HotRod-based distributed session manager
WFLY-7719 seeks to add a new distributed session manager implementation to WildFly that uses a HotRod client to store session data into a remote Infinispan cluster. This future provides a system an additional dimension with which to scale, by allowing the caching layer (i.e. session storage) to scale independently from the application servers themselves. The session manager implementation will conform to the SPI provided by the org.wildfly.clustering.web.spi module, allowing the same session manager implementation to support multiple servlet containers, including WildFly/Undertow and Tomcat (via https://github.com/wildfly-clustering/wildfly-clustering-tomcat).
Port hotrod-based session manager implementation from http://github.com/wildfly-clustering/wildfly-clustering-web-hotrod to WildFly
Add ability to configure new session manager to distributable-web subsystem
Add ability to configure individual web applications to use new session manager via deployment descriptor
Utilize HotRod administration interface to dynamically create remote caches per web application, instead of using single cache for all deployments
Extract logic common to both (i.e. embedded infinispan vs remote infinispan) session manager implementations into a common module
Clustering testsuite will add new variants for validating SESSION and ATTRIBUTE granularity session persistence to Infinispan-server
QE’s smartfrog testsuite should add new variations of their tests as well.
Community documentation of distributable-web subsystem to be updated to include configuration of hotrod-based session manager
