Struct TieredStorage

pub struct TieredStorage {
    hot: InMemoryStore,
    warm: WarmStore,
}

Composite storage that reads from hot first, then warm.

Fields

hot: InMemoryStore

Hot tier (fast, in-memory or RocksDB).

warm: WarmStore

Warm tier (file-based, partitioned).

Implementations

impl TieredStorage

pub fn new(hot: InMemoryStore, warm: WarmStore) -> Self

Create a new tiered storage with the given hot and warm stores.

pub fn hot(&self) -> &InMemoryStore

Access the hot tier directly.

pub fn warm(&self) -> &WarmStore

Access the warm tier directly.

pub fn compact( &self, entity_id: u64, space_id: u32, cutoff: i64, ) -> Result<usize, StorageError>

Migrate points from hot to warm tier.

Moves all points for the given entity+space with timestamp ≤ cutoff from hot to warm storage.

Trait Implementations

impl StorageBackend for TieredStorage

fn get( &self, entity_id: u64, space_id: u32, timestamp: i64, ) -> Result<Option<TemporalPoint>, StorageError>

Retrieve a single point by entity, space, and timestamp.

fn put(&self, space_id: u32, point: &TemporalPoint) -> Result<(), StorageError>

Store a temporal point.

fn range( &self, entity_id: u64, space_id: u32, start: i64, end: i64, ) -> Result<Vec<TemporalPoint>, StorageError>

Retrieve all points for an entity in a time range, ordered by timestamp.

fn delete( &self, entity_id: u64, space_id: u32, timestamp: i64, ) -> Result<(), StorageError>

Delete a specific point.
