---------------------------------------
Summary: Materialize sub parts of query that is used in multiple
times in a query
Key: IMPALA-8083
URL: https://issues.apache.org/jira/browse/IMPALA-8083
Project: IMPALA
Issue Type: Improvement
Reporter: Janaki Lahorani
When the same bit of processed data is used in multiple places (within the
query to begin with), it should be materialized. Some use cases are grouping
set queries where one group computation can be derived from other group
computation, with clause, data mining like queries and graph processing
queries. To begin with, the materialized data could be scoped for the query.
But this has the potential to grow to a group of queries.
