Azure Event Hubs Connector for Apache Spark
This is the source code of the Azure Event Hubs Connector for Apache Spark.
Azure Event Hubs is a highly scalable publish-subscribe service that can ingest millions of events per second and stream them into multiple applications.
Spark Streaming and Structured Streaming are scalable and fault-tolerant stream processing engines that allow users to process huge amounts of data using
complex algorithms expressed with high-level functions like `map`, `reduce`, `join`, and `window`. This data can then be pushed to
filesystems, databases, or even back to Event Hubs.
By making Event Hubs and Spark easier to use together, we hope this connector makes building scalable, fault-tolerant applications easier for our users.
