sure. But a large enterprise cluster will have 10s of racks and will not want a
replica on every rack due to cost concerns.
that should be possible I think.
say, you have 4 racks/groups/tiers ... A, B, C, D
with config...
```
"tieredReplicants": {
"A": 1,
"B" : 2
}
```
number of replicants != number of tiers , and not every replica is on each
tier.
or maybe I misunderstood above statement.
> And trying to automatically generate load rules that properly balance
datasources across those groups by selecting tiers would be burdensome and
likely hard to do well.
Yeah, things could possibly be simplified but use of tiers does let you
achieve the end goal. Just wanted to point out the existing alternative and
also, if possible, it would be nice if tier based grouping could be enhanced to
take care of additional use cases or simplification instead of introducing
another way of grouping historical.
