Hi, The problem in your case is that you exit before anything is printed out. The method executeInsert executes the query, but it does not wait for the query to finish. Therefore your main/test method returns, bringing down the local cluster, before anything is printed out. You can e.g. add
TableResult result = transactions.executeInsert("print_table");
result.await();
which will wait for the insert to finish.
The print sink prints into the stdout/stderr directly, therefore none of
the logging configurations apply in this case.
Best,
Dawid
