EJDB: Embedded JSON Database Engine
Fast, lightweight JSON database engine library written in C for local storage and querying of JSON documents.
What is EJDB?
EJDB is an embeddable JSON database engine that provides document-oriented database capabilities for applications that need to store and query JSON data locally. It is implemented as a C library that can be easily integrated into applications written in C/C++, and also provides bindings for many other programming languages.
Some key features of EJDB include:
- Document-oriented storage of JSON data with indexing and fast queries
- Very lightweight - small code footprint suitable for embedding in applications
- Single file or in-memory database support
- Queries use a MongoDB-like syntax
- Supports indexes on any JSON field for fast lookups
- B+ tree indexing for efficient range scans
- ACID transactions with rollback support
- Concurrent reader and writer access supported
EJDB is well-suited for applications that need to store, query and process JSON data locally on devices or servers. Since it is embedded within the application, it eliminates the need to setup and maintain a separate database server process or server infrastructure. It can achieve very high write performance when tuned properly and provides robust data durability and crash resiliency.
