Summary: Simple async event processing for SCM
Key: HDDS-25
URL: https://issues.apache.org/jira/browse/HDDS-25
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: SCM
Reporter: Elek, Marton
Assignee: Elek, Marton
Fix For: 0.2.1
For implementing all the SCM status changes we need a simple async event
processing.
Our use-case is very similar to an actor based system: we would like to
communicate with full asny event/messages, process the different events on
different threads, ...
But a full Actor framework (such as Akka) would be overkill for this use case.
We don't need distributed actor systems, actor hierarchy or complex resiliency.
As a first approach we can use a very simple system where a common EventQueue
entry point could route events to the async event handlers
