Class JobScheduler.Groups

java.lang.Object

org.neo4j.scheduler.JobScheduler.Groups

Enclosing interface:

JobScheduler

public static class JobScheduler.Groups
extends Object

This is an exhaustive list of job types that run in the database. It should be expanded as needed for new groups of jobs. For now, this does minimal configuration, but opens up for things like common failure handling, shared threads and affinity strategies.
