Sentry For Data: Error Monitoring with PySpark` is a new integration for PySpark, the Python API for Apache Spark, that provides error monitoring and observability tooling for data pipelines. The integration allows errors to be tracked, assigned, and grouped, with metadata and breadcrumbs that help isolate the source of the error. It works out of the box for SparkSQL, Spark Streaming, and Spark Core, and can be customized based on the needs of the setup. To get started, install the Sentry Python SDK on the Spark execution environment, initialize Sentry before creating the SparkContext, and instrument both driver and worker clusters. The integration provides full context events in Sentry that can help debug errors more efficiently.
