# agentgateway service initialization flow


## Initialization flow

Below I describe the initialization flow and the thread model. The main thread types are:

- main thread — thread name: agentgateway
- main spawn thread — thread name: agentgateway
- agentgateway workers — thread name format: agentgateway-N

Reading Rust code that uses Tokio and async can be a bit overwhelming for Rust newcomers. Fortunately I previously learned Go and its goroutines, which makes the concepts easier to grasp. Each OS thread can have a [tokio::runtime::Runtime](https://docs.rs/tokio/1.47.1/tokio/runtime/index.html) bound to its thread-local context (similar to a scheduler with a thread pool). The key is to focus on the code that performs `spawn` operations.
