Expand description

Resource and maintenance limits shared by the storage engine components.

Fields§

§max_memory_bytes: u64

Hard total memory budget for the storage instance.

§index_memory_bytes: u64

Independent budget reserved for native indexes.

§memory_soft_ratio: f64

Ratio at which background maintenance should be scheduled.

§memory_hard_ratio: f64

Ratio at which new work receives a capacity error.

§max_active_snapshots: usize

Maximum number of active snapshot registrations.

§max_snapshot_age: Duration

Maximum age allowed for a snapshot before it is rejected by the owner.

§max_tombstones: usize

Maximum number of MVCC tombstones before backpressure is required.

§max_tombstone_bytes: u64

Maximum estimated tombstone memory.

§index_gc_batch: usize

Number of index entries processed by one incremental GC pass.

§operation_timeout: Duration

Maximum duration for one maintenance operation.

§dirty_flush_operations: u64

Number of dirty operations that triggers a flush request.

§dirty_flush_bytes: u64

Estimated dirty bytes that triggers a flush request.

§cache_ttl: Option<Duration>

Record cache time-to-live.

§cache_tti: Option<Duration>

Record cache time-to-idle.

§spill_threshold_ratio: f64

Ratio of hard_limit at which the disk spiller proactively evicts cold data. Must satisfy soft_ratio < spill_threshold_ratio <= 1.0.

§cache_eviction_sync: bool

When true, every Moka cache eviction immediately decrements the memory accounting counter, eliminating accounting lag between refresh intervals.

§index_pool_capacity_bytes: u64

Per-shard native-index buffer pool capacity in bytes.

§index_eviction_enabled: bool

Enable chunk-level eviction under memory pressure.

§index_eviction_high_ratio: f64

Eviction high-water ratio: trigger eviction when usage/capacity exceeds this.

§index_eviction_low_ratio: f64

Eviction low-water target: evict down to this ratio of capacity.
