--------------------------------------
Summary: Performance Optimizations for deleting large number of
users/groups
Key: RANGER-4246
URL: https://issues.apache.org/jira/browse/RANGER-4246
Project: Ranger
Issue Type: Improvement
Components: Ranger
Affects Versions: 2.4.0
Reporter: Abhishek Kumar
Assignee: Abhishek Kumar
RANGER-4230 includes changes to significantly improve the running time for
user/group deletes when there are large number of users/groups in ranger.
Typically operations like deleting external users/groups are supposed to be
performed in a maintenance window.
However, even after changes in RANGER-4230 go through, in the worst case the
running time can still be in the order of several minutes or may be a few
hours. To further bring down the time to best achievable running times, ranger
db schema changes are required with ON DELETE CASCADE and ON DELETE NULL in the
relevant db tables. This Jira tracks the work regarding the same.
