-------------------------------------------
Summary: Add a group processor
Key: KARAF-6864
URL: https://issues.apache.org/jira/browse/KARAF-6864
Project: Karaf
Issue Type: New Feature
Components: decanter
Reporter: Jean-Baptiste Onofré
Assignee: Jean-Baptiste Onofré
Fix For: decanter-2.6.0
The user can define a set of properties and we group all events with same
properties value, and send at timeout.
For instance, we can group like:
{code:java}
{'field1': "a", "field2": 'b', "field3": "c"} -> group by: a, b -> Map<Pair<a,
b>, List {'field1': "a", "field2": 'b', "field3": "c"} >
if b = null -> Map<Pair<a, null>, List {'field1': "a", "field2": null,
"field3": "c"} >
if a = null -> Map<Pair<null, b>, List {'field1': null, "field2": "b",
"field3": "c"} >
if a = null, b = null -> Map<Pair<null, null>, List {'field1': null, "field2":
null, "field3": "c"} > {code}
