Hi Raihan, We have encountered the same issue though we are using Flink Kubernetes Operator 1.6. Biao Geng's explanation is correct. We also have a detailed briefing in this jira ticket but it seems that submitting multiple jobs is not allowed b

Hi, Tony. There are some related works in Flink commu to support Redis source / sink connector. You can see more here[1][2][3][4]. However, these JIRAs are still WIP. The good news is that the PR in jira[1] is already available. You can directly download the PR and package it into a conn

Re: Flink Kubernetes Operator Application mode multiple jobs

2024-05-07 Thread Biao Geng
Hi Raihan, I believe the flink k8s operator has some implicit assumption that each application should contain only one job so that it can manage the lifecycle of the job reasonably. Your usage of deploying multiple jobs in a single python file(i.e. in a single flink application) may be not preferr
