[jira] [Updated] (HDDS-15391) Implement deferred Merge Join snapdiff with dependency ordering
[ https://issues.apache.org/jira/browse/HDDS-15391?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Saketa Chalamchala updated HDDS-15391:
--------------------------------------
Description:
Implement a new method that performs deferred `CREATE`/`MODIFY`/`RENAME` classification. It must integrate:
* *Delete Retention:* Pruning descendant deletes using utilities from HDDS-15388
* *Dependency Ordering:* Building the snapdiff dependency graph and performing topological sort from HDDS-15390
* *Conflict Rules:* Handling path conflicts (delete-before-rename, rename-before-create).
Note: Introduce guardrails around dependency ordering.
