I built a lightweight memory layer for Claude Code
Claude Code memory without Redis—138 lines of diskcache beats 'use a vector DB' conventional wisdom.

Aphelo – A Redis-like store in C++ with Progressive Rehashing
by pranit_garje·Apr 1, 2026·5 points·1 comment
AI Analysis
●●SolidBig BrainNiche Gem
Progressive rehashing kills 200ms pauses, but Redis already does this.
Strengths
- •Distributes O(N) resize work across operations instead of blocking hot path
- •Clear architecture diagrams showing dual-table migration strategy
- •Educational deep-dive on hash table internals most tutorials skip
Weaknesses
- •Redis implements progressive rehashing already with production battle-testing
- •No production benchmarks or clear advantage over established tools

AgentKV – SQLite for AI agent memory (MMAP vector+graph DB)
Single-file mmap storage plus an HNSW vector index and explicit graph edges is an elegant, practical combo — think "SQLite for agent memory" with CRC-32 crash recovery and zero-server convenience. The C++20 core + nanobind gives zero-copy NumPy views and GIL-free searches, and the claimed FAISS-like throughput makes this genuinely interesting for local setups; main caveat is build/toolchain friction and how rich the surrounding ecosystem becomes.
