Struct PruningConfig 

pub struct PruningConfig {
    pub pruning_threshold: Option<u64>,
    pub minimum_retention_ms: Option<u64>,
    pub target_retention_ms: Option<u64>,
    pub batch_size: Option<u64>,
    pub max_usage: Option<u32>,
    pub interval_ms: Option<u64>,
    pub pages: Option<u64>,
}

Retention policy for the archival tables. Durations are whole milliseconds, rounded down

Fields

pruning_threshold: Option<u64>

Disk usage, in bytes, above which pruning starts

minimum_retention_ms: Option<u64>

target_retention_ms: Option<u64>

batch_size: Option<u64>

max_usage: Option<u32>

Disk usage in basis points, so 8000 is 80%

interval_ms: Option<u64>

How often the pruner runs

pages: Option<u64>

SQLite pages vacuumed from the freelist per pruner cycle; unused on Postgres
