> abstract class {{FileTable}} now lists {{TRUNCATE}} in its {{capabilities}}, but {{FileTable}} does not know if an implementation really supports truncation or not. Specifically, we can check existing {{FileTable}} implementations including {{AvroTable}}, {{CSVTable}}, {{JsonTable}}, etc. No one implementation really implements {{SupportsTruncate}} in its writer builder.
