SnapDB v0.3.2 — Bit-Packed Booleans & Package Reorganization

SnapDB v0.3.2 — Bit-Packed Booleans & Package Reorganization

What's New

🚀 Performance

• Bit-packed boolean storage — Python int bitmask replaces array.array('B'), delivering ~8× memory reduction for boolean columns
• Precompiled struct format — single struct.pack/unpack per row (1.6–1.9× faster encode/decode)

📦 Packaging

• Proper Python package — snapdb/ directory with __init__.py
• pyproject.toml — PEP 621 compliant packaging config
• Test suite — moved to tests/ directory
• Benchmarks — moved to benchmarks/ directory
• Modular architecture — core.py, columnar.py, metrics.py, index.py, query.py, wal.py, document_store.py

📊 Benchmarks

• Comprehensive 5-engine comparison: SnapDB vs DuckDB vs SQLite vs Pure Dict
• DuckDB DataFrame batch insert added
• Bit-packed boolean benchmarks included

✅ Correctness

• 47/47 tests passing
• All v0.2.0 and v0.3.x features verified
