ShutterDB v0.1.0 — experimental

ShutterDB v0.1.0

Embedded key-value storage for C++20,
with checksummed append-only files, synchronous writes, recovery and manual compaction.
MIT licensed. On-disk format v1.

Included

• Binary keys and values, tombstones and an in-memory key index.
• Sync-by-default writes, optional buffering and explicit synchronization.
• CLI for text and binary I/O, JSON diagnostics, verification and recovery.
• Static library with CMake install/export and FetchContent support.
• Source and Linux/Windows x64 packages, SHA-256 sums and file manifests.

Fixes

• Preserve an unsupported-format primary when a compaction backup exists.
• Reject FIFO inspection without blocking.
• Reject out-of-order sequences in incomplete final records.
• Include incomplete-tail categories and offsets in JSON verification output.
