About:
Sdb is a lightweight, on-disk and in-memory hashtable implementation based on the CDB (Constant Database) structure. It provides fast key-value storage with atomic updates and minimal overhead. The tool is designed for high-performance lookups and is used within the radare2 reverse engineering framework.
|
Key Features:
- Ondisk and in-memory key-value storage
- Atomic updates for data integrity
- Minimal memory footprint and high performance
- Simple string-based API for easy integration
|
Use Cases:
- Storing configuration and state data for radare2
- Building fast lookup tables for applications
- Persistent caching for command-line tools
|
Alternatives:
-
sqlite
– SQLite is a full relational database engine, offering more complex querying capabilities but with significantly larger footprint and complexity than Sdb.
-
redis
– Redis is an in-memory data store that runs as a separate service, providing more features like pub/sub and data structures, but requires external dependencies.
