[jira] [Created] (SPARK-34324) FileTable should not list TRUNCATE in capabilities by default

L. C. Hsieh created SPARK-34324:
-----------------------------------

             Summary: FileTable should not list TRUNCATE in capabilities by default
                 Key: SPARK-34324
                 URL: https://issues.apache.org/jira/browse/SPARK-34324
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: L. C. Hsieh
            Assignee: L. C. Hsieh


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.
