Pika 3.0 Main New Features

1. Brand‑new Blackwidow engine

1. Multiple interfaces see significant performance improvements.

2. The new engine occupies less disk space for the same data.

3. No longer limited to a 256‑byte key length for complex data structures.

4. ZSET structure with precision identical to Redis.

2. New binlog (write‑to‑file)

1. Higher parsing efficiency.

2. Smaller size, more friendly to disk space.

3. Supports multiple version formats that are mutually compatible, eliminating upgrade hassles.

3. More efficient server layer

1. Optimized call efficiency between server and engine layers.

2. Redundant code removed and logic refined to boost overall server performance.

3. Server code is now easier to read, though still not poetic.
