Installing Data Quality & Observability Classic on Spark Standalone Self-hosted

Data Quality & Observability Classic can be installed and operated on a single standalone host, which is useful when large scale and high concurrency checks are not required. In this mode, DQ leverages a Spark Standalone pseudo cluster in which the master and workers run and use resources from the same server.

The DQ Standalone application consists of the following components:

• DQ Web
• DQ Agent
• DQ Metastore (PostgreSQL database)
• Spark (pullup only)

Data Quality & Observability Classic provides the option to include the PostgreSQL metastore in the installation or use an external PostgreSQL metastore (recommended).
