> > The physical deletion is not happened when you send a request to delete the data, it also happened in Compaction. When you delete some data, it may generate a .mods file in your data directory to record which record is deleted so that the speed of deletion is fast. > > I checked the data directory to confirm that the relevant .mods files were generated, but after a few days, the .mods files still exist and the space has not been released. Do I need to manually clean up the .mods files? These files will be deleted by compaction thread and you should not delete them manually. However, the compaction may not happen when some conditions are not reached to reduce the waste of system resources. -- This is an automated message from the Apache Git Service.
