--------------------------------------

             Summary: Allow generic data source (eg. InputStream) in CSVAdapter or FileAdapter(s)
                 Key: CALCITE-3560
                 URL: https://issues.apache.org/jira/browse/CALCITE-3560
             Project: Calcite
          Issue Type: Improvement
          Components: csv-adapter, file-adapter
    Affects Versions: 1.21.0
            Reporter: Andrei Sereda
            Assignee: Andrei Sereda


Currently CSV Adapter requires data to be stored on disk or remotely because table constructor argument is [URL|https://docs.oracle.com/javase/8/docs/api/java/net/URL.html]. 

Change CSV and File adapter to accept more generic source like [Readable|https://docs.oracle.com/javase/8/docs/api/java/lang/Readable.html] or [InputStream|https://docs.oracle.com/javase/9/docs/api/java/io/InputStream.html] so adapters can operate on in-memory elements like String.
