Standalone
When large scale and high concurrency checks are not required, DQ can be installed and operated entirely on a single host. In this mode, DQ will leverage a Spark Standalone pseudo cluster where the master and workers run and use resources from the same server. DQ also requires a Postgres database for storage and Java 8 for running the DQ web application. It is possible to install each of the Spark, Postgres, and Java 8 components separately and install DQ on top of existing components. However, we offer a full installation package that installs these components in off-line mode and install DQ in one server.
