@paul-rogers I follow your explanation except for the last paragraph.
The Drill UI let's me update storage plugins and their formatters at
runtime (at least on my laptop) by going to **Storage** tab and clicking on
**Update** for a plugin. It also let's me add storage plugins provided the
necessary jars are in the classpath. I thought the goal of this change was to
address the fact that such a runtime update cannot be propagated to the cluster
atomically, so it is unreliable to reference a FormatPluginConfig by name
(which was done previously). It is, however, safe to copy the entire
FormatPluginConfig into the query plan as you said. Is this accurate?
