SOLR-5955 describes a feature to automatically create a ConfigSet, based on another one, from a collection API call (i.e. one step collection creation). Discussion there yielded
SOLR-7742, Immutable ConfigSet support. To close the loop, we need support for a ConfigSet management API.
The simplest ConfigSet API could have one operation:
create a new config set, based on an existing one, possible modifying the ConfigSet properties. Note you need to be able to modify the ConfigSet properties at creation time because otherwise Immutable could not be changed.
Another logical operation to support is ConfigSet deletion; that may be more complicated to implement than creation because you need to handle the case where a collection is already using the configuration.
