SQLite is not a toy database
SQLite is a versatile, serverless database management system that supports advanced features, efficiently handles large datasets, and is suitable for small web applications, countering misconceptions about its limitations.

SQLite is a widely used database management system (DBMS) that is often underestimated as a "toy" database. It is serverless and can be embedded directly into applications, making it accessible for developers, data analysts, and product managers. SQLite supports a variety of features including a powerful console for data analysis, native JSON handling, Common Table Expressions (CTEs), and advanced statistical functions. It allows for easy import and export of data in multiple formats such as CSV, JSON, and SQL. SQLite can efficiently handle large datasets, with performance metrics showing it can process hundreds of thousands of records per second. Contrary to the belief that it is unsuitable for web applications due to limited concurrent access, SQLite can effectively manage multiple readers and a single writer, making it a viable option for small websites. Additionally, it supports full-text search, document storage, and can even function as a graph database. Overall, SQLite is a robust tool that can compete with larger DBMSs in terms of features and performance.
- SQLite is the most common DBMS and is serverless, making it easy to integrate into applications.
- It supports advanced features like JSON handling, CTEs, and statistical functions.
- SQLite can handle large datasets efficiently, with high performance in data processing.
- It is suitable for small web applications, countering the myth of its limitations in concurrent access.
- The database can also function as a document and graph database, offering versatile data management options.

First Contact with SQLite
The article explores surprising aspects of SQLite, like limitations in altering columns and data types. It notes the recent jsonb support and handling date/time values, praising SQLite's streaming features but favoring PostgreSQL.
Gotchas with SQLite in Production
SQLite is popular for web apps but has limitations like single-threaded access, network challenges, and constraints in concurrency and transactions. Consider alternatives like MySQL for complex scenarios.
SQLite: 35% Faster Than the Filesystem
SQLite outperforms traditional file I/O by achieving 35% faster reads of small blobs and using 20% less disk space for 10-kilobyte blobs, despite some latency issues in specific scenarios.
Many Small Queries Are Efficient in SQLite
SQLite efficiently manages numerous small queries without performance degradation, unlike traditional databases. Its architecture supports both complex and simple queries, with page generation latency typically under 25 milliseconds.
Appropriate Uses for SQLite
SQLite is a lightweight, serverless database engine ideal for local data storage in embedded systems, supporting low to medium traffic websites, data analysis, and serving as a cache, but unsuitable for high concurrency.
8 commentsOriginally my goto for databases has been SQL Server or MySQL (depending on what I need to do or use) even on my development machine. Now, I jump straight in with sqlite.
I wrote a program which was storing data in files. I moved it over to sqlite for the query abilities. It was sooo much faster and easier to maintain.
Good little product that packs a punch!
Of course that's not at all true, SQlite is an incredibly robust production-grade tool that is deployed to billions of devices, but it sure feels like that caused damage to the brand.
That said I think this is actually becoming less of an issue these days. Certainly feels like there has been a resurgence in SQLite appreciation and usage over the past few years.
No ability to rename columns. Compared to PG DML, it’s quite restrictive.
Not a toy, but plenty of gotchas
for the 1% or if you don't wanna deal with the well-documented quirks - then yeah reach for the big guns.
