Hi @jiangbaojun,

Thanks for your contribution!

Could you please update this PR with related tests (likely in BedrockAwsConnectionConfigurationIT) and documentation changes?

[ericbottard]

Please use an else branch to make it clear that this is the 3rd exclusive case

[jiangbaojun]

OK, I will update later

Hi @ericbottard,
I had added tests and updated the documentation

[jiangbaojun]

@ericbottard I've finished updating. Could you review it at your convenience?

[jiangbaojun]

@ericbottard I saw you prefixed the title with (R). What does it mean? Is there anything I can do?

Hi @jiangbaojun,
sorry for the confusion. This is a marker to let us remember that this PR was (almost) ready to merge, but as we were in the middle of initiating boot 4.0 support in main, this has been put on hold. Expect this to appear in 2.0.0.M1 soon!
