SQLite Concurrency WAL
Discussions center on SQLite's handling of concurrent reads and writes across multiple processes or threads, with repeated emphasis on enabling WAL mode to mitigate locking issues and improve performance.

Kind of - your web application needs to partially handle that, and SQLite also depends on the OS filesystem to handle concurrent access.
You'll want to turn on write-ahead logging for that scenario[1][1]: https://www.sqlite.org/wal.html
I assume you’re asking about concurrent writes and yes, if you use WAL mode you can have that too.https://www.sqlite.org/wal.html
Yes, but: https://sqlite.org/wal.html
No, because of SQLite's locking mechanism. It uses filesytem-level constructs to support concurrency, and this gets dicey, quickly.
if your data isn't mostly read-only, then you're going to have an issue with SQLite. It doesn't nicely support parallel writers
SQLite in WAL mode would manage for sure.
I think this is mentioned in the docs https://www.sqlite.org/wal.html
SQLite isn't running in WAL mode. This application isn't just read-heavy, it is ready-only for users, so I wouldn't think this will make a difference. The writes occur while everybody is sleeping, from a cron job that runs once a day to upload the traffic for the previous 24 hs.
Were you using wal mode with sqlite? It helps a lot with locking.
