> {{flink-table}} depends on Apache Calcite which includes a JDBC Driver that prevents classloaders from being collected. This is a known issue with {{java.sqlDriverManager}} and can eventually cause OOME Permgen Taskmanager failures.
> The current workaround is to not include {{flink-table}} in the fat job JAR. Instead the {{flink-table}} jar files should be added to the {{lib}} folder of the TaskManagers.
