Seamlessly Execute Python ML Workloads in Java or Go Pipelines using Dataflow’s Multi-Language Capabilities

As Seen On

The advent of powerful programming languages such as Python, Java, and Go has enabled data engineers to explore and implement sophisticated Machine Learning (ML) workloads spanning various industries. One intriguing opportunity lies in running Python ML workloads from Java or Go pipelines. Utilizing Dataflow’s multi-language capabilities, data engineers can execute Python ML workloads seamlessly, opening up new possibilities for pipeline enrichment, availability of unique sources or transforms, or catering to subjective preferences.

Dataflow, a powerful, fully managed service for transforming and enriching data in real-time, has revolutionized the execution of ML workloads. Its multi-language capabilities are a game-changer, allowing users to run Python, Java, and Go workloads in an intertwined manner. Python’s preeminence in Machine Learning, combined with the wide usage of Java and Go in data processing, creates an ideal scenario for such multi-language operations.

One of the many ways to exploit Dataflow’s capabilities is through multi-language inference. There are two primary methods to accomplish it: using Java or Go RunInference transforms and creating a custom Python transform for pre/post-processing and inference.

Java or Go’s RunInference transforms allow users to run inference with the model while keeping most pre/post-processing in the primary language. This can be a desirable method for those who want to retain most of their pipeline code in Java or Go, only roping in Python for specific ML tasks. An example pipeline using the Java RunInference transform can be found on GitHub, providing a practical instance of this approach in implementation.

Alternatively, users can lean more heavily on Python by creating a custom Python transform for pre/post-processing and inference. This method uses an External Transform, linked with Python libraries, to handle the more detailed aspects of ML tasks. Those fully immersed in the Python ecosystem will find this method appealing.

It’s worth noting, however, that any approach you choose, Dataflow’s multi-language capabilities support a range of ML models. TensorFlow, PyTorch, Sklearn, XGBoost, ONNX, and TensorRT models are well-supported out-of-the-box with Beam 2.47. This flexible support makes it easier for data scientists and engineers to carry their preferred ML frameworks into the pipelines.

Even if your preferred framework is not directly supported, Dataflow offers the possibility of building your own custom model handler. This provides an endless scope for widening the real-world applicability of your ML workflows.

In conclusion, Dataflow’s multi-language capabilities signify a breakthrough in the execution of Python ML workloads in Java or Go pipelines. The range of support, flexibility in pipeline construction, and the ability to integrate best-in-class ML libraries make it a powerful tool for data engineers. The fusion of these capabilities gives data engineers the leeway to design and implement pipelines tailoring to their industry-specific needs, making the entire process of running ML workloads more streamlined, user-friendly, and efficient.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
