Gopal V reopened HIVE-10175:
----------------------------
Reverting this patch as this needs to cycle-break & fold out the SyntheticJoin
predicates even if the target table is unpartitioned.
> DynamicPartitionPruning 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
> Assignee: Gopal V
> Priority: Minor
> Fix For: 1.3.0, 2.0.0
>
> Attachments: HIVE-10175.1.patch, HIVE-10175.profile.html
>
>
> 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.
