A from-scratch, lightweight embedded key-value database in Zig, designed for exploring storage engine internals in a compact codebase, offering core database features with zero external dependencies for experimentation.
This product targets developers requiring highly efficient, low-level data storage solutions, particularly within the Zig ecosystem. Its lightweight nature and zero external dependencies directly address common developer pain points related to bloat and complex dependency management in embedded systems. The inclusion of ACID transactions, WAL-based durability, and B-tree indexing demonstrates a focus on robust core database functionality. Market implications involve potential adoption in specialized applications where resource constraints, performance, and granular control over the storage layer are critical. This positions Kvdb as a foundational component for high-performance, embedded, or systems-level projects, appealing to a niche but growing segment of developers prioritizing efficiency and control.
Hi HN,I’ve been building a small embedded key-value database in Zig:https://github.com/lispking/kvdbIt’s a from-scratch project meant to explore storage engine internals in a compact codebase. Right now it has:* B-tree indexing* WAL-based durability and crash recovery* ACID transactions* 4 KB page-based storage* in-memory page cache* zero external dependencies* a CLI for basic operationsI also added prebuilt binaries and a simple Zig API.Still very early, but usable enough for experimentation. I’d especially appreciate feedback on the storage/WAL design and what would make a project like this more compelling to other Zig developers.Thanks.
