Anyway, closely related question: In the Talend Components Reference Guide on p. 1834, it is written for tJDBCOutput that it supports dynamic schema. This might be a solution for us, even when the JDBC component version is a little bit slower. However, when I check my supportDynamic.txt, tJDBCOutput isn't listed and it also really doesn't work for me.
So is there a mistake in the reference guide?
