Shawn Heisey commented on SOLR-10574:
-------------------------------------
bq. Yes, I wanted it to be true by default (to maintain previous behaviour).
But I don't have any strong opinion either way. What is the consensus here?
Repeating what I said earlier: I think field guessing should be off by default
in basic_configs (or whatever we end up calling it), because (IMHO) it has a
tendency to cause more problems than it solves. While I understand a desire to
maintain default settings from version to version, I believe that strict
adherence to this only applies to new minor releases.
With 7.0, we have an opportunity to review past decisions, decide whether they
are still relevant. I think that every assumption and every default should be
subject to review on every new major version. I expect almost all of them to
be retained after such a review ... massive changes would be a sign that we
were doing a terrible job.
Related tangents: 1) Should we have a classic schema configset, or do we want
to eventually remove the classic factory? 2) Should the filename for the
managed schema regain its .xml extension?

> Currently, the data_driven_schema_configs is the default configset when
> collections are created using the bin/solr script and no configset is
> specified.
> However, that may not be the best choice. We need to decide which is the best
> choice, out of the box, considering many users might create collections
> without knowing about the concept of a configset going forward.
> (See also SOLR-10272)
> Proposed changes:
> # Remove data_driven_schema_configs and basic_configs
> # Introduce a combined configset, {{_default}} based on the above two
> configsets.
> # Build a "toggleable" data driven functionality into {{_default}}
> Usage:
> # Create a collection (using _default configset)
> # Data driven / schemaless functionality is enabled by default; so just start
> indexing your documents.
> # If don't want data driven / schemaless, disable this behaviour: {code}
> curl http://host:8983/solr/coll1/config -d '{"set-user-property":
> {"update.autoCreateFields":"false"}}'
> {code}
> # Create schema fields using schema API, and index documents
