transformation services on indexing node

[VS]

Using ACS 7.1 enterprise version. We have a seperate indexing server where solr 2.0 with local acs is installed which will just be used for tracking/indexing.  Does this local ACS needs transformation services too? 

We do have ATS installed on main nodes which helps with proviews on share but is it required on indexing servers also? With text and pdfs everything is working fine but end-users can upload other types too.

If you have full text indexing enabled with Solr the yes unless you are relying on the local transform service hosted on remote server. Following determines where to go for transform requests

transform.service.enabled=true

transform.service.url=http://transform-router:8095

sfs.url=http://shared-file-store:8099/

localTransform.core-aio.url=http://transform-core-aio:8090/
