-----------------------------
Summary: Add fixed-delay scheduling mode to SCMBlockDeletingService
Key: HDDS-13817
URL: https://issues.apache.org/jira/browse/HDDS-13817
Project: Apache Ozone
Issue Type: Sub-task
Components: SCM
Reporter: ChenXi
Assignee: ChenXi
SCMBlockDeletingService uses BackgroundService to implement periodic task
scheduling.
BackgroundService currently executes at a fixed frequency. If a task takes
longer than the interval, the next task will be executed immediately after the
previous task completes.
For SCMBlockDeletingService, when the deletedBlocks table contains a large
amount of data, the DeletedBlockLogStateManager#getReadOnlyIterator call may
take longer than the BackgroundService's interval. This can cause other
operations, such as DeletedBlockLogImpl#onMessage, to be blocked on the
DeletedBlockLogImpl#lock, resulting transactions status cannot be updated.
