Windows: remove mmap'ed I/O for index files and force standard file access

    XMLWordPrintableJSON

Details

    Description

      Memory-mapped I/O on Windows causes issues with hard-links; we're unable to delete hard-links to open files with memory-mapped segments even using nio. We'll need to push for close to performance parity between mmap'ed I/O and buffered going forward as the buffered / compressed path offers other benefits.
