AWS Step Functions announces support for two new capabilities: Variables and JSONata data transformations. Variables allow developers to assign data in one state and reference it in a subsequent state, simplifying state payload management, reducing the need to pass data through multiple intermediate states. With support for JSONata, an open source query and transformation language, customers can now perform advanced data manipulation and transformation such as date and time formatting, and mathematical operations. Additionally, when using JSONata, we have simplified input and output processing by reducing the number of JSON transformation fields required to call services and pass data to the next state.
AWS Step Functions is a visual workflow service capable of orchestrating over 14,000 API actions from over 220 AWS services to build distributed applications and data processing workloads. With support for Variables and JSONata, developers can build distributed serverless applications faster and more efficiently with enhanced payload management capabilities. These features also reduce the need for custom code, lowering costs and reducing the number of state transitions needed to construct and pass data between states.
Variables and JSONata are available at no additional cost in: US East (N. Virginia, Ohio), US West (Oregon), Canada (Central), Europe (Ireland and Frankfurt), and Asia Pacific (Tokyo, Seoul, Singapore, and Sydney) with the remaining regions to follow in the coming days. We have also partnered with LocalStack and Datadog to ensure that their local emulation and observability experiences are updated to support Variables and JSONata. To learn more, please visit:
