Draft of improvements and breaking changes

New features

• Job Analysis Performance mode: when a job is analyzed for the first time, JobRunr checks whether it can be cached. If so, all subsequent calls will be a lot faster. If job is not cacheable this is displayed in the dashboard.
• Updated Spring boot starter with
  • Support for @Recurring annotation for Recurring jobs
  • Support for disabled Recurring jobs using "-"
  • Support for multiple datasources in Spring (a specific datasource for JobRunr)
  • Support for Spring Actuator Health Endpoint
  • Support for Spring Actuator Metrics Endpoint
• New Micronaut feature with
  • Support for @Recurring annotation for Recurring jobs
  • Support for disabled Recurring jobs using "-"
  • Support for multiple datasources in Micronaut (a specific datasource for JobRunr)
  • Support for Micronaut Health Endpoint
  • Support for Micronaut Metrics Endpoint
• New Quarkus extension with
  • Support for @Recurring annotation for Recurring jobs
  • Support for disabled Recurring jobs using "-"
  • Support for multiple datasources in Quarkus (a specific datasource for JobRunr)
  • Support for Quarkus Health Endpoint
  • Support for Quarkus Metrics Endpoint
• CPU Allocation Irregularities detection: as JobRunr uses NTP and timeouts to detect if a BackgroundJobServer is still alive, it is important that the JVM does not stop too long. JVM's can stop due to full garbage collection taking too long or if they are running on shared cloud hardware where resources are stealed by other processes. JobRunr now detects this and shows a warning in the dashboard as it can impact the cluster.
• JobRequest and JobRequestHandler: this release introduces the JobRequestScheduler a new way to create jobs using objects instead of lambda's.
• Static method support: JobRunr can now create jobs using lambda's referencing static method

Breaking changes:

• the pollIntervalInSeconds can not be smaller than 5 or else an exception will be thrown
• StateChanges are now validated. This will impact people who are using ElectStateFilters and are changing states that are not valid (e.g. from Failed to Succeeded, from Processing to Processing).
• JobRunr.configure()....initialize() now returns a JobRunrConfigurationResult which contains the JobScheduler and the JobRequestScheduler
• BackgroundJobServerConfiguration andWorkerCountPolicy(BackgroundJobServerWorkerPolicy backgroundJobServerWorkerPolicy) has been renamed to BackgroundJobServerConfiguration andBackgroundJobServerWorkerPolicy(BackgroundJobServerWorkerPolicy backgroundJobServerWorkerPolicy)
