED_FIELDS, referencedFieldsOptional.get());
}

Example 2 with ReferencedFields

use of com.apple.foundationdb.record.query.plan.temp.ReferencedFieldsAttribute.ReferencedFields in project fdb-record-layer by FoundationDB.

    final ImmutableSet<FieldValue> allReferencedValues = ImmutableSet.<FieldValue>builder().addAll(call.getInterestingProperty(ReferencedFieldsAttribute.REFERENCED_FIELDS).map(ReferencedFields::getReferencedFieldValues).orElse(ImmutableSet.of())).addAll(fieldValuesFromPredicates).addAll(fieldValuesFromResultValues).build();
    call.pushRequirement(lowerRef, ReferencedFieldsAttribute.REFERENCED_FIELDS, new ReferencedFields(allReferencedValues));
}
