It would be great to emit errors from this plugin, since it's very common for a part of records to fail to insert (but not all of them). But unfortunately SinkEmitter does not support emitting errors (codelink), also even if it did it would not help. We don't know if it's an error on transform stage. We only know that once the batches are submitted and results are checked. This happens on task finalization at (RecordWritter#close)
