[alexellis]

Thank you. Is it still WIP, or ready to merge/test?

[viveksyngh]

This is almost ready and tested but I have not added unit test for this. Will add unit test and push it.

Thanks @alexellis @martindekov

[viveksyngh]

I have added unit test and updated the existing unit tests.

[alexellis]

@martindekov WDYT?

[martindekov]

Thanks for the added unit tests @viveksyngh, @alexellis I think the implementation is good, I will vendor the change in the kafka-connector and possibly the vcenter-connector and try to test them also :+1:

[alexellis]

Thank you 👍 there is a new release ready.
