Summary: Potential issue in autoscaler algorithm
Key: FLINK-36734
URL: https://issues.apache.org/jira/browse/FLINK-36734
Project: Flink
Issue Type: Improvement
Components: Autoscaler
Reporter: Sai Sharath Dandi
Currently, the autoscaler algorithm tries to keep all the Job vertices at X%
utilization(default 70). However, it is impossible to keep all the vertices at
70% utilization depending on the Job topology (Imagine a long job topology > 10
vertices). The autoscaler algorithm should be smart enough to set a better
default utilization target depending on the topology length. 0.7 *
100/topology_length could be a good starting point
