music/mdbc - The most crucial recipe is a multi-site database cache (mdbc) that enable ONAP components that maintain state in a SQL database to avail the benefits of MUSIC without compromising their need to use transactional SQL DBs. These ONAP components can rely on existing db clustering techniques like MariaDB for transactionality and complex querying within a site. mdbc will intercept each of these read/write calls to the db cluster and mirror this state to other geo-distributed sites through MUSIC either synchronously or asynchronously (configurable at a table-level). For example, components like the ONAP Service Orchestrator that use MariaDB to maintain state can directly use this recipe with no change to their SQL code.

2018-12-13	Docker compose scripts for two mdbc sites	Rob Daugherty	12	-2/+397
	This is a two site installation, with a single cassandra container, two mariadb containers, and two mdbc-server containers. Server 1 exposes port 30001 and server 2 exposes port 30002. To build the docker images, first build mdbc software normally, then use the 'docker' maven profile: mvn -P docker clean install To bring up the environment: cd mdbc-packages/mdbc-docker/compose/two-sites docker-compose up Change-Id: I10155ebf47dec4e787d44b23886ab8453ac4315f Issue-ID: MUSIC-263 Signed-off-by: Rob Daugherty <rd472p@att.com>
