Beginning with version 3.3.0, you will be able to configure SQLite
so that multiple connections running in the same thread will be
able to select READ UNCOMMITED isolation relative to one another.
Note that this will only be possible for connections in the same
thread - it will not be possible for connections in different
threads of the same process. With READ UNCOMMITTED isolation,
you can still only have a single connection writing to the database
at a time, but writers will not block readers nor will readers block
writers. This allows a much higher level of concurrency.
I was wondering if there is an alpha/beta build of 3.3 available or if
anyone knows when this version/fix might be available?
