> Key: HDDS-13962
> URL: https://issues.apache.org/jira/browse/HDDS-13962
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Swaminathan Balachandran
> Assignee: Swaminathan Balachandran
> Priority: Major
> Labels: pull-request-available
>
> Make Bootstrap lock acquire DAGBasedLeveledResourceLock and add
> SNAPSHOT_GC_LOCK, SNAPSHOT_DB_LOCK, SNAPSHOT_DB_CONTENT_LOCK,
> SNAPSHOT_LOCAL_DATA_LOCK as it's children this is to ensure Bootstrap lock is
> never taken in other order to enforce correct lock ordering.
> The OMDBCheckpointServlet implementation has to acquire a full stripe write
> lock to acquire a lock.
> This makes the design also very extensible since adding a service just has to
> acquire a read lock on BOOTSTRAP_LOCK on a key and no need to change anything
> on OmDbCheckpointServlet implementation which makes it foolproof.
