Content metadata extractor and Solr indexing

Hello,

I fully disabled content + metadata indexing on Solr:

#solrcore.properties
alfresco.index.transformContent=false
alfresco.ignore.datatype.1=d:content

After cleaning indexes and restarting Alfresco I can see a huge workload by Transformer engine (AIO) with dozens of transformations in seconds like this:

2025-09-02 18:27:33.111 DEBUG o.a.transform.common.TransformerDebug : e1958765 Finished in 3 ms
2025-09-02 18:27:33.141 DEBUG o.a.transform.common.TransformerDebug : e1958761 Finished in 41 ms
2025-09-02 18:27:33.180 DEBUG o.a.transform.common.TransformerDebug : e1958764 Finished in 62 ms

....

It seems that metadata extractor on Alfresco side continues to be stressed even after fully disabling content indexing on Solr side. Did anyone have experience about that ?

My Stack

Alfresco 7.4.2 (Content Service)
Solr 6 (Search Service)
Transformer core AIO 5.1.3 (Transformer engine)
