SQLite simultaneous reading and writing

Question

I\'ve read a lot of topics, but can\'t figure out answer for question: is it possible to read and write simultaneous?

I have background thread that updates some data

Answer 1

You cannot read and write at the same time. SQLite is a serverless, file-based database.

From the SQLite FAQ:

"When any process wants to write, it must lock the entire database file for the duration of its update. But that normally only takes a few milliseconds. Other processes just wait on the writer to finish then continue about their business. Other embedded SQL database engines typically only allow a single process to connect to the database at once."
