----------------------------------
Summary: Reduce REST API Request/Response redundancy
Key: FLINK-14147
URL: https://issues.apache.org/jira/browse/FLINK-14147
Project: Flink
Issue Type: Improvement
Components: Runtime / Web Frontend
Reporter: Yadong Xie
Attachments: 16_17_07__09_20_2019.jpg
1. Redundancy Response
In the response of API /jobs/:jobid, the id and name in both plan and the
vertices data are exactly the same, it would waste a lot of network bandwidth
if the vertex graph is very big(1000+ vertex in a job).

2. Redundancy Request
In the current Web UI design, we have to query vertex number times to display
the low watermarks in the job graph. If the vertex number is very large(1000+
sometimes), the Web UI will send 1000+ request to the REST API, the max
concurrent HTTP request in a browser is limited, it would bring a long time
delay for users.
