​

​
Parquet file requirements

Every Parquet file must include a timestamp column, and must follow exactly one of the two supported schemas: Flat Dataset or Channel Per Row (not both). Example: Flattened Parquet Channel names A Parquet column location containing {lat, lon} imports as:
  • location.lat
  • location.lon

​
Parquet: Flat Dataset settings

​
Parquet: Channel Per Row settings

Example: Channel Per Row Parquet layout Settings used for this layout:

​
TDMS settings

Settings in the Upload TDMS dialog. TDMS imports use the group and Channel hierarchy embedded in the file to derive Channel names. The TDMS dialog does not expose a per-Channel configuration table.
