Historically I’ve written several services that load up some big datastructure (10s or 100s of GB), then expose an HTTP API on top of it. Every time I’ve done a quick implementation in Python of a service that then became popular (within a firm, so 100s or 1000s of clients) I’ve often ended up having to rewrite in Java so I can throw more threads at servicing the requests (often CPU heavy). I may have missed something but I couldn’t figure out how to get the multi-threaded performance out of Python but of course no-GIL looks interesting for this!
