Subject Re: Solr cloud schema and schemaless

The schema mode is _per collection_, not per node. So there's no trouble mixing
replicas from collection A running schema model 1 with replicas from
collection B
running a different schema model.

That said, schemaless is _not_ recommended for production unless you have
total control over the ETL chain and can guarantee that documents conform to
some standard. Schemaless does its best, but it guesses based on the
first time it
sees a field. So if the first doc has field X with a value of 1, it
infers that this field
is an int type. If doc2 has a value of 1.0, the doc fails with a parsing error.

FYI,
Erick
