Summary: Hive Replication to support "archival" destinations
Key: HIVE-23155
URL: https://issues.apache.org/jira/browse/HIVE-23155
Project: Hive
Issue Type: New Feature
Reporter: Manish Maheshwari
Currently in Hive replication any partitions dropped in the source are also
propagated to the destination. The request here is to support a new destination
type called as "archival" with the following properties
* Partitions deleted on source are not deleted in the target
* Tables deleted on source are not deleted in the target
** When new tables with the same name are added in the source, rename the old
table (s) in the destination with some naming mechanism
* Overwritten partitions on prem / Acid changes on prem etc are should be
allowed to be replicated.
Use case - We are using Hive replication from on prem HDFS to S3 where S3 is an
archive for cold data. We want old data that is deleted on prem does not get
deleted on the cloud.
