Framing rules make it impractical to implement http/2 correctly on a single blocking thread. The flow-control features introduce feedback between reads and writes, requiring writes to acknowledge reads and reads to throttle writes.

In OkHttp we expose a blocking API over a framed protocol. This document explains the code and policy that makes that work.

// Buffered input.

// Reader implements buffering for an io.Reader object.
// A new Reader is created by calling [NewReader] or [NewReaderSize];
// alternatively the zero value of a Reader may be used after calling [Reader.Reset]
// on it.
type Reader struct {
	buf          []byte
	rd           io.Reader // reader provided by the client
	r, w         int       // buf read and write positions
	err          error

        }

        // Fill the receive buffer without holding any locks.
        val read = source.read(receiveBuffer, remainingByteCount)
        if (read == -1L) throw EOFException()
        remainingByteCount -= read

        // Move the received data to the read buffer to the reader can read it. If this source has
        // been closed since this read began we must discard the incoming data and tell the
        // connection we've done so.

After Prometheus is configured, you can use Grafana to visualize MinIO metrics. Refer the [document here to setup Grafana with MinIO prometheus metrics](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/grafana/README.md).

## List of metrics exposed by MinIO

- MinIO exports Prometheus compatible data by default as an authorized endpoint at `/minio/v2/metrics/cluster`. 

      Java8Compatibility.clear(cbuf);
      // The default implementation of Reader#read(CharBuffer) allocates a
      // temporary char[], so we call Reader#read(char[], int, int) instead.
      int read = (reader != null) ? reader.read(buf, 0, buf.length) : readable.read(cbuf);
      if (read == -1) {
        lineBuf.finish();
        break;
      }
      lineBuf.add(buf, 0, read);
    }
    return lines.poll();
  }
