@alamb @Dandandan Upgrading Tokio to 0.3 is not as simple as it seems. The runtime is not compatible with the 0.2 one, and it requires to add a compatibility adapter that runs an extra thread (https://docs.rs/tokio-compat-02/0.1.2/tokio_compat_02/). The problem is that many libraries are still running 0.2 (as 0.3 is fairly recent): - tonic: flight is mostly broken because of that - rustoto: not directly used but used by external users (and not just me I guess 😄) What was the reason for upgrading Tokio? If there is no clear reason, I would be in favor of downgrading back to 0.2. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
