AWS Step Functions Supports Variables and JSONata
Step Functions - Yes, that orchestrator or workflow service in AWS used to be used primarily to call lambda functions in various formats or orders, but in recent years, it has become more and more popular due to its support for nearly all of the key AWS SDK integrations.
🌟 In fact, some things, no no many things can be done only by using step functions without even having a lambda functions or needing to write python or node.js code.
😫 But while writing step functions as an developer, Obviously you and me, for sure come across this situation of writing extra, extra steps to do simple manipulation of data in input or result and pass through to other steps.
😀 Now you don't need to do that, anymore. Your step functions can get smaller, lighter and shorter with less pass through manipulation states.
😅 Without further hyping, let's see what is that feature released by AWS.
📢 Variables :-
✓ With this option, you can declare your input variable at the top of step function and access in each and every step, right upto the bottom, without needing to pass through every step.
✓ Since now your variable is at the top, you can re-arrange or modify any of the intermediate without burden.
📢 JSONata :-
✓ It's a simple, lightweight query and transformation language for JSON data.
✓ Using this you can do things like, simple time/data format change to complex mathematical calculation right inside your step functions state itself, without needing to call an lambda functions to do this.
💬 Previously while you are writing step functions you would used JSONpath based expression intrinsic functions, so your step functions might looked bigger🙆. Now with JSONata you should see step functions much smaller 🤏 as the extra step of transition are neglected.
🏌️♂️If you are already working with step functions, then you are going to like this 🤩.
Hope you learned something new 🎉.
