@fhueske @walterddr @suez1224 I added the possibility to make the JVM heap
size configurable. After a short offline discussion with @StephanEwen, I'm not
sure if we should add such configuration to the flink-conf.yaml or in a
separate configuration file. I don't know which configuration we will need in
the future outside of the SQL Client environment files. I don't know if it is
worth to have a separate file just for JVM options. Or we hard code it into the
sql-client.sh script that can be modified by a variable. What do you think?
