The vgtid structure facilitates both: determining the stream sources and maintaining state. vgtid is a list of tuples:

the minikube-instructions. This was done to gain better understanding of the general deployment structure and the integration with the core components. • The initially enumerated application endpoints and mostly well-documented, making it particularly easy for the auditors to review the software’s structure. Except for the SQL parser, none of the components had overly complex logic or included typically
