[jira] [Created] (ARROW-6299) [C++] Simplify FileFormat classes to singletons

Benjamin Kietzman created ARROW-6299:

             Summary: [C++] Simplify FileFormat classes to singletons
                 Key: ARROW-6299
                 URL: https://issues.apache.org/jira/browse/ARROW-6299
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Benjamin Kietzman
            Assignee: Benjamin Kietzman


ParquetFileFormat has no state, so passing it around by shared_ptr<FileFormat> is not necessary; we could just keep a single static instance and pass raw pointers.

[~wesmckinn] is there a case where a FileFormat might have state?
