Subject Re: Custom Affinity Functions proposed for removal?
Date Mon, 02 Nov 2020 18:45:25 GMT
We also use custom affinity functions (vis the C# client).

The wish list mentions use of a particular annotation
Is the wish to remove just this annotation, or the ability to define custom
affinity functions at all?

In our case we use affinity functions to ensure particular distribution of
spatial data across a processing cluster to ensure even load management.
