   Production Environment Engine Version	Defaults to the engine version that you selected when you created the Flink SQL task. You can switch the engine version here.
   Development Environment Resource Queue And Engine Version	Defaults to the configuration that you selected when you created the Flink SQL task. Select System Default Configuration or Custom Configuration. System Default Configuration: Uses the same cluster and engine version as the production environment. Custom Configuration: You can select the cluster and engine version for the development environment task. This configuration is not required if your project is in Basic mode.
   Parallelism	Default: 1. Enter any integer greater than 0. A value of -1 indicates automatic inference.
   Task Manager Slots	Default: empty. Enter any integer greater than 0.
   Job Manager Memory	Memory allocated to the Job Manager in the Flink cluster. Default: 1 Gi. Specify a value in bytes or with a unit such as Gi or Mi. For example, 1024000, 1024Mi, or 1.5Gi.
   Task Manager Memory	Default: 1 Gi. Specify a value in bytes or with a unit such as Gi or Mi. For example, 1024000, 1024Mi, or 1.5Gi.
