-When you enable partitioned copy, Data Factory runs parallel queries against your Teradata source to load data by partitions. The parallel degree is controlled by the [`parallelCopies`](copy-activity-performance.md#parallel-copy) setting on the copy activity. For example, if you set `parallelCopies` to four, Data Factory concurrently generates and runs four queries based on your specified partition option and settings, and each query retrieves a portion of data from your Teradata database.

-You are suggested to enable parallel copy with data partitioning especially when you load large amount of data from your Teradata database. The following are suggested configurations for different scenarios. When copying data into file-based data store, it's recommanded to write to a folder as multiple files (only specify folder name), in which case the performance is better than writing to a single file.
