All Implemented Interfaces:

NodeServiceAuditor, UserServiceAuditor, net.solarnetwork.service.PingTest, net.solarnetwork.service.ServiceLifecycleObserver

public class JdbcUserServiceAuditor
extends JdbcNodeServiceAuditor
implements UserServiceAuditor

JDBC based implementation of UserServiceAuditor.

This service coalesces updates per user/service/hour in memory and flushes these to the database via a single "writer" thread after a small delay. This design is meant to support better throughput of audit updates, but has the potential to drop some count values if the service is restarted.

The fact that this implementation extends JdbcNodeServiceAuditor is a convenience only. All references to "nodes" in this implementation can be thought of as "users".
