Validation service is a core A&AI microservice which implements a rule processing engine.
POMBA configures and deploys its own instance of validation service that consumes and publishes to POMBA topics in DMaaP.
Audit rules are stored in groovy format file. The file is files are injected into a service and rules are processed by the engine.
Currently audit rules are hand crafted, but eventually will be sourced from well formed ASDC models and from Data Dictionary. Existing rules are listed here.
POMBA will eventually support the mechanism of separting separating rules from validation service code, thereby allowing changing the rules rule updates without a rebuild or restart of the validation service.
