Azure Event Hub Python SDK - exceptions

If I have 1 throughput unit (which allows 1000 msg/sec or 1Mb/sec) for an Event Hub and try to send more than 1000 msg/sec does the Azure Python SDK throw an exception or have some sort of return code that would notify me that I've exceeded my quota?

There are quotas and limits for Event Hubs(Service Bus).

The number of concurrent connections on a namespace for Event Hubs is 1,000 for NetMessing protocol or 5,000 for AMQP, see below:

For the message or event size, the entity name limits 50 charaters, and the maximum size of event is 256KB, see below:

About more details, you can refer to https://azure.microsoft.com/en-us/documentation/articles/service-bus-quotas/ to know it.

If you are developing IoT application and the throughput of data exceeds the quota of Event Hubs, I recommend to use the Azure IoT Hub. You can refer to https://azure.microsoft.com/en-us/documentation/articles/iot-hub-compare-event-hubs/ to know their differences.

Defect is that Azure IoT Hub has SDK for C, .Net, Java, NodeJS currently, but no SDK for Python. You can refer to https://azure.microsoft.com/en-us/documentation/articles/iot-hub-sdks-summary/ to know IoT SDK, or refer to https://azure.microsoft.com/en-us/documentation/articles/iot-hub-sdks-summary/ to use the IoT Hub REST APIs.
