vsdb

vsdb is a high-performance, embedded database designed to feel like using Rust's standard collections. It provides persistent, disk-backed data structures (Mapx, MapxOrd) with a familiar, in-memory feel, plus Git-model versioned storage (VerMap) with branching, commits, merge, and history.

For a detailed guide and API examples, see the vsdb crate documentation. For the versioned storage architecture (VerMap internals, merge algorithm, COW B+ tree, etc.), see the Versioned Module — Architecture & Internals.

Crate Ecosystem

The vsdb project is a workspace containing several related crates:

Crate	Version	Documentation	Path	Description
vsdb			strata	High-level, typed data structures (e.g., Mapx, MapxOrd). This is the primary crate for most users.
vsdb_core			core	Low-level implementations, including the RocksDB storage layer and raw data structures.
vsdb_slot_db			utils/slot_db	A skip-list-like, timestamp-based index for efficient paged queries.
vsdb_trie_db			utils/trie_db	An out-of-the-box Merkle Patricia Trie (MPT) implementation.

Important Changes

• Performance-focused API: The insert() and remove() methods no longer return the old value, eliminating expensive read-before-write operations and significantly improving write performance.
