New features in Dublin
- Provide MUSIC as a fully sharded, scale out common service, where as many ONAP sites/component replicas can be added as required for performance. The significant technical challenge is to eliminate the need for Zookeeper and build MUSIC completely based on Cassandra while preserving all its guarantees. We expect this change to improve both deployabiity deployability (just one tool – Cassandra) and performance (initial benchmarks indicate a factor of at least 4-5 times in terms of throughput). This is a crucial precursor for its use in edge computing and as the state management service for a federated ONAP.
- Provide the seed code to allow MUSIC to support database (RDBMS) clustering across sites using the mdbc recipe wherein ONAP components that require it can continue using a SQL database within a site while using MUSIC is as the underlying transport layer across sites, with much better performance than standard solutions like Gallera clustering.
