    Details

      Description

      As discussed on the parent issues, the first implementation (based on memory mapped files) caused some stability issues under memory pressure.

      This issue tracks adding alternative implementations (as discussed on the parent issue)

      • Eagerly write to file and read via memory mapping the file (mode FILE_MMAP)
      • Eagerly write to file and read from file (mode FILE)
      • The existing implementation will be retained as mode MMAP
