      Hi ,

      When there is a heavy collection say with 50 crore of documents ,

      field - created_at with date value on which TTL with expiration 1 year is applied

      Index is created 100%

      How does the mongodb TTL thread that runs every 60 seconds prepare which set of documents to delete?

      Does it scan complete collection every minute?
