> The QueryDatabaseTable processor does not have a way for the user to set the fetch size for the JDBC query. Some drivers (like Oracle) default to a fetch size of 1, which means result rows needs to be fetched one at a time from the database. This can be very slow, an improvement would be to allow the user to set the fetch size for the query.
> NOTE: Some drivers do not support this, either by throwing an exception or ignoring it (the JDBC spec marks it as a "hint to the database", the doc for the property should make this clear and no exception should be propagated through the processor if the attempt to set fetch size is unsuccessful.
