Mobile Delivery Service (MDS) is a core component of the mPaaS platform. It manages and publishes version upgrade packages, hotpatching packages, and HTML5 offline packages. The service also supports managing configurations, whitelists, and publishing rules.
After you integrate MDS into a client, you can generate new packages in the mPaaS plugin and publish them from the MDS console. The client then receives the package and performs the upgrade. The service also supports canary releases that use whitelists. You can use advanced filtering rules, such as specifying device models, for more precise releases.
Features
Canary release
Before a formal release, you can use whitelists to conduct small-scale releases to groups such as internal employees. This helps verify that the new package works as expected. You can also perform time-window canary releases, which publish the package to a specific number of users within a set time frame. If the package performs as expected, you can then push the release to all users.
Advanced filtering
During a canary release, you can use advanced rules to define more precise whitelist groups, such as releasing only to users of Xiaomi phones. Multiple filtering rules can be combined. The package is pushed only if all rule conditions are met.
Real-time rollback
This feature is only supported for hotpatching. Issues can occur during an official launch, even after a successful canary release. If an issue occurs, you can perform a real-time rollback, which automatically reverts the client to the pre-release version.
Custom signature verification
To ensure security, hotpatching includes a custom signature verification process. This process guarantees the authenticity of the script source. The mPaaS plugin lets you generate and sign hotpatching resource packages.
