[jira] [Updated] (HDDS-9095) Cleanup expired incomplete MPUs
[ https://issues.apache.org/jira/browse/HDDS-9095?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ivan Andika updated HDDS-9095:
------------------------------
Summary: Cleanup expired incomplete MPUs (was: Implement cleanup service for MultipartInfoTable)
> Cleanup expired incomplete MPUs
> -------------------------------
>
> Key: HDDS-9095
> URL: https://issues.apache.org/jira/browse/HDDS-9095
> Project: Apache Ozone
> Issue Type: Improvement
> Components: OM
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Major
> Fix For: 1.4.0
>
>
> In our cluster, there are around few thousands MPU keys in multipartInfoTable, with some of them being few months old.
> The reason is that these MPU keys are already initiated, and possibly committed few parts, but was not completed / aborted by the user. These spaces can be freed.
> Similar to the cleanup service OM open key table (HDDS-4120), we can implement clean up on MultipartInfoTable (and related open keys in OpenKeyTable) using a background job. -However, instead of using a new OM request / response, we can reuse the OM MPU abort request / response instead, which already handles the cleanup (i.e. expired inflight MPU can be aborted after a defined expiry threshold).-
