Struct s3_algo::RequestConfig

pub struct RequestConfig {
    pub timeout_fraction: f64,
    pub backoff: f64,
    pub n_retries: usize,

    pub min_timeout: f64,
}

General parameters that control timeouts and retries

Fields

timeout_fraction: f64

Timeout is set to a fraction of expected upload time (> 1.0)

backoff: f64

Every retry, the timeout is multiplied by backoff (> 1.0)

n_retries: usize

Number of times to retry a single request before giving up

expected_upload_speed: f64

Expected upload speed in MBps (megabytes per second) - used as an initial estimate.

avg_power: f64

To estimate the upload speed incrementally, we use an exponential average: new_avg_speed = avg_power * new_speed + (1 - avg_power) * avg_speed.

Thus, between 0.0 and 1.0, closer to 1.0 means that newer data points have more significance.

avg_min_bytes: u64

Only results from uploads larger than avg_min_bytes are used to estimate upload speed. Uploads with size below this threshold get timeout set to min_timeout.

min_timeout: f64

The minimum timeout (seconds) (always added as an extra term to the total timeout)
