Andrei Sereda updated CALCITE-3560:
-----------------------------------
Description:
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] or
[File|https://docs.oracle.com/javase/8/docs/api/java/io/File.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]
(rather their factory equivalent like
[CharSource|https://guava.dev/releases/19.0/api/docs/com/google/common/io/CharSource.html])
so adapters can operate on in-memory elements like String.
