Subject [jira] [Commented] (SOLR-10574) Choose a default configset for Solr 7
Date Thu, 27 Apr 2017 19:58:05 GMT


Jan Høydahl commented on SOLR-10574:

I also hope we could strip down the minimum needed explicit config that still does something
useful. I mean, the {{managed-schema}} for data-driven only defines three fields but is *1044
lines long*! I would hope it could be something like 10 lines... Perhaps the whole set of
default field-types and copy-fields could be included with one new tag e.g. {{<standardFieldTypes/>}},
and the txt files in {{lang}} folder could be loaded as resources from the class path.  Similarly
we don't need to ship currency.xml, elevate.xml, protwords.txt, stopwords.txt and synonyms.txt.
Users can add those, or better, use their managed counterparts.
Similarly {{solrconfig.xml}} for _data_driven_ is *1408 lines long*, which must be very confusing
for new users. Could we do more default and implicit stuff like we did with implicit AdminHandlers?
And perhaps bake the {{add-unknown-fields-to-the-schema}} chain into an implicit feature that
could be toggled during update {{&fieldGuessing=on|off|training}} where in training mode
it would only learn. If someone needed to override the implicit chain they could add a tag
{{<fieldGuessingChain>my-better-chain</fieldGuessingChain>}}. We could probably
have a "default" solrconfig of 50 lines!

> 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.
