The GWC S3 blobstore has been used for cloud deploys in a while, it's time to make it officially supported.

As more deploys target the cloud, it becomes important to have supporting modules available as officially supported extensions. GWC S3 blobstore has been used in a number of production sites so far, so it's an obvious choice for supported status.

The GeoServer module only contains a web UI to configure the blobstore, the actual machinery is in GWC already and part of the released WAR file.

Also, the module already has documentation.

Actions needed for graduation:

• Moving the module from community to extension in the build system.
• Cleaning up eventual QA failures
• Updating the website template to make the extension available.
• Updating the pom.xml contact information.
• Updating documentation location, remove warnings related to community status.

The developers guide lists several requirements for community modules graduating to an extension:

1. The module has at least a “handful” of users

   • GeoSolutions has observed a number of sites running the module, at least 3 recently.

2. The module has a designated and active maintainer

   • Andrea Aime (GeoSolutions) is willing to act in this capacity.

3. The module is considered “stable” by the majority of the PSC

   • The module has been unchanged and working for several releases.

4. The module maintains 40% test coverage

   • Module has 84% test coverage as reported by IntelliJ "run with coverage"

5. The module has no IP violations

   • Module was largely written by Niels in 2015, he signed the CLA

6. The module has a page in the user manual

   • It does indeed

7. The maintainer has signed the GeoServer Contributor Agreement

   • OSGeo CLA signed
