> Key: CALCITE-3117
> URL: https://issues.apache.org/jira/browse/CALCITE-3117
> Project: Calcite
> Issue Type: Task
> Reporter: Stamatis Zampetakis
> Assignee: Stamatis Zampetakis
> Priority: Minor
>
> The goal of this issue is to identify and mark Calcite's public APIs. This
> can have bring various benefits to the project:
> * provide more flexibility to developers;
> * speed-up reviews;
> * enhance backward compatibility;
> * facilitate the life of end-users who will be exposed to fewer classes and
> interfaces.
> Let's list here packages, interfaces, and classes that should be part of the
> public API. As a first step let's focus exclusively on completing the list
> and not argue about others proposals. It will be easier to solve
> disagreements afterwards as soon as we have a rather complete list.
