@ahmarsuhail since the original PR is merged to trunk and this is backport with clean build and scale testing done, could you please help review/merge so that upcoming 3.3.x or 3.4.0 release doesn't miss it? (otherwise we might have to deal with backward compatibility issues) :)

[ahmarsuhail]

@virajjasani I recently cut the 3.4.0 branch..so I'm just checking where things should be backported to now. Will do this once I have some clarity there.

[virajjasani]

Sounds good, thanks @ahmarsuhail. For branch-3.4, this will be clean cherry-pick since it was just cut recently.

[slfan1989]

@virajjasani Thanks for your reminder! I modified the version to 3.4.0, the PR will be merged to branch3.3 soon. @ahmarsuhail Can you help review this PR? Thank you very much!

[slfan1989]

@virajjasani Thanks for the contribution! merge into branch-3.3.
