Package dev.relism.flash.ext.limiter

Class Bucket

java.lang.Object

dev.relism.flash.ext.limiter.Bucket

public final class Bucket
extends Object

Pre-allocated per-key rate limit state. Holds two AtomicLong slots whose semantics are strategy-specific:

• FIXED_WINDOW: slot0 = packed (epoch << 32 | count), slot1 unused.
• SLIDING_WINDOW: slot0 = packed (epoch << 32 | count), slot1 = request count from the immediately preceding epoch.
• TOKEN_BUCKET: slot0 = tokens × 1000 (scaled), slot1 = last-refill timestamp (ms since epoch).

Buckets are created once per unique key (via BucketStore) and reused for the lifetime of the server — zero allocation on the warm path.
