# Additional Considerations for `TiDB Lightning`

__*zz-Issue-Parquet*__

+ Working with `TiFlash`
  + You can import data into a table with TiFlash replica(s)
  + TiFlash replica(s) might slow down the data importing procedure
  

-------------------------------------------------------------
Whether you've created a `TiFlash` replica of a table or not, you can use `TiDB Lightning` to import data into that table. However, in this scenario, `TiDB Lightning` takes longer to import data, depending on factors such as the network card bandwidth of the `TiDB Lightning` deployment machine, the `CPU` and disk load of the `TiFlash` node, and the number of `TiFlash` replicas.
