SQLite Versions
The first edition of this book coves SQLite version 3.6.23.1. As this goes to press, work on SQLite version 3.7 is being finalized. SQLite 3.7 introduces a new transaction journal mode known as Write Ahead Logging, or WAL. In some environments, WAL can provide better concurrent transaction performance than the current rollback journal. This performance comes at a cost, however. WAL has more restrictive operational requirements and requires more advanced support from the operating system.
Once WAL has been fully tested and released, look for an article on the O’Reilly website that covers this new feature and how to get the most out of it.
