> In many organizations, when reading from transactional DB systems, it is required to read from tables using the TRANSACTION_READ_UNCOMMITTED transaction isolation level.  The QueryDatabaseTable processor should have an option in the properties to select from a list of transaction isolation levels.  Not all drivers will support all isolation levels, but there should be an option to set this for the one's that do.
