Supports fully serializable transactions with MVCC, ensuring data consistency and safe concurrent reads without corruption, as highlighted in the README's focus on reliability.

Runs as a library within your Go application, stored as a single file for easy deployment and backups, eliminating network overhead and server management.

Uses a B+tree structure enabling fast prefix and range queries via cursors, making it ideal for sorted data iteration and sequential access.

Read-only transactions return direct references to memory-mapped data, reducing allocation overhead and improving performance for read-heavy workloads.
