@nzthiago This should work for any functions that have an azure event hub sdk. You should be able to find the correct sdk for your language here https://docs.microsoft.com/en-us/azure/event-hubs/sdks
Sure if you want to forego Functions bindings altogether you can just use the SDK for any of the languages in your own functions code, that is the workaround our customers are using. But if using bindings, .NET is the only one that lets you bind to EventHubClient.

After testing in production it turned out different tiers have different max message sizes.
standard: 1MB
basic: 256KB
We need to stick with 256KB for now. Also there is no way to get pricing tier for an Event Hub using SDK.

@alrod erally? Where did you see this? I can't find any different limits apart from the 1MB.
Would it maybe at least be possible to make the 256KB the default in the binding but allow in overwrite via the host.json config?!

I tested this using console app and latest eventhub sdk (4.1.0) sending messages of different sizes.
Overwriting in host.json sounds as good idea, I created an issue to track. As workaround you can bind to [EventHub(TestHubName)] EventHubClient client in azure function and send a message more than 256KB using EventHubClient.

Yeah I just tested myself and you are right, Basic event hub has still the limit of 256KB message size. Doesn't seem to be documented anywhere. I'll reach out to the PG.

@alrod - that workaround would only work for .NET Functions right? For other functions we'd have to wait until the linked issue you created is fixed?
