Subject Re: (ANNOUNCEMENT) Solr Examples reading group
Date Fri, 07 Oct 2016 17:04:02 GMT
The current direction is JSON. So yeah, I don't think YAML discussion
will get very far.

The problem with examples is that they also serve as documentation and
as a master source for configuration snippets (e.g. language-specific
types). Changing that is happening in several different JIRAs, but it
is not a perfect process.

Regards,
   Alex.
