boltdb vs sqlite: What are the differences?
Boltdb and SQLite are both popular databases used for data storage and retrieval. However, they have some key differences that set them apart in terms of features and functionality.
-
Performance: Boltdb is known for its excellent performance due to its design as an in-memory database. It provides faster read and write operations compared to SQLite, making it suitable for applications with high-performance requirements.
-
Concurrency: Boltdb is designed to support concurrent access by multiple goroutines in a single process. It uses a lock-free structure called MVCC (Multi-Version Concurrency Control) for maintaining consistency. SQLite, on the other hand, supports concurrent access only through serialized transactions, which can lead to potential bottlenecks in highly concurrent scenarios.
-
ACID Compliance: SQLite is a fully ACID compliant database, ensuring data integrity, consistency, and durability. It supports transactions with rollback and commit capabilities. Boltdb, on the other hand, sacrifices ACID guarantees in favor of improved performance. It does not support transactions or provide built-in support for rollback or commit operations.
-
Database Size: SQLite has a smaller binary size compared to Boltdb, making it suitable for embedding within applications with limited resources. Boltdb, although it offers excellent performance, has a larger binary size due to its design choices.
-
Query Language: SQLite provides a SQL-based query language, which allows complex queries and data manipulation operations. Boltdb, on the other hand, does not provide a query language and relies on accessing data through unique keys.
-
Network Support: SQLite supports client-server architecture and can be used over a network with the help of libraries or wrappers. Boltdb, being an embedded database, does not provide built-in network support and is primarily intended for local file-based storage.
In Summary, Boltdb offers better performance, concurrency support, and smaller binary size compared to SQLite. However, SQLite provides full ACID compliance, a SQL-based query language, and network support, making it a better choice for applications requiring transactional guarantees and complex data querying capabilities.
