Struct BackpressureConfig 

Source 
pub struct BackpressureConfig {
    pub exclusive_credits: usize,
    pub floating_credits: usize,
    pub overflow_strategy: OverflowStrategy,
    pub high_watermark: f64,
    pub low_watermark: f64,
}
Expand description

Configuration for backpressure handling.

Fields§

§exclusive_credits: usize

Initial exclusive credits per sender (like Flink’s buffers-per-channel). These credits are always reserved for a specific sender.

§floating_credits: usize

Floating credits shared across all senders (like Flink’s floating-buffers-per-gate). Allocated dynamically based on backlog priority.

§overflow_strategy: OverflowStrategy

Strategy when credits are exhausted.

§high_watermark: f64

High watermark - when queue reaches this %, start throttling. Value between 0.0 and 1.0.

§low_watermark: f64

Low watermark - when queue drops below this %, resume normal flow. Value between 0.0 and 1.0.
