Integration between Micronaut and Oracle Coherence

Micronaut Coherence

This project provides integrations between Micronaut and Oracle Coherence.

Documentation

See the Documentation for more information.

See the Snapshot Documentation for the current development docs.

Snapshots and Releases

Snapshots are automatically published to Sonatype OSS using GitHub Actions.

See the documentation in the Micronaut Docs for how to configure your build to use snapshots.

Releases are published to Maven Central via GitHub Actions.

Releases are completely automated. To perform a release use the following steps:

• Publish the draft release. There should be already a draft release created, edit and publish it. The Git Tag should start with v. For example v1.0.0.
• Monitor the Workflow to check it passed successfully.
• Celebrate!

micronaut-coherence's Issues

Make the Coherence instance type configurable

Feature description

Currently the Coherence instance type is always specified as Cluster Member. We should configure the Coherence instance as Client automatically (sensible default), if all configured sessions are either of type Coherence*Extend or gRPC. Users should also be able to explicitly configure (override) the setting through a Micronaut property.

See:

micronaut-coherence/coherence/src/main/java/io/micronaut/coherence/CoherenceFactory.java

Line 117 in 293b84a

coherence = Coherence.clusterMember(cfg);

As reference see: coherence-community/coherence-spring#71

Provide example apps

Would be great to have some example apps like we have here https://github.com/micronaut-projects/micronaut-oracle-cloud/tree/master/docs-examples where plp could just peek into working example. Also based on that we can extend launcher.

NPE: Cannot invoke "io.grpc.netty.NettyWritableBuffer.bytebuf()" because "frame" is null

Expected Behavior

No NPE raised by runtime.

Actual Behaviour

Attempting upgrade of micronaut-coherence to 3.4.0 and running GrpcProxyTest yields:

Version

3.7.3

If using the default Coherence Session, don't require users to reference the repository name in configuration

Feature description

Currently, we require each repository that will be used to be declared in configuration. However, if the user is just using the default Coherence Session, there is no benefit with continuing to require the repository reference.

This ultimately means that configuration for a repository is only necessary when using a Session other than the default.

Integrate Coherence CE 21.06.2

Feature description

Integrate Coherence CE 21.06.2 once available.
