DSUS

Data Support Update Service

Overview

The principal responsibility of the Data Support Update Service (DSUS) is the processing of Deployment Queue entries created by RCKMS Administrators or Jurisdictions via CAT and MTS.

In addition, DSUS is responsible for synchronizing the authored-rule data state between environments through communication with Cloud Storage Buckets, and the Document Database.
