>             Project: Calcite
>          Issue Type: Improvement
>          Components: csv-adapter, file-adapter
>    Affects Versions: 1.21.0

> Currently calcite Source interface can be built only from [File|https://docs.oracle.com/javase/8/docs/api/java/io/File.html] or [URL|https://docs.oracle.com/javase/8/docs/api/java/net/URL.html]. 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|https://guava.dev/releases/19.0/api/docs/com/google/common/io/CharSource.html] so calcite adapters can operate on in-memory elements like String or generic text sources.
