File Writer

The File Writer connector performs a straightforward task of writing the data received from the South connector to a designated folder.

Specific settings​

  • Output folder: This is the directory where files will be stored. In the case of a relative path, it is computed based on the Data folder mentioned in the About section.
  • Prefix filename: You can include a prefix to be added to the filename.
  • Suffix filename: You have the option to append a suffix to the filename, which appears just before the file extension.
tip

Prefix and suffix options can incorporate the internal variables @ConnectorName and @CurrentDate. For instance, when using @ConnectorName- as a prefix and -@CurrentDate as a suffix, a filename like example.file will result in an output format of <ConnectorName>-example-<CurrentDate>.file, where <CurrentDate> will be replaced with the current date and time in the yyyy_MM_dd_HH_mm_ss_SSS format.

JSON payloads​

In the case of JSON payloads, the JSON data is stored in a JSON file. For instance:

JSON file
[{"timestamp":"2020-01-01T00:00:00.000Z","data":"{ value: 28 }","pointId":"MyPointId1"}]
