v0.1.1 — Durability, Benchmarks, and Polish

Fixed

  • WAL durability — writer now fsyncs after every append by default (SyncEvery). Configurable via SyncMode for throughput-sensitive workloads (SyncOnRotate).
  • Snapshot atomicity — snapshot writes now use write-to-temp + rename to prevent corruption on crash
  • WAL replay dedup — duplicate WAL entries (same actor ID + Lamport clock) are skipped during recovery
  • Federation merge — fast path for single-shard search results avoids map allocation

Added

  • DropCollection — remove a named collection and all its data from disk, wired through RPC transport
  • RPCPuller / DBApplier — exported replication adapters for setting up followers without copy-pasting test code
  • SyncMode / ManagerConfig — configurable WAL sync policy for balancing durability and throughput
  • Benchmark suite — Put, Search (1K/10K/100K), parallel search, filtered search, History, Open/Close

Benchmarks

384-dim vectors, 2-bit quantization, Intel Core Ultra 9 285:

Search top-10 (1K vectors) 82us
Search top-10 (10K vectors) 546us
Search top-10 (100K vectors) 5.5ms
Search parallel (10K, 20 cores) 49us/op
Open + Close (1K vectors) 31ms
