Summary: Improve debugging experience of queries of nested views
Key: IMPALA-11984
URL: https://issues.apache.org/jira/browse/IMPALA-11984
Project: IMPALA
Issue Type: New Feature
Components: Frontend
Reporter: Manish Maheshwari
When debugging queries on views with multiple levels of nesting, we run into
below issues
* We don't have the rewritten query replacing the views. Asking for each of
the view definitions and replacing them in the query is very tedious and manual
task
** Its hard to understand the complexity of the query and recommendations for
optimal rewrites
* We don't have a easy way to list all the tables that participate in the
query
** To check for table and column stats
** to check for table sizes and partitioning
