Functionality
This section includes the functionalities offered by Prophecy Libs.
Pipeline Monitoring
Out of the box, Spark lacks auditing or monitoring capabilities for its Pipelines. Prophecy Libs bridges this gap by offering step-by-step transformation monitoring, enabling users to easily comprehend Pipeline execution metrics (e.g., times of arrival, amount of data processed), data profiles, and detailed debugging information at every Pipeline step.
Pipeline Monitoring is fully independent of the Prophecy IDE, using standard metadata tables. Reading and leveraging this information for downstream consumption is as simple as reading a table.

Utility Functions
The standard Spark function library covers the basics of data transformation but often falls short for enterprise data platforms. Prophecy Libs offers additional utility functions essential for complex data operations, especially during legacy platform migrations.
This includes comprehensive data lookup functionality, configuration management, complex type processing UDFs, secret manager integration, and other high-demand functions.
Legacy Connectors
Prophecy-libs provides several high-performance connectors missing from the standard Spark source palette. This includes an EBCDIC fixed format, SFTP, and REST API connectors, ensuring seamless integration with legacy systems.
