BackpressureMetrics

mz_persist_client::internal::metrics

Struct BackpressureMetrics 

Source 
pub struct BackpressureMetrics {
    pub emitted_bytes: IntCounter,
    pub last_backpressured_bytes: UIntGauge,
    pub retired_bytes: IntCounter,
}
Expand description

Metrics for the persist_source backpressure operator, summed over every instance of the operator in the process. Like SinkMetrics, these belong to a dataflow operator rather than the client, but the client owns the only registry the operator can reach.

Fields§

§emitted_bytes: IntCounter

Bytes emitted by backpressure operators.

§last_backpressured_bytes: UIntGauge

Sum over live operator instances of the inflight bytes each one most recently stalled on. Instances contribute deltas, so the sum stays exact as operators start and stop.

§retired_bytes: IntCounter

Bytes retired by processing downstream of backpressure operators.
