-------------------------------------------
Summary: Support for dynamic table links
Key: HIVE-3096
URL: https://issues.apache.org/jira/browse/HIVE-3096
Project: Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 0.10.0
Reporter: Sambavi Muthukrishnan
Assignee: Sambavi Muthukrishnan
HIVE-2989 introduces the concept of table links. In this improvement, the plan
is to complete the support for dynamic table links.
Dynamic links are a type of link where
a) if the source of the table link adds a partition, that partition is
automatically added to all tables that link to it
b) if the source of the table link drops a partition, that partition is
automatically dropped from all the tables that link to it
c) if the source of the table link has a metadata change via:
ALTER TABLE table CHANGE COLUMN column ...
ALTER TABLE table ADD/REPLACE COLUMN column ...
ALTER TABLE table_name [PARTITION partitionSpec] SET LOCATION "new location"
the links pointing to that table will also have their metadata correspondingly
changed.
