You configure CDCR by _collection_, so this question really makes no sense.
You’d never mention collection.configName. So what I suspect is that you’re
misreading the docs.
<lst name="replica">
<str name="zkHost">${targetZkHost1},${targetZkHost2},${targetZkHost3}</str>
<str name="source">sourceCollection_on_local_cluster</str>
<str name="target">targetCollection_on_targetZkHost1 2 and 3</str>
</lst>
“Turning off CDCR” selective for ZooKeeper instances really makes no sense as
the
point of ZK ensembles is to keep running even if one goes away.
So can you rephrase the question? Or state the problem you’re trying to solve
another way?
Best,
Erick
