Struct TailCutLayer

pub struct TailCutLayer { /* private fields */ }

Layer that automatically cancels long-tail requests.

This layer monitors request latency distribution and cancels requests that are significantly slower than the historical baseline (e.g., slower than P95).

This layer should be created via TailCutLayer::builder() and can be cloned to share statistics across multiple operators.

Examples

use opendal::layers::TailCutLayer;
use std::time::Duration;

let layer = TailCutLayer::builder()
    .percentile(95)
    .safety_factor(1.3)
    .window(Duration::from_secs(60))
    .build();

let op = Operator::new(services::Memory::default())?
    .layer(layer)
    .finish();

Implementations

impl TailCutLayer

pub fn builder() -> TailCutLayerBuilder

Create a builder to configure the layer.

pub fn new() -> Self

Create a layer with default settings.

This is equivalent to TailCutLayer::builder().build().
