Difference between Session Mode and Session Job(Flink Opearator)

[bat man]

Hi,

I want to understand the difference between session mode and the new
deployment mode - Flink Session Job which I believe is newly introduced as
part of the Flink Operator(1.15) release.
What's the benefit of using this mode as opposed to session mode as both
run sessions to which flink jobs can be submitted.

Cheers.
H.

Hi!

The Flink Kubernetes Operator on a high level supports 3 types of resources:

   1. Session Deployment : Empty Flink Session cluster
   2. Application Deployment: Flink Application cluster (single job /
   cluster)
   3. Session Job: Flink Job deployed to an existing Session Deployment.

So in other words, the Session deployment only creates the Flink cluster.
The Session job can be deployed to an existing session deployment and it
represents an actual Flink job.

I hope that helps :)
