eDB
eDB is an embedded multi-model database for EmbeddedOS devices, combining SQL, JSON document, key-value, graph, and full-text search capabilities.
What eDB is
eDB is an embedded multi-model database for EmbeddedOS devices, combining SQL, JSON document, key-value, graph, and full-text search capabilities. Its SQLite-compatible SQL subset includes common table creation, data insertion, querying, updates, deletion, and joins. B-tree, hash, and inverted indexes serve the different data models. ACID transactions use write-ahead logging and are described as safe across power failures. AES-256-GCM protects data at rest, with keys derived from an eBoot TPM measurement. Storage options include NOR and NAND flash, eMMC, SD cards, and volatile RAM. The engine footprint is listed as under 64 KB of flash, while database size depends on the storage medium and has been tested to 32 GB. Wear leveling is intended to extend NOR and NAND storage life. eDB runs as an EoS service task, uses eBoot for encryption keys, and supports capability-secured inter-process queries through EIPC. It is MIT licensed, open source, self-hosted, and free forever.
Good
- Supports SQL, document, key-value, graph, and full-text data
- ACID transactions use write-ahead logging
- AES-256-GCM protects stored data
- Runs on several embedded storage types
- MIT licensed and free forever
Watch out
- Designed for EmbeddedOS devices
- Database size depends on storage medium
- Python implementation requires version 3.11 or later
Who it suits
eDB suits developers building EmbeddedOS applications that need persistent sensor logs, model metadata, configurations, device state, or health records. It fits teams seeking a compact, self-hosted database with several data models.
Verdict
eDB offers broad data-model support in a small embedded footprint, with transaction durability, encryption, and multiple storage choices. Its fit depends on using the EmbeddedOS environment and the stated implementation requirements.
