09/25/2023, 5:17 PM@Gyula Fóra What's the difference between the Autoscaler (https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-release-1.4/docs/custom-resource/autoscaler/#:~:text=The%20operator%20provides%20a%20job,target%20set%20by%20the%20user.) and Elastic Scaling/Reactive Mode (https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/elastic_scaling/#:~:text=Flink%20will%20manage%20the%20parallelism,for%20manually%20rescaling%20a%20job)
Or are they basically the same thing?
