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.

從 issue 中連結的自訂 collector 文件以及用戶端的 ASGI 支援開始。追蹤 collect() 的呼叫方式，並將該路徑與 asyncpg 的需求進行比較。完成標準是確認並記錄是否支援非同步收集，或是在不支援的情況下定義用戶端所需的行為。
