---------------------------------------
Hi [~KishanK]. Can you give some steps to reproduce? Do you believe this is a
Beam problem or is it specifically something that occurred in the Dataflow
service?
Did you choose 2.7 because it is the LTS (long-term support) version? Or would
you be able to try 2.11.0, which has some performance improvements and upgrades
of dependencies? If you are looking for LTS with the upgrades in 2.11 then you
can await 2.7.1
