The lock in MOB is trying to avoid making deleted cells live again. If we always retain the delete markers - until they are expired - in major compaction like what we do now in major compaction when write lock cannot be acquired, the locks are not needed anymore. How do you think about this approach? [~jmhsieh], [~mbertozzi]. was (Author: jingcheng.du@intel.com): Hi [~appy]. The lock in MOB is trying to avoid making deleted cells live again.
