Yonik Seeley commented on SOLR-3251:
------------------------------------
bq. Does this imply that the schema would be writeable?
The in-memory schema object yes.
The question is how to persist changes. I was thinking it might be easiest to
keep a separate file alongside schema.xml for dynamically added fields for now.
The term "dynamicFields" has already been taken though and we probably
shouldn't overload it. Maybe extra_fields.json? Or maybe even
schema.json/schema.yaml that acts as an extension of schema.xml (and could
acquire additional features over time such as the ability to define types too?)
But a separate file that just lists fields will be much quicker (and easier) to
update. Reloading a full schema.xml (along with type instantiation) would
currently be somewhat prohibitive.
