Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	HiveFilterJoinRule.HiveFilterJoinMergeRule Rule that tries to push filter expressions into a join condition and into the inputs of the join.
static class	HiveFilterJoinRule.HiveFilterJoinTransposeRule
static class	HiveFilterJoinRule.HiveFilterNonFilteringJoinMergeRule Rule that tries to push filter expressions into a join condition and into the inputs of the join, iff the join is a column appending non-filtering join.

Constructor Detail

HiveFilterJoinRule

protected HiveFilterJoinRule(org.apache.calcite.plan.RelOptRuleOperand operand,
                             String id,
                             boolean smart,
                             org.apache.calcite.tools.RelBuilderFactory relBuilderFactory)

Creates a PushFilterPastJoinRule with an explicit root operand.

Method Detail

perform

protected void perform(org.apache.calcite.plan.RelOptRuleCall call,
                       org.apache.calcite.rel.core.Filter filter,
                       org.apache.calcite.rel.core.Join join)

Perform is duplicated from parent class to be able to call the modified classify filters. The modified classify method can push filter conditions that refer only to the SJ right input to the corresponding input (the fix is in the number of fields for the join, which is inferred from the join in the original method rather than the concatenation of the join inputs). TODO: Remove this method once RelOptUtil.classifyFilters(org.apache.calcite.rel.RelNode, java.util.List<org.apache.calcite.rex.RexNode>, org.apache.calcite.rel.core.JoinRelType, boolean, boolean, boolean, java.util.List<org.apache.calcite.rex.RexNode>, java.util.List<org.apache.calcite.rex.RexNode>, java.util.List<org.apache.calcite.rex.RexNode>) is fixed.
