| <div class="block">Utility to infer Predicates that are applicable above a RelNode. |
| |
| <p>This is currently used by |
| <a href="../rules/JoinPushTransitivePredicatesRule.html" title="class in org.apache.calcite.rel.rules"><code>JoinPushTransitivePredicatesRule</code></a> to |
| infer <em>Predicates</em> that can be inferred from one side of a Join |
| to the other. |
| |
| <p>The PullUp Strategy is sound but not complete. Here are some of the |
| limitations: |
| <ol> |
| |
| <li> For Aggregations we only PullUp predicates that only contain |
| Grouping Keys. This can be extended to infer predicates on Aggregation |
| expressions from expressions on the aggregated columns. For e.g. |
| <pre> |
| select a, max(b) from R1 where b > 7 |
| → max(b) > 7 or max(b) is null |
| </pre> |
| |
| <li> For Projections we only look at columns that are projected without |
| any function applied. So: |
| <pre> |
| select a from R1 where a > 7 |
| → "a > 7" is pulled up from the Projection. |
| select a + 1 from R1 where a + 1 > 7 |
| → "a + 1 gt; 7" is not pulled up |
| </pre> |
| |
| <li> There are several restrictions on Joins: |
| <ul> |
| <li> We only pullUp inferred predicates for now. Pulling up existing |
| predicates causes an explosion of duplicates. The existing predicates |
| are pushed back down as new predicates. Once we have rules to eliminate |
| duplicate Filter conditions, we should pullUp all predicates. |
| |
| <li> For Left Outer: we infer new predicates from the left and set them |
| as applicable on the Right side. No predicates are pulledUp. |
| |
| <li> Right Outer Joins are handled in an analogous manner. |
| |
| <li> For Full Outer Joins no predicates are pulledUp or inferred. |
| </ul> |
| </ol></div> |
