[ https://issues.apache.org/jira/browse/HIVE-8907?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ashutosh Chauhan updated HIVE-8907:
-----------------------------------
Fix Version/s: (was: 0.14.0)
> Partition Condition Remover doesn't remove conditions involving cast on partition column
> ----------------------------------------------------------------------------------------
>
> Key: HIVE-8907
> URL: https://issues.apache.org/jira/browse/HIVE-8907
> Project: Hive
> Issue Type: Improvement
> Components: Logical Optimizer
> Reporter: Ashutosh Chauhan
>
> e.g,
> {code}
> create table partition_test_partitioned(key string, value string) partitioned by (dt string)
> explain select * from partition_test_partitioned where cast(dt as double) >=100.0 and cast(dt as double) <= 102.0
> {code}
> For queries like above, although {{PartitionPruner}} is able to prune partitions correctly, filter is still not optimized away by PCR, where it could.
