However, this optimization violates the constraint that adding nodes to a plan will never change its analyzed form and thus breaks caching. Instead of doing early optimization, in this PR I just fix some low-hanging slowness in the analyzer. In particular, I add a mechanism for skipping already analyzed subplans, `resolveOperators` and `resolveExpression`. Since trees are generally immutable after construction, it's safe to annotate a plan as already analyzed as any transformation will create a new tree with this bit no longer set. Together these result in a faster analyzer than before, even with added timing instrumentation. ``` Original Code [info] 3430ms [info] 2205ms [info] 1973ms [info] 1982ms [info] 1916ms Without Project Collapsing in DataFrame [info] 44610ms [info] 45977ms [info] 46423ms [info] 46306ms [info] 54723ms With analyzer optimizations [info] 6394ms [info] 4630ms [info] 4388ms [info] 4093ms [info] 4113ms With resolveOperators [info] 2495ms [info] 1380ms [info] 1685ms [info] 1414ms [info] 1240ms ``` Author: Michael Armbrust Closes #7920 from marmbrus/withColumnCache and squashes the following commits: 2145031 [Michael Armbrust] fix hive udfs tests 5a5a525 [Michael Armbrust] remove wrong comment 7a507d5 [Michael Armbrust] style b59d710 [Michael Armbrust] revert small change 1fa5949 [Michael Armbrust] move logic into LogicalPlan, add tests 0e2cb43 [Michael Armbrust] Merge remote-tracking branch 'origin/master' into withColumnCache c926e24 [Michael Armbrust] naming e593a2d [Michael Armbrust] style f5a929e [Michael Armbrust] [SPARK-9141][SQL] Remove project collapsing from DataFrame API 38b1c83 [Michael Armbrust] WIP Project: http://git-wip-us.apache.org/repos/asf/spark/repo Commit: http://git-wip-us.apache.org/repos/asf/spark/commit/23d98220 Tree: http://git-wip-us.apache.org/repos/asf/spark/tree/23d98220 Diff: http://git-wip-us.apache.org/repos/asf/spark/diff/23d98220 Branch: refs/heads/master Commit: 23d982204bb9ef74d3b788a32ce6608116968719 Parents: 34dcf10 Author: Michael Armbrust Authored: Wed Aug 5 09:01:45 2015 -0700 Committer: Yin Huai Committed: Wed Aug 5 09:01:45 2015 -0700 ---------------------------------------------------------------------- .../spark/sql/catalyst/analysis/Analyzer.scala | 28 ++++---- .../sql/catalyst/analysis/CheckAnalysis.scala | 3 + .../catalyst/analysis/HiveTypeCoercion.scala | 30 ++++---- .../spark/sql/catalyst/plans/QueryPlan.scala | 5 +- .../catalyst/plans/logical/LogicalPlan.scala | 51 +++++++++++++- .../spark/sql/catalyst/rules/RuleExecutor.scala | 22 ++++++ .../spark/sql/catalyst/trees/TreeNode.scala | 64 ++++------------- .../sql/catalyst/plans/LogicalPlanSuite.scala | 72 ++++++++++++++++++++ .../scala/org/apache/spark/sql/DataFrame.scala | 6 +- .../apache/spark/sql/execution/SparkPlan.scala | 2 +- .../apache/spark/sql/execution/pythonUDFs.scala | 2 +- .../org/apache/spark/sql/CachedTableSuite.scala | 20 ++++++ .../org/apache/spark/sql/DataFrameSuite.scala | 12 ---- .../hive/execution/HiveCompatibilitySuite.scala | 5 ++ .../spark/sql/hive/HiveMetastoreCatalog.scala | 5 +- .../org/apache/spark/sql/hive/hiveUDFs.scala | 3 +- .../spark/sql/hive/execution/HiveUDFSuite.scala | 8 +-- .../sql/hive/execution/SQLQuerySuite.scala | 2 + 18 files changed, 234 insertions(+), 106 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/spark/blob/23d98220/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala ---------------------------------------------------------------------- diff --git a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala b/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala index ca17f3e..6de31f4 100644 --- a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala +++ b/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala @@ -90,7 +90,7 @@ class Analyzer( */ object CTESubstitution extends Rule[LogicalPlan] { // TODO allow subquery to define CTE - def apply(plan: LogicalPlan): LogicalPlan = plan transform { + def apply(plan: LogicalPlan): LogicalPlan = plan resolveOperators { case With(child, relations) => substituteCTE(child, relations) case other => other } @@ -116,7 +116,7 @@ class Analyzer( * Substitute child plan with WindowSpecDefinitions. */ object WindowsSubstitution extends Rule[LogicalPlan] { - def apply(plan: LogicalPlan): LogicalPlan = plan transform { + def apply(plan: LogicalPlan): LogicalPlan = plan resolveOperators { // Lookup WindowSpecDefinitions.
