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: Hadoop Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 0.6.0
Reporter: John Sichi
Assignee: John Sichi
Fix For: 0.6.0
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).
