The eventhubs Python client provides,

• a sender to publish events to the Event Hubs service.
• a receiver to read events from the Event Hubs service. On Python 3.5 and above, it also includes,
• async sender and receiver that supports async/await methods.
• an event processor host module that manages the distribution of partition readers.

Build and Install

Local

The core library requires Apache Proton-C and its Python binding.

• build Proton-C: https://github.com/apache/qpid-proton/blob/master/INSTALL.md

For eventprocessorhost, you will also need (list for Fedora 26, adjust for other distributions),

• libs: libxml2-devel, libxslt-devel, libffi-devel, python3-cffi, redhat-rpm-config
• Python packages: requests, bs4, lxml, azure-storage, azure-storage-blob

On Windows a private patch to proton-c code is required for the library to work.

Docker

The following Dockerfile at ./examples/Dockerfile creates a Docker image with Apache Proton and the Azure Event Hubs SDK.

The base image is Python 3.6-slim-stretch and Proton 0.18.1 but you can set the PYTHON_IMAGE_VERSION PROTON_VERSION PYTHON_DIR_VERSION when building the image.

docker build -t azure-eventhubs-sdk --build-arg PYTHON_IMAGE_VERSION=3.6-slim-stretch --build-arg PROTON_VERSION=0.18.1 --build-arg PYTHON_DIR_VERSION=3.6 .

After the image is built you can run the samples with

docker run -it azure-eventhubs-sdk python examples/send.py

Note that you have fill the Event Hub connection parameters in the example py files.

Examples

• ./examples/send.py - use sender to publish events

• ./examples/recv.py - use receiver to read events

• ./examples/send_async.py - async/await support of a sender

• ./examples/recv_async.py - async/await support of a receiver

• ./examples/eph.py - event processor host

• ./examples/Dockerfile - create a Docker image with Apache Proton and Azure Event Hubs SDK

• ./tests/send.py - how to perform parallel send operations to achieve high throughput

• ./tests/recv.py - how to write an event pump to read events from multiple partitions

Logging

• enable 'eventhubs' logger to collect traces from the library
• enable AMQP frame level trace by setting environment variable (export PN_TRACE_FRM=1)
