regarding your troubles with changing the parameters of CloverETL, please see the documentation here: http://www.cloveretl.com/documentation/ ... tings.html
. In short - there's basically two ways:
- modifying the properties file. It can be found in the CLOVER_INSTALLATION/plugins/com.cloveretl.gui/lib/lib/cloveretl.engine.jar file inside the org/jetel/data subdirectory.
- create a small property file of your own, and point the executed graph to it. This is also described in the documentation, but the point is that you need to pass the "-config path_to_your_config_file" to the executed graph. Please take care to pass the correct path, e.g. an absolute path. The file can contain just the one property you want to change, which is Record.MAX_RECORD_SIZE in your case.
Additionally, we're releasing CloverETL version 3.2 early next week, which has greatly improved handling or big records - it's edges can dynamically grow as needed. So in the new version you will almost never need to change the property.
Regarding your issue with string size - this was already encountered by someone else, please see forum post: viewtopic.php?f=4&t=4930
. In short, you can set the field size to empty value - this will not harm you.
