[Talend Component Kit] Create component without input/output

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

I have the need to create a custom component, which does neither emit nor process anything, similar to the component tDBConnection. Is this possible with the new Talend Component Kit?

If I use an Emitter, it says "Missing output connection for ..."

Hi @yoadey ,

This does not exists and any component must be connected to data somehow.

There are a few points to consider:

1. connection like components will likely be supported by the studio at some point (see https://jira.talendforge.org/browse/TUP-21090)

2. the challenge with such components is that they are not meaningful in the job in big data environment (it is not an actual node but a virtual component propagating its content to other components)

3. a trivial workaround is to emit some data (kind of summary)

Hope it helps,
