Announcing D1: our first SQL database
We announced Cloudflare Workers in 2017, giving developers access to compute on our network. We were excited about the possibilities this unlocked, but we quickly realized — most real world applications are stateful. Since then, we’ve delivered KV, Durable Objects, and R2, giving developers access to various types of storage. Today, we're excited to announce D1, our first SQL database. While the w

I'm All-In on Server-Side SQLite Author Name Ben Johnson @benbjohnson @benbjohnson Image by Annie Ruygt I’m Ben Johnson. I wrote BoltDB, an embedded database that is the backend for systems like etcd. Now I work at Fly.io, on Litestream. Litestream is an open-source project that makes SQLite tenable for full-stack applications through the power of ✨replication✨. If you can set up a SQLite database
Consider SQLite
If you were creating a web app from scratch today, what database would you use? Probably the most frequent answer I see to this is Postgres, although there are a wide range of common answers: MySQL, MariaDB, Microsoft SQL Server, MongoDB, etc. Today I want you to consider: what if SQLite would do just fine? For those who are unfamiliar, SQLite is a implementation of SQL as a library — this means t
SQLite is not a toy database
English • Russian • Spanish Whether you are a developer, data analyst, QA engineer, DevOps person, or product manager - SQLite is a perfect tool for you. Here is why. A few well-known facts to get started: SQLite is the most common DBMS in the world, shipped with all popular operating systems.SQLite is serverless.For developers, SQLite is embedded directly into the app.For everyone else, there is

GitHub - lspgn/edge-sql: Cloudflare Workers providing a SQL API
I had an idea. Here's a little backstory. Many services provide a REST API on top of a SQL database. For certain datasources, flexibility in terms of queries is key. Often those use-cases are dashboard prototyping, for example with Grafana. This data is usually read-only statistical datasets where the user needs to run many queries in order to troubleshoot an issue or just find the best visualizat
SQLite Autoincrement
1. Summary The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. It is usually not needed. In SQLite, a column with type INTEGER PRIMARY KEY is an alias for the ROWID (except in WITHOUT ROWID tables) which is always a 64-bit signed integer. On an INSERT, if the ROWID or INTEGER PRIMARY KEY column is not explicitly given

SQL Features That SQLite Does Not Implement
SQLite implements most of the common features of SQL. Rather than try to list all the features of SQL that SQLite does support, it is much easier to list those that it does not. Unsupported features of SQL are shown below. See also the Quirks, Caveats, and Gotchas of SQLite. Only the RENAME TABLE, ADD COLUMN, RENAME COLUMN, and DROP COLUMN variants of the ALTER TABLE command are supported. Other k
