Gopal V updated HIVE-10175:
---------------------------
Component/s: (was: Query Planning)
Physical Optimizer
> PartitionPruning lacks a fast-path exit for large IN() queries
> --------------------------------------------------------------
>
> Key: HIVE-10175
> URL: https://issues.apache.org/jira/browse/HIVE-10175
> Project: Hive
> Issue Type: Bug
> Components: Physical Optimizer, Tez
> Affects Versions: 1.2.0
> Reporter: Gopal V
> Priority: Minor
>
> TezCompiler::runDynamicPartitionPruning() & ppr.PartitionPruner() calls the
> graph walker even if all tables provided to the optimizer are unpartitioned
> (or temporary) tables.
> This makes it extremely slow as it will walk & inspect a large/complex
> FilterOperator later in the pipeline.
