Jark Wu commented on FLINK-15986:
---------------------------------

Hi [~phoenixjiangnan], could you elaborate this a bit more? Where do you want 
to add such an API? 
Currently, we already support {{SET}} command in SQL CLI to set or change 
properties/configurations.

> support setting or changing session properties in Flink SQL

> as Flink SQL is more and more critical for user running batch jobs, 
> experiments, and OLAP exploration, it's important than ever to support 
> setting and changing session properties in Flink SQL.
>  
> Use cases include switching SQL dialects at runtime, switching job mode 
> between "streaming" and "batch", changing other params defined in 
> flink-conf.yaml and default-sql-client.yaml
