SQLite for Production Use#
SQLite is not a toy database. It handles more read traffic than any other database engine in the world – every Android phone, iOS device, and major web browser runs SQLite. The question is whether your workload fits its concurrency model: single-writer, multiple-reader. If it does, SQLite eliminates an entire class of operational overhead with no server process, no network protocol, and no connection authentication.
WAL Mode#
Write-Ahead Logging (WAL) mode is the single most important configuration for production SQLite. In the default rollback journal mode, writers block readers and readers block writers. WAL removes this limitation.
