Zach Amsden has uploaded a new patch set (#9). Change subject: IMPALA-5003: Constant propagation in scan nodes and inline views ......................................................................
IMPALA-5003: Constant propagation in scan nodes and inline views When conjuncts are pushed into table refs and inline views, they can be considered for constant progagation within that node. In certain cases, we might end up with a FALSE conditional and now we can convert ScanNodes to EmptySet nodes when that occurs. Testing: Expanded the test cases for the planner to achieve constant propagation. Added Kudu, datasource, Hdfs and HBase tests to validate we can create EmptySetNodes Change-Id: I79750a8edb945effee2a519fa3b8192b77042cb4 --- M fe/src/main/java/org/apache/impala/analysis/AnalysisContext.java M fe/src/main/java/org/apache/impala/analysis/Analyzer.java M fe/src/main/java/org/apache/impala/analysis/Expr.java M fe/src/main/java/org/apache/impala/analysis/SelectList.java M fe/src/main/java/org/apache/impala/planner/DataSourceScanNode.java M fe/src/main/java/org/apache/impala/planner/KuduScanNode.java M fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java M fe/src/main/java/org/apache/impala/rewrite/ExprRewriter.java M fe/src/test/java/org/apache/impala/planner/PlannerTest.java M testdata/workloads/functional-planner/queries/PlannerTest/analytic-fns.test M testdata/workloads/functional-planner/queries/PlannerTest/conjunct-ordering.test A testdata/workloads/functional-planner/queries/PlannerTest/constant-propagation.test M testdata/workloads/functional-planner/queries/PlannerTest/data-source-tables.test M testdata/workloads/functional-planner/queries/PlannerTest/hdfs.test M testdata/workloads/functional-planner/queries/PlannerTest/joins.test M testdata/workloads/functional-planner/queries/PlannerTest/kudu.test M testdata/workloads/functional-planner/queries/PlannerTest/subquery-rewrite.test 17 files changed, 462 insertions(+), 86 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/89/6389/9 -- To view, visit http://gerrit.cloudera.org:8080/6389 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I79750a8edb945effee2a519fa3b8192b77042cb4 Gerrit-PatchSet: 9 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Zach Amsden <zams...@cloudera.com> Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Dan Hecht <dhe...@cloudera.com> Gerrit-Reviewer: Marcel Kornacker <mar...@cloudera.com> Gerrit-Reviewer: Zach Amsden <zams...@cloudera.com>
