Today’s data applications blur the distinction between data scientists and data engineers. Leading data teams handle complex code logic: machine learning, time series processing, and graph algorithms. All this when working with real-time data sources and changing data.
Traditional data processing frameworks were not designed for the challenges we face today. They force developers to compromise on performance, scalability, or ease of use.
Pathway is a Python-first framework that lets developers and ML engineers easily implement production-grade applications involving Machine Learning, LLM's, or advanced algorithms.
To provide a smooth and scalable experience with live data sources, Pathway takes care of data updates, consistency, and versioning. Developers can focus on the logic and not the plumbing.
Pathway is based on the fastest Rust runtime on the market. Its engine performs incremental computing as input data changes, leveraging the best features of Timely and Differential Dataflow, along with proprietary research.
Use it for time series analysis, alerting and anomaly detection, graph analysis, LLM applications, real-time ML, and any other data pipelines you like.Check out our developer hub
Pathway provides a dramatic ease of prototyping with interactive code logic. You can easily work in notebooks, prototype your data processing pipeline, and connect or simulate live data sources.
All this with a standard Python environment. Forget the pains of setting up a local cluster just to test your application with a tuned model setting. Pathway is a pip-installable Python library.
Use the same production code and runtime engine for data science experiments, scaled production deployment in containers, and CI/CD unit tests.
Pathway provides convenient library routines for processing event streams at scale and cross-referencing data from different sources.
Create live incremental data connections to databases, API’s, files, S3, logstash, Kafka, as data sources or sinks - or add your own custom connectors in Python.
Pathway ensures that all live data source updates are taken care of, so you don’t have to worry about source synchronization.
Your code can call external functions, API’s, and models such as LLM’s - do an “apply” or “async_apply”, the choice is yours.
From decision trees to nearest neighbors search, Pathway enables you to perform real-time learning and inference, with forgetting.
Pathway provides ways to quickly retrieve the most relevant data to your AI application’s search context - from vector indexes to knowledge graph retrieval.
Use Pathway as an in-memory service to answer queries, retrieve up-to-date features with sub-millisecond latency.
Automatically notify users and down-stream systems when answers to registered queries have changed based on fresh data.
Apps built with Pathway ran faster than those in traditional frameworks, in both streaming and batch.See benchmarks
Your Pathway code is production-grade already as you create it in your IDE or notebook. You don’t have to worry about scalability issues when you put it in production.
And, as a Python developer, you will never again have to worry about gluttonous JVM’s running out of resources. Promise.
