Thanks for your reply. Looking forward to it.

some function only accept Stream argument, but we got AsyncRead from somewhere, can someone tell me how to convert it convenient? thx

In our case, we use JavaAgent export metrics without Intrusion into the application code. It will be helpful if the endpoint is configurable when the application has already used /metrics。

@liuzengh but `zapcore.AddSync` returns a fake SyncWriter, right? It doesn't call `file.Sync()`
