benwtrent opened a new issue, #14214:
URL: https://github.com/apache/lucene/issues/14214

   ### Description
   
   Connect components on Flush or merge, while good for graphs that are "almost 
OK" but need to be better connected, can just destroy performance if the vector 
distribution is poor. 
   
   I don't readily have test data, but if you have tightly clustered, or many 
duplicate vectors, it can take until the "heat death of the universe" to 
complete. 
   
   It seems to me that since connect Components is a "best effort fix up" of 
the graph, we should add a "cap" on the amount of work this does.
   
   Marking as a bug as I have seen this for real users and it effectively takes 
a CPU hostage for hours (maybe days).
