godfrey he commented on FLINK-18161:
------------------------------------
[~jark], thanks for the suggestion, but I don't think that could simplify
design. First, If sql-client's configuration accept {{parallelism.default}}, we
also should handle the conflict. Second, when users execute
{{execution.parallelism=12}} and then execute {{set}} command to list all
properties, they find {{execution.parallelism}} does not exist . Last, we must
handle this special case in {{ConfigurationEntry}}.
> Changing parallelism is not possible in sql-client.sh
