How to reuse connections between different accounts?

[Taowyoo]

Use case

I want to scan multiple accounts (100+) in different regions, and I want to reuse TLS connections for each region, which means no matter how many accounts I want to access, the code only creates TLS connections per region.

Problem

For example, I want to make a lot of requests for account A and B in 5 regions. I would expect there are only 5 TLS handshake happened but not.
I already ensure only one SharedHttpClient is created and used in different aws_config::SdkConfig

Question

How could I achieve it or is it possible?

Interesting. I would expect that this would work. Can you send some more code detailing how you set things up? Just a single service right?

Can you also explain how you determined that multiple TLS connections were being established?

Thank you for reply. Finally, after upgrade to use latest version of SDK, there is no too much TLS connections created in our usecase.
