You probably need to take a closer look at the client/driver you are using and the code that interacting with it.
In fact I would say you need to review the entire data transfer process to see if there are performance gains that can be obtained without adding an entirely new async component.
You were spot on. When we turned off the "auto commit" we started seeing less number of commits as per the number of batches.
However we also started seeing deadlock issues. We have foreign key relationships between the tables and during the batch we do insert into the parent first and then to the child , but this does happen from multiple sessions for different batches. So why do we see below error, as we ensure in each batch we first insert into parent and then into the child tables?
