Save Input - transform - emit changed Input

Anonymous — Fri, 02 Jan 2026 14:45:42 GMT

Hi ppl,

I'm currently designing my first custom component with the new component kit.

I'm wondering if it's possible to first save all input rows e.g. in an arrayList, edit some rows/elements and later on emit them row by row?
Or do you really have to emit a row every time you reveive one like it works with the @elementlistener?
Hope there is another way to control the output. I would really appreciate some advice!

Thanks in advance
Johannes

Hello,

Here is an advanced tutorial to create an input component: create-an-input-component
In this tutorial the record are buffered so that you can read a bunch of records at once, transform them and then emit them one by one.
The logic is implemented with the BufferizedProducerSupport utility at the end of the tutorial.

Hopefully that helps.
