Hemanth Yamijala commented on ATLAS-528: ---------------------------------------- +1 for ATLAS_528.2.patch > support drop table, view > ------------------------ > > Key: ATLAS-528 > URL: https://issues.apache.org/jira/browse/ATLAS-528 > Project: Atlas > Issue Type: Sub-task > Affects Versions: 0.7-incubating > Reporter: Suma Shivaprasad > Assignee: Suma Shivaprasad > Fix For: 0.7-incubating > > Attachments: ATLAS-528.1.patch, ATLAS-528.patch, ATLAS_528.2.patch > > > Drop table and view requires soft deletes. The reason is whenever a table is > dropped , it also may have an associated lineage which consists of a > hive_process which N input tables and an output table. If the table is > dropped, the lineage edge is also dropped resulting in incorrect lineage > history. > With soft deletes, the expected behaviour is to changes the table status to > "deleted" and when the table is recreated through a create table statement, > then create another vertex/entity for that table with the new state. Also, > the lineage for this newly recreated table should be a new hive_process and > should not reuse the existing entity/vertex even though the hive statement > for that process is the same. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
