public class BasicDataSourceExt extends org.apache.commons.dbcp2.BasicDataSource
This class exists so that MetadataStorageConnectorConfig is asked for password every time a brand new connection is established with DB. PasswordProvider impls such as those based on AWS tokens refresh the underlying token periodically since each token is valid for a certain period of time only. So, This class overrides (and largely copies due to lack of extensibility), the methods from base class in order to keep track of connection properties and call MetadataStorageConnectorConfig.getPassword() everytime a new connection is setup.
