[jboss-jira] [JBoss JIRA] (WFLY-12222) Clustering subsystems integration with WildFly Discovery SPI (tracker Jira)

Clustering subsystems integration with WildFly Discovery SPI (tracker Jira) --------------------------------------------------------------------------- Key: WFLY-12222 URL: https://issues.jboss.org/browse/WFLY-12222 Project: WildFly Issue Type: Task Components: Clustering, mod_cluster Affects Versions: 17.0.0.Final Reporter: Radoslav Husar Assignee: Radoslav Husar Priority: Major Ultimately, we could employ WildFly Discovery SPI to handle services discovery in a generic way. However, since the subsystem currently only supplies one provider based on static discovery, its usefulness is limited. To untangle the chicken-egg problem, we could first integrate the clustering subsystems with the discovery SPI, # JGroups discovery # remote-cache-container remote servers # mod_cluster then supply discovery providers, # static list (implemented) # multicast-based # k8s-based (replacing JGroups' OPENSHIFT_PING, DNS_PING, KUBE_PING, etc) # cloud providers specific (replacing S3_PING, NATIVE_S3_PING, AZURE_PING, GOOGLE_PING, etc) This requires fixes to the discovery subsystem such as # ability to register new providers # changing static providers should require server reload # etc
