> they are ultimately based on Tokio's channel mechanism, which relies on Linux's epoll, so it's still very efficient I'm pretty sure that's not the case. There are no file descriptors involved in this as far as I can tell, it's just a bunch of user-space mpsc queues and semaphores (see implementation of `RecordBatchReceiverStream`, `tokio::sync::mpsc::Receiver`, and `tokio::sync::mpsc::Chan`). Kernel-based polling isn't involved here. -- This is an automated message from the Apache Git Service.
