> @danny0405 : going back to your original example in the description. If a file slice was written in C1, and never updated in any of the future commits, at C10 or C11, even if cleaner detects all data files pertaining to C1 to C4 needs to be deleted, latest file slice in C1 will never be touched. Cleaner will always ensure latest file slice for any file group will never be cleaned up. So, can you help understand why we might see FileNotFoundIssue? My description was not that accurate, because the use the Snapshot Isolation, when the reader starts reading the C1 file slice `s1` where it is the latest in the file group at C9, a subsequent C10 then modifies the C1 file slice and the cleaner starts working, the `s1` would be cleaned. -- This is an automated message from the Apache Git Service.
