PickDB

PickDB is an open-source, lightweight, and fast key-value store designed for embedded systems and IoT devices. It is written in C and is optimized for performance and minimal memory usage, making it suitable for resource-constrained environments. PickDB supports various data types, including strings, integers, and binary data, and provides a simple API for basic operations such as set, get, and delete.

One of the key features of PickDB is its persistence mechanism, which allows data to be stored on disk and retrieved efficiently. This is achieved through a custom file format that minimizes disk I/O operations, ensuring fast read and write operations. PickDB also supports data compression, which further reduces the storage footprint and improves performance.

PickDB is designed to be easy to integrate into existing projects, with a minimal set of dependencies and a straightforward API. It is also highly configurable, allowing developers to fine-tune the database to meet the specific requirements of their application. PickDB is released under the MIT license, making it free to use and modify for both open-source and commercial projects.

PickDB is maintained by a small team of developers and contributors, and it has a growing community of users who contribute to its development and provide feedback. The project is hosted on GitHub, where users can find the source code, documentation, and issue tracker. PickDB is a viable option for developers looking for a lightweight, fast, and reliable key-value store for their embedded systems and IoT projects.
