MindB

MindB is an experimental, ultra-fast key–value store focused on high-throughput writes, low-latency point lookups, and simple secondary indexing.

Benchmarks

This repository includes Criterion benchmarks that compare MindB against SQLite (rusqlite) and Sled:

• Batch inserts (small and large)
• Point lookups (hot key)
• Group-commit microbenches (write path)

Run:

cargo bench

Notes:

• Some benches use a durability mode that issues fdatasync on the final sync() per iteration to amortize cost. See DatabaseOptions.fsync_on_commit and wal_max_batch_ops.
• The rusqlite_compare bench includes both buffered and direct I/O variants for MindB and adds Sled for comparison.
