Hi, thanks for your article.

I think it is worth mentioning that static variable approach may not work for everything since:https://docs.microsoft.com/pl-pl/azure/azure-functions/functions-scale:

“A single instance may process more than one message or request at a time though, so there isn’t a set limit on number of concurrent executions.”

Basically, as long as it is thread-safe it works. If the client is not thread-safe, then you might find yourself in trouble :-)
