Trifacta Photon is an in-memory running environment that is hosted on the Trifacta node. This environment is initialized only when a job is queued for execution on it. Designed for small- to medium-sized jobs, it offers superior performance due to its location on the Trifacta node and its in-memory processing.
When you choose to run a job in the Designer Cloud application , Trifacta Photon is selected as the default running environment if it is available and the job size is estimated to small or medium.
Tip: Trifacta Photon is also used for sampling jobs that are configured to use the Quick Scan method. For more information, see Overview of Sampling.
Tip: In the Run Job page, select Photon to run the job on this running environment.
Trifacta Photon is enabled by default but can be disabled as needed.
NOTE: Trifacta Photon cannot process numeric values with more than 16 digits. Columns containing such values are converted to String values, and the digits beyond 16 are converted to 0.
NOTE: When a recipe containing a user-defined function is applied to text data, any null characters cause records to be truncated during Trifacta Photon job execution. In these cases, please execute the job on Spark.
NOTE: For more information on configuring Trifacta Photon, see Configure Photon Running Environment.
