Sounds like that must have been an absolute bitch to build. I cannot imagine re-implementing 300 existing API’s for Rust from scratch…

On the plus side, I guess the work lends itself well to parallelization.

A good chunk of the AWS SDKs are codegen’d - it’s the only possible way to support the sheer volume of stuff they need.

Agreed - the Java SDK v2 has had 20 updates this month alone (sometimes two or three times in one day) so definitely not much in the way of manual updates.

As with all the other AWS SDKs, the bulk of the code is generated. The JSON service definitions are shared, the effort (one expects) is in being adding support for all the different ways in which the JSON indicates that services behave, and making it look like it could have been hand-written.
