Overview
...
MUSIC was released in the ONAP Beijing release and provides a service with recipes that individual ONAP components and micro-service can use for state replication, consistency management and state ownership across geo-distributed sites. This is a crucial component enabling ONAP components to achieve geo-redundancy (platform-maturity resiliency level 3).
In this release we plan to provide to address the following items:
...
| Deliverable Name | Deliverable Description |
|---|---|
| Source code and REST API | The entire source code for the MUSIC service and the PROM recipe and the corresponding REST API to access it. |
| Compilation scripts | Script to generate the MUSIC war and jar file that can be deployed in the Apache Tomcat webserver |
| Installation guide | Document that describes how MUSIC can be installed in containers |
| Tool description | Complete description of the inner workings of MUSIC and how it performs state management |
| Basic Benchmarks | Basic performance benchmarks for the MUSIC operations |
| API documentation | REST API documentation in Swagger |
| Test Cases | Junit test cases covering sufficient parts of MUSIC code |
| Design Document for MUSIC Federation | Provide the design to make MUSIC a fully sharded, scale out system, where as many ONAP sites/component replicas can be added as required for performance. |
| Design Document for RDBMS Support | Provide the design 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. |
