I am pleased to announce the first alpha release of Magma 42.
42 adds the ability to start the repository which was output from MagmaRepositoryController>>#fullBackupTo:, at which point it will automatically "join" the MagmaNode of which the original repository is a part, and becoming a read-only "warm backup" that is updated continuously by the original server running at the #primaryLocation.
A MagmaNode is simply an Array of MagmaRemoteLocations that act as a cluster of servers each supporting their own physical copy of one logical repository. Besides the improved read-scale, we get continuous, automatic backups, 24x7x365 operation, and the ability for the Node to crawl from one data-center to another without ever bringing the system down.
This alpha release passes the entire legacy test-suite and has been manually unit-tested for a variety of the MagmaNode test cases. Some day I will adjust the automated test suite to include these tests.
Enjoy, Chris
