Struct WalPullerConfig 

Source 
pub struct WalPullerConfig {
    pub max_appliers: usize,
    pub max_disk_bytes: u64,
    pub applier_cache_kb: i64,
}
Expand description

FD/disk budget + cache-trim knob for a WalPuller’s attached appliers. See the module doc for the chosen Default numbers and their (unmeasured) provenance.

Fields§

§max_appliers: usize

Max concurrently-attached appliers. Each is a live CoreWalSeam — several open FDs — so this is the box’s FD budget, not just a counter; raise the box’s ulimit to match before raising this.

§max_disk_bytes: u64

Max sum of attached appliers’ dest_size_bytes hints. A warm standby is a full local copy of the tenant DB, so this is the box’s local-disk budget (Σ tenant DB sizes), per §5.

§applier_cache_kb: i64

Page cache size (KB) an applier is trimmed to immediately on attach.
