As workloads become more concurrent, however, the default rollback journal can make read and write activity interfere more than expected.</p> <p>Write-ahead logging (WAL) changes that coordination model. Readers can usually continue while a writer commits changes, but WAL does not turn SQLite into a multi-writer database. Correct operation still depends on short transactions, sensible busy handling, and checkpoints that can make progress.</p>
