   >  I’m finding that each paraallel instance waits for a lock and is blocked 
even though partitions being updated are different.
   
   that's by design behavior. if your parallel instances are updating in 
different partition, Hudi still need a lock for the timeline, hence they can 
not change metadata at the same time
   
   but I don't think your application should wait that long since changing 
metadata is a very quick operation, and Hudi won't acquire the lock before it. 
I suppose the lock didn't release correctly.  Have you tried any other lock, 
such as ZkLock or Filelock?
