A quick note on this: the side-input API is still ongoing work and it turns out it’s more complicated (obviously … 😳) and we will need quite a bit more work on other parts of Flink before we can provide a good built-in solution.
In the meantime, you can check out the Async I/O operator [1]. I think this fits your use case of accessing an external system quite well because it allows firing off several request to external systems at the same time.
