The basics of how to set your project and include/reference the Dlls
are there. You should be able to adapt to your IDE. (I currently use
VS2010 for C# sqlite projects.)

In SQLite, tables are stored as a B-tree (indexed by the ROWID, or by
the INTEGER PRIMARY KEY if you have declared one).
When you remove the oldest entry, you get a hole in the first page of
the table. When you add a

I would like to use sqlite as a FIFO buffer. I know this isn't its intended
use, but I a) need its robust storage backend and b) also need to apply and
queries to it (so, it will not be actually used only as a FIFO).
My questions are the following:
- How would sqlite scale as a FIFO buffer

I think I localized the bug - potential query memory use with larger cache
sizes

- created a database and started in a loop 10 times { import 1m
records; run query}
- for each iteration observe the memory use by SQLITE3 process using
task manager
- the mimimum use
TL;DR: If you want ACID at the OS and storage firmware level, expect to buy
expensive server-rated hardware and expect it to be slow.

I'm not even sure why I'm wading into this; glutton for punishment, I guess.
TL;DR: the assumption that a data-journaled file system guarantees the
atomicity of individual write()s is, in my experience, not a valid one.
Unfortunately this isn't really a topic about which one can draw general

First off, SQLite uses write(), not fwrite().
Secondly, I don't think any modern unix-like
UFS is not fully journaled FS it jut keeps the metadata.
With fully journaled File System that keeps metadata and data there is
no possibility to loose unsaved data.
Anything that was handed to fwrite and fwrite returned an OK for it is
backed by the journal.
