      Description

      The NXP-31855 enables to process rendition request like /@rendition/pdf or /@rendition/thumbnail in a worker node.

      We want the same behavior for the preview adapter (PreviewAdapter) to avoid preview processing on front nodes and use controlled resources (i.e. processed in a dedicated threads pool on worker nodes).
