Advantage of new union remote?

mergerfs allows “random” selection of branches for search-type actions.
i.e., access, getattr, getxattr, ioctl, listxattr, open, readlink

In theory, this would allow a user to:

  1. create three rclone remotes, each authenticating with a different account;
  2. pool them together with mergerfs, using category.search=rand;
  3. and have most Read-Only API calls spread among the three accounts’ API quotas

If successful, this could effectively triple the standard API quota, and thus triple rclone performance in an API-bottleneck situation.

Is this possible with the rclone Union remote?

N.B. it’s not even clear that this would work properly with mergerfs, but maybe it could work with rclone Union.

Thank you for your attention and hard work! :smiley:
