    Description

      A single task may be writing multiple files at the same time. If the parallelism is too high, it may lead to a large number of small files. If the parallelism is too small, the performance is not enough. This requires that the user can specify parallelism.

      • Default is the same as upstream transformation
      • Users can specify parallelism too.
