streamStats.maxBytesAccumulated

• 类型：<bigint>

在流的整个生命周期中，接收缓冲区中累积的字节数的峰值。这个值只会单调增加。它有助于判断流是否经历过背压，以及累积缓冲区的大小是否适合工作负载。

🌐 The peak number of bytes that were accumulated in the stream's receive buffer at any point during the stream's lifetime. This value only increases monotonically. It is useful for diagnosing whether a stream experienced backpressure episodes and whether the accumulation buffer sizing is appropriate for the workload.
