I have a lambda function, F1, in Nodejs whose main purpose is to read the contents of a file that is deposited in S3 through another process.
Let's say there are 10 products in this archive. I need to loop through these products to call the F2 function 10 times.
How do I implement this process with StepFunctions ?
According to the documentation you can create a Lambda Function that works as an "Iterator":
Ex:
exports.iterator = function iterator (event, context, callback) {
let index = event.iterator.index
let step = event.iterator.step
let count = event.iterator.count
index += step
callback(null, {
index,
step,
count,
continue: index < count
});
}
