PROFILE
Pengfan Lu
Lu Peng Fan contributed to the arana-db/kiwi repository by developing features that enhanced both data retrieval and storage efficiency. He implemented HSCAN command support for hash data structures, enabling cursor-based iteration with pattern matching and count parameters, which brought Redis-like scan semantics to Kiwi and improved scalability for large datasets. In addition, he upgraded the storage layer by replacing the default rust-rocksdb dependency with a forked version for better compatibility and performance, and optimized write operations by passing WriteBatch references. His work, using Rust and focusing on backend development and database management, demonstrated depth in system-level problem solving.

1 Commits • 1 Features
Jan 1, 2026January 2026 — arana-db/kiwi: Storage Layer Upgrade and Authentication Messaging Improvements. Replaced the default rust-rocksdb dependency with a forked zaidoon1/rust-rocksdb to ensure compatibility and potential performance gains. Updated write operations to pass WriteBatch references instead of values to improve write throughput. Improved authentication message handling for clearer diagnostics and maintainability. All changes implemented under commit 1c6cacde39b660da134169596ffb9a8816c82f17 (feat).

Dec 1, 2025December 2025: Delivered HSCAN support for hash data structures in arana-db/kiwi, enabling cursor-based iteration with optional pattern matching and count parameters. This expands data retrieval capabilities for large hash datasets and aligns Kiwi with Redis-like scan semantics, improving scalability and developer ergonomics for client applications. The work is tracked under commit 280e6b5e6de33243fac4deaa0accf2aa29c4296b (feat(command): support HSCAN command).
