Enum Class SessionMetrics.CacheEvictionReason

java.lang.Object

java.lang.Enum<SessionMetrics.CacheEvictionReason>

at.aimon.session.web.metrics.SessionMetrics.CacheEvictionReason

All Implemented Interfaces:

Serializable, Comparable<SessionMetrics.CacheEvictionReason>, Constable

Enclosing interface:

SessionMetrics

public static enum SessionMetrics.CacheEvictionReason
extends Enum<SessionMetrics.CacheEvictionReason>

Why the local session cache dropped an entry. Maps from Caffeine's RemovalCause.

Note: Caffeine reports EXPLICIT uniformly for invalidate() regardless of intent — the manager cannot distinguish a releaseConversation() from a cross-node EVICT-triggered eviction at the cache layer. Operators wanting that breakdown should correlate SessionMetrics.onHolderLossRecovered() with eviction counts.
