mcvsubbu opened a new issue #3610: Retention of files in Deleted_Segments does not work correctly URL: https://github.com/apache/incubator-pinot/issues/3610 With a recent re-factor we moved direct calls to file system to be calls via PinotFS in SegmentDeletionManager. Used to be that when segments are deleted, we copied the files from old location to the corresponding location in Deleted_Segments. Files are retained out of Deleted_Segments when they are there for some (configured) period of time. With the re-factor, the copy operation has changed to a 'move' operation. This retains the mod-time on the file. So, we need to implement a 'touch' operation on pinotFS (or, use the copy and delete operation like before) so that access time is updated for the deleted segment files.
