The friendly one is to pass the upstream

Kolpona123

So I chose another medium interaction, that is, just the level, connecting between the tables, and then passing all the upstream fields to the downstream. Field mapping in the lower reaches. How to reflect the corresponding relationship between the field during the mapping process is that the simplest and most unique form is the default mapping from top to bottom.  to the upstream plug -in, display the upstream field inside the downstream plug -in, and then make a field comparison in the lower reaches of the downstream plug -in.


If the fields in the upstream are changed, then when the downstream is obtained from the change of this changing field, this increases a partial preservation or the ability of global preservation to do it. Source end, target end, intermediate conversion plug -in (operator), connect Jiangsu Mobile Number List to the mapping link between the plug -in. It is a complete dragging data integration task. Fifth, whether it is offline or real -time mission, all the operators introduced above are actually introduced from an offline perspective.





But the real -time perspective is actually applicable. It's just that the conversion operator in the middle is different. If this is offline, you can be used as an ordinary offline task, placed in the offline DAG diagram, and configure the scheduling. If it is a real -time, you can directly start and run. 6. t is the process of realizing your own ideas. After the realization of dragging data integration, it is considered a personal goal of making a product. It is still very happy to watch something realize in your own planning。
