Hello.
I know that FromBuffer/FrozenView methods allow read from MMAP-file.
But how to create such MMAP-file in roaring format: i f my bitmap > RAM? (or if I would like enforce some RAM usage limit)

Currently, there is no external-memory roaring data structure in this project. If you'd like to contribute one, it would be great.

  • or full-featured 'external-memory' data structure
  • or just some writer which can write "append-only" bitmap in frozen format to bufio.Writer
