--------------------------
Summary: service orchestration
Key: SC-21
URL: https://issues.apache.org/jira/browse/SC-21
Project: Apache ServiceComb
Issue Type: New Feature
Components: Java-Chassis
Reporter: Eric Lee
orchestration of service invocation and aggregation of data from multiple
services based on configured rule
eg. a user request requires calling service a/b/c/d in order: request -> a -> b
-> c -> d -> response
this creates a tight coupling among services a/b/c/d.
better solutions:
request -> aggregator -> response (aggregator calls a/b/c/d in sequence based
on configured rule)
request -> a -> message queue -> b -> queue -> c -> queue -> d
both ways no coupling among the services.
this epic is about solution 1
