Description

Currently calcite calcite.util.Source interface can be built only from File or URL. This forces data to be stored on disk or accessed remotely using URL api.

This proposal adds another Source implementation on the top of CharSource so calcite adapters can operate on in-memory elements like String or generic text sources.
