I'm not exactly sure yet. My goal was to not have the shards be too large so as to be un-manageable. In theory - I could just have had 63 (or 64) huge shards - and 1 worker per K8s node, but I haven't tried it.
There are so many variables to try - it is a little overwhelming...
Would be interesting to test. I’m thinking there may not be a benefit to having so many workers on a vm instead of just the entire vm resources as a single worker. Could be wrong, but that would be a bit surprising.
