Examples with RelTraitDef org.apache.calcite.plan.RelTraitDef used on opensource projects

Example 1 with RelTraitDef

use of org.apache.calcite.plan.RelTraitDef in project calcite by apache.

the class VolcanoPlanner method changeTraitsUsingConverters.

private RelNode changeTraitsUsingConverters(RelNode rel, RelTraitSet toTraits, boolean allowAbstractConverters) {
    final RelTraitSet fromTraits = rel.getTraitSet();

    // would typically come after a distribution trait since distribution
    // destroys collation; so when doing the conversion below we use
    // fromTraits as the trait of the just previously converted RelNode.
    // Also, toTraits may have fewer traits than fromTraits, excess traits
    // will be left as is.  Finally, any null entries in toTraits are
    // ignored.
    RelNode converted = rel;
