> CREATE VIEW followup: derive dependencies on underlying base table
> partitions from view definition
> ---------------------------------------------------------------------------------------------------
>
> Key: HIVE-1079
> URL: https://issues.apache.org/jira/browse/HIVE-1079
> Project: Hive
> Issue Type: Improvement
> Components: Query Processor
> Affects Versions: 0.6.0
> Reporter: John Sichi
> Assignee: Prajakta Kalmegh
>
> When querying a view, it would be useful to know which underlying base table
> partitions it depends on in order to know how fresh the result is (or to be
> able to wait until all of those partitions have been loaded consistently).
> The task is to come up with a way to perform this analysis automatically
> (possibly overconservatively), or alternately to let the view creator
> annotate the view definition with this dependency information, or some
> combination of the two.
> Note that this would be useful for any complex query which directly accesses
> base tables (not just view definitions).
