Method Summary

Modifier and Type	Method and Description
boolean	fastBailOut() Whether we should create the rewriting in the minimal subtree of plan operators.
boolean	generateUnionRewriting() Whether to generate rewritings containing union if the query results are contained within the view results.
@Nullable HepProgram	unionRewritingPullProgram() If we generate union rewriting, we might want to pull up projections from the query itself to maximize rewriting opportunities.
