Represents the end-user, a persona who is issuing queries to the Druid Query APIs

ADMIN

public static final DruidException.Persona ADMIN

Represents an administrative user, a persona who is interacting with admin APIs and understands Druid query concepts without necessarily owning the infrastructure and operations of the cluster

DEVELOPER

public static final DruidException.Persona DEVELOPER

Represents someone who has all of the context and knowledge to be actively diving into the Druid codebase. This persona exists as a catch-all for anything that is so deep and technically in the weeds that it is not possible to make a message that will make sense to a different persona. Generally speaking, there is a hope that only DEFENSIVE error messages will target this persona.
