--------------------------
Summary: Flink fail to scale!
Key: FLINK-9597
URL: https://issues.apache.org/jira/browse/FLINK-9597
Project: Flink
Issue Type: Bug
Components: Core
Affects Versions: 1.5.0
Reporter: swy
Hi, we found that our Flink application with simple logic, which using process
function is not scale-able when scale from 8 parallelism onward even though
with sufficient resources. Below it the result where is capped at around 250k
TPS. No matter how we tune the parallelism of the operators it just not work,
same to increase source parallelism.
Please refer to "scaleNotWork.png"
1. fixed source parallelism 4, other operators parallelism 8
