v1.40.0

[romange]

Dragonfly v1.40.0

This is one of our biggest releases yet—both in terms of feature quality, total contributions, and the highest number of external contributors in the last two years.

This release delivers major new functionality alongside a large body of correctness and stability fixes for tiered storage, replication, pub/sub, and the experimental V2 I/O loop.

We added a new data type: Cuckoo Filters (CF.RESERVE, CF.ADD/ADDNX, CF.EXISTS/MEXISTS, CF.INSERT/INSERTNX, CF.INFO/COUNT/DEL/COMPACT, and RDB persistence). This brings Dragonfly to parity with RedisBloom's probabilistic structures alongside expanded Bloom filter (BF.INFO) and HyperLogLog support.

Vector search gains native-width storage across all vector dtypes, EPSILON-tuned HNSW range queries, and EF_RUNTIME control. Meanwhile, a long list of fixes hardens tiered-storage interactions with strings, hashes, lists, bitops, and HLL commands, in addition to several replication-consistency fixes around lazy TTL expiry. Performance work includes lazy lock-table registration, zero-copy GET, and replica-side command batching.

• New Cuckoo Filter data type with full command set and RDB support.
• Vector search now stores/computes at native declared width, plus EPSILON and EF_RUNTIME tuning for HNSW.
• Numerous tiered-storage and replication consistency fixes (HLL, hashes, lists, bitops, hash-field TTL expiry).

Highlights

• Added a full Cuckoo Filter data type with RDB persistence, bringing RedisBloom parity for probabilistic structures (feat: add cuckoo_family.cc and cf.reserve  #7646, chore: cuckoo rdb support #7700).
• Vector search now stores/computes vectors at native declared width instead of always widening to FLOAT32, reducing memory usage (feat(search): store & search vectors at native width (FLAT + HNSW, all dtypes) #7849).
• Re-synced hyperloglog.c with upstream Valkey, fixing CVE-2025-32023 and adding AVX2/NEON kernels [up to ~29x speedup on dense HLL merges] (chore(hll): sync hyperloglog.c with valkey upstream #7961).

Commands

• SAVE and BGSAVE now support a HELP subcommand (Add SAVE HELP output #7865).

• Added EPSILON parameter for HNSW-backed VECTOR_RANGE queries to control overscan/recall near the radius boundary (feat(search): support EPSILON for HNSW vector range search #7718).
• Added support for KNN query attribute block syntax (=>{$EF_RUNTIME: ...; $YIELD_DISTANCE_AS: ...}) (feat(search): support KNN query attributes #7708).
• Fixed filtered KNN vector search to serialize only actual winners instead of every pre-filter match, cutting CPU/memory overhead (fix(search): serialize only KNN winners for filtered vector search #7670).

Cuckoo Filter

• Added CF.INSERT and CF.INSERTNX for bulk insertion, with optional CAPACITY and NOCREATE (chore: add cf.insert and cf.insertnx #7719).
