- * estore.h -- Expiration Store implementation
- *
- * ESTORE (Expiration Store)
- * =========================
- * 
- * Index-based expiration store implementation. Similar to kvstore, but built
- * on top of ebuckets instead of dict. Items stored in estore must embed an
- * ExpireMeta, enabling efficient active-expiration.
- *
- * Estore is currently used to manage "subexpiry" only for hash objects with
- * field-level expiration (HFE). Each hash with HFE is registered in estore
- * with the earliest expiration time among its fields.
- *
- * USAGE IN REDIS
- * ==============
- * This implementation is used to efficiently track hash objects that have
- * field-level expiration (HFE):
- * - Each hash with HFE is registered with its earliest field expiration time
- * - Enables efficient active expiration of hash fields
- * - Uses Fenwick tree for efficient iteration through non-empty buckets
- * - Supports cluster mode with per-slot buckets
- *
- * IMPLEMENTATION NOTES
- * ====================
- * - Built on top of ebuckets data structure for expiration management
- * - Uses Fenwick tree to track cumulative item counts across buckets
- * - Supports both single bucket (standalone) and multiple buckets (cluster) modes
- * - All operations have O(log n) time complexity for bucket selection
- *
- * STRUCTURE
- * =========
- * - ebArray: Array of ebuckets (one per slot in cluster mode, or just one)
- * - buckets_sizes: Fenwick tree tracking cumulative counts for efficient iteration
- * - bucket_type: EbucketsType defining callbacks for the stored items
