Versatile Data Kit is a data engineering framework that enables Data Engineers to develop, troubleshoot, deploy, run, and manage data processing workloads (referred to as "Data Jobs"). A "Data Job" enables Data Engineers to implement automated pull ingestion (E in ELT) and batch data transformation (T in ELT) into a database. Versatile Data Kit provides an abstraction layer that helps solve common data engineering problems. It can be called by the workflow engine with the goal of making data engineers more efficient (for example, it ensures data applications are packaged, versioned and deployed correctly, while dealing with credentials, retries, reconnects, etc.). Everything exposed by Versatile Data Kit provides built-in monitoring, troubleshooting, and smart notification capabilities. For example, tracking both code and data modifications and the relations between them enables engineers to troubleshoot more quickly and provides an easy revert to a stable version.
