In that release, it was intended to be an application that established a software architecture for building CDAP applications that demonstrate sufficient unit test coverage and reusable libraries for ingesting DMaaP MR feeds formatted according to the VES standard. Functionally, it performs a comparison of an incoming performance metric(s) against both a high and low threshold defined and generates CL events when threshold are exceeded. -In Amsterdam release, TCA was deployed into 7 node CDAP cluster. However since Beijin release as ONAP required application to be containerized and deployable into K8s, a wrapper TCA CDAP container was built using CDAP SDK base image on which TCA application is deployed. +In Amsterdam release, TCA was deployed into 7 node CDAP cluster.
