SQLite is all you need for durable workflows (obeli.sk)

Article summary

The article argues that SQLite can be sufficient for durable workflows, especially for AI agents and experimentation workflows, by providing transactional durable state without introducing a separate database service. It also mentions Litestream, which can stream SQLite changes to S3-compatible object storage for backup and migration. This approach can be a good fit for systems that don't require high availability or broad shared scalability. The article also notes that Postgres may be a better choice when higher availability or scalability is needed.

What commenters say

• SQLite is a suitable choice for durable workflows, especially when combined with Litestream for backup and migration.
• Using SQLite for durable workflows can be more efficient and simpler than using Postgres or other databases.
• Litestream's asynchronous replication may not be suitable for all use cases, particularly those requiring high availability or synchronous replication.
• Temporal is a viable alternative for workflow management, offering a rich and flexible interface for agents to work with, but may add overhead and complexity.
• SQLite's durability and performance make it a better choice than using JSON or Markdown files for large datasets or complex queries.
• The choice between SQLite and Postgres depends on the specific requirements of the system, including availability, scalability, and performance.
• Some commenters have had positive experiences with Temporal, while others have found it adds complexity and overhead without sufficient benefits.
• The use of SQLite or other databases for workflow management can be influenced by factors such as data size, query complexity, and the need for retries and observability.
