Struct RedisEvictionManager 

pub struct RedisEvictionManager { /* private fields */ }

Proactive Redis eviction manager.

Reuses TanCurvePolicy from the memory eviction module for consistent scoring across L1 (memory) and L2 (Redis) caches.

Implementations

impl RedisEvictionManager

pub fn new(config: RedisEvictionConfig, prefix: Option<String>) -> Self

Create a new eviction manager.

pub fn pressure(&self) -> f64

Get current memory pressure (0.0 to 1.0+).

pub fn needs_profile_refresh(&self) -> bool

Check if we need to refresh the memory profile.

pub fn refresh_profile(&self, used_bytes: u64, max_bytes: u64)

Update memory profile from Redis INFO output.

pub fn record_batch_write(&self, bytes: u64)

Record a batch write (updates pending estimate).

pub fn record_key_write(&self, key: &str, size_bytes: usize)

Record a key write (for eviction scoring).

pub fn record_key_access(&self, key: &str)

Record a key access (touch for LRU scoring).

pub fn remove_key(&self, key: &str)

Remove key from tracking (after eviction or deletion).

pub fn needs_eviction(&self) -> bool

Check if eviction is needed.

pub fn get_eviction_candidates(&self) -> Vec<String>

Get keys to evict, sorted by eviction score (lowest first). Returns up to eviction_batch_size keys.

pub fn stats(&self) -> RedisEvictionStats

Get statistics for monitoring.
