Reader --> T1 ---------->Aggregator -> Writer
| |
-> CT1 -|
-> CT2 -|
Every feature has an "id" and the aggregator groupd them with the "id"
T1 is a simple transformer (like AttributeCreator).
CT1 and CT2 are custom transformer very complicated with many steps (~20 each without the same length).
Because i've got ~1million element in the Reader, in the Aggregator I which I could select the "Input is ordered by group" for "performance" issues.
But it does not work; I've got only the T1 output.
So, How may I do this ?
For feeding the pipe I though of "no-op" block like in electronic ... but it's does not exist and it's a pain to do.. and not very reliable.
Is there something else I could do / use ?
