We have not done this in the past. We are trying to create a SQLite
database to use as a project file for software we're developing. The test
project I linked to in the initial email is one we were able to first make
work with MS SQL Compact, but it has limitations that we want to avoid.

Hello,
we plan to port the SQLite library on an embedded system, which runs on a
platform other than the ones that are supported out of the box (it’s an SMX
based system). For the first step, we don’t need a working mutex subsystem,
because we have no multithreaded environment. The required

No, it does not. Using SQLite covers Virtual Tables in great detail, but not
VFS systems. They’re somewhat unusual, after all.
I assume you’ve read the VFS docs: http://www.sqlite.org/vfs.html
From there, my suggestion is to look closely at the code for the VFS structure

It looks like a standard POXIS implementation. My guess is that the best place

Hi,
What kind of compression is used with the experimental FTS5? I¹d be
interested to hear about real world comparisons in regards to compaction
and performance.
