> Pre-materializing complex CTE queries
> -------------------------------------

> Key: HIVE-11752
> URL: https://issues.apache.org/jira/browse/HIVE-11752
> Project: Hive
> Issue Type: Improvement
> Components: Query Processor
> Reporter: Navis
> Assignee: Navis
> Priority: Minor
> Attachments: HIVE-11752.03.patch, HIVE-11752.1.patch.txt,

>
> Currently, hive regards CTE clauses as a simple alias to the query block,
> which makes redundant works if it's used multiple times in a query. This
> introduces a reference threshold for pre-materializing the CTE clause as a
> volatile table (which is not exists in any form of metastore and just
> accessible from QB).
