While indexing, is there going to be any performance benefit to set the

using cloudClient.add(solrInputDoc), instead of suing the method
cloudClient.add(collectionName, solrInputDoc)?
Is this performance benefit to consider or is this mere of a convenience /
better looking code?
There should be no detectable performance difference between the two
unless you've got an accurate way to measure microseconds or
nanoseconds. Even then, the difference should be extremely small.
If the code was written smartly, and usually Solr code is written very
well, both will end up being executed by the same final code, it will
just be the source of the collection string that will be different.
