PacingBudget

polars::prelude::cloud::http_rate_limit

Struct PacingBudget 

Source 
pub struct PacingBudget { /* private fields */ }
Available on crate features polars-io and cloud only.
Expand description

Read-only view of the pacing budget including the learned rate-limit signal for internal consumers (e.g., ConcurrencyController). The cells contains learned rates (f64 bits in an AtomicU64), and are updated by the AIMD loop only. Valid for the process lifetime: object store rebuilds can rotate behind the cells rather than replacing them.
