This section covers key known limitations of Trifacta®

NOTE: This list of limitations should not be considered complete.

General Limitations


  • All values displayed or generated in the application are based on the currently displayed sample. 
    • Transforms that generate new data may not factor values that are not present in the current sample.
    • When the job is executed, transforms are applied across all rows and values in the source data.
    • Transforms that make changes based on data values, such as header and valuestocols, will still be configured according to sample data at the time of that the step was added, instead at execution time. For example, all of the values detected in the sample are used to determine the columns of a valuestocols transform step based on the selected sample when the step was added.
  • Random samples are derived from up to the first 1 GB of the source file. 
    • Data from later parts of a multi-part file may not be included in the sample.


  • The product supports a variety of global file encoding types for import. 

  • Within the application, UTF-8 encodings are displayed. 
    • Limited set of characters allowed in column names.
    • Header does not support all UTF-8 characters.
    • Emoji are not supported in data wrangling operations.
    • Umlauts and other international characters are not supported when filtering datasets in browsers of external datastores.
  • States and Zip Code Column Types and the corresponding maps in visual profiling apply only to the United States.
