Sequences of operations that end-users execute in the Trifacta® application are rendered as commands in Wrangle (a domain-specific language for data transformation). When a job is executed, the Wrangle  recipe of steps is executed against the entire dataset. In the following diagram, you can review the layers that execute Wrangle  recipes across your dataset.

  • Wrangle  recipe: End-users create these sequential recipes by performing point-and-click operations on sampled data in the application. These recipes are stored in the Trifacta database and can be executed at any time against the full dataset.
  • Wrangle  compiler:
    • Dataflow Compiler: This component compiles your recipe into a set of commands that can be executed against the specified execution target.
    • Dataflow Optimizer: The optimizer reviews the set of compiled commands to perform general optimizations for the queries.
    • Target Optimization and Specialization: The Wrangle  compiler performs additional optimizations and addresses any special requirements depending on the execution target. 
  • Extensible Function Library: Optionally, developers can create user-defined functions using Java. 
  • Execution Environments: The Trifacta platform supports a variety of environments for execution of jobs.
