Async CustomCollector

So I need to obtain some metrics from a database and I'm planning to create a custom collector as described here: http://prometheus.github.io/client_python/collector/custom/

I use asyncpg to connect to PostgreSQL. My problem though is that asyncpg query needs to be called from an async function and collect() is synchronous.

Is there an async equivalent? It looks like the client supports being used from ASGI.

从 issue 中链接的自定义 collector 文档以及客户端的 ASGI 支持开始。跟踪 collect() 的调用方式，并将该路径与 asyncpg 的要求进行比较。完成标准是确定并记录是否支持异步收集，或者在不支持的情况下定义客户端所需的行为。
