Hi Patrick,
we plan to upgrade next year. Can't do any faster. However, distributed ephemeral pinning was introduced with octopus. It was one of the major new features and is explained in the octopus documentation in detail.
Are you saying that it is actually not implemented?
If so, how much of the documentation can I trust?
If it is implemented, I would like to get it working - if this is possible at all. Would you still take a look at the data?
Best regards,

Octopus is really too old for this. I think it's missing some very
important performance related patches. I suggest you upgrade if you
really want to use this.
