I am using FMDB to access the standard iOS internal SQLite database, with one db connection shared among multiple threads.
To make it thread safe I’m locking access to the db to one block of code at a time. All works well, although the access to the db is now a bit of a bottleneck, obviously.
My question is: Can I ease this up a bit by allowing simultaneous queries from multiple threads, as long as they are all readonly SELECT statements?
I can’t find an answer anywhere.
You cannot use the same connection to execute multiple queries at the same time.
However, for purely read-only accesses, you can use multiple connections.
