IMPALA-5280: Coalesce chains of OR conditions to an IN predicate This change introduces a new rule to merge disjunct equality predicates into an IN predicate. As with every rule being applied bottom up, the rule merges the leaf OR predicates into an in predicate and subsequently merges the OR predicate to the existing IN predicate It will also merge two compatible IN predicates into a single IN predicate. Patch also addresses review comments to normalize the binary predicates and testcases for the same. binary predicates of the form constant <op> non constant are normalized to non constant <op> constant Change-Id: If02396b752c5497de9a92828c24c8062027dc2e2 --- M fe/src/main/java/org/apache/impala/analysis/Analyzer.java M fe/src/main/java/org/apache/impala/analysis/Expr.java A fe/src/main/java/org/apache/impala/rewrite/EqualityDisjunctsToInRule.java M fe/src/main/java/org/apache/impala/rewrite/NormalizeBinaryPredicatesRule.java M fe/src/test/java/org/apache/impala/analysis/ExprRewriteRulesTest.java 5 files changed, 204 insertions(+), 12 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/10/7110/7 -- To view, visit http://gerrit.cloudera.org:8080/7110 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: If02396b752c5497de9a92828c24c8062027dc2e2 Gerrit-PatchSet: 7 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: sandeep akinapelli <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: sandeep akinapelli <[email protected]>
