    Would be great if you can be consistent with parenthesis. Sometimes it is 
`explainSource()` and sometimes `explainSource`.

>          Issue Type: Improvement
>          Components: Table API & SQL

> Not all table sink and sources have proper names. Therefore, they are 
> displayed as "Unnamed" in the logs and Web UI (e.g. CsvTableSink). We should 
> add names for all built-in connectors. Having information about the table 
> sink name (via {{INSERT INTO}}) would be even better.
