Hi!

Fully ACK. I think with the recent optimisations KPA is quite fast anyway.

That said, I was just speaking out ideas that came to mind. No need to
implement it.

I'm a hobby photographer with little time, so I'm not taking a lot of
photos. But my first digital images go back to 2003 which leads to a
database with about 50k images. And with recent development of
smartphones, I guess people are taking more and more photos. So being fit
for future is always a good idea.

And BTW, I really think Robert enjoys pushing performance further ;-)

That's true and I didn't say it would be an easy job ;-)

Still, the format should stay almost the same and thus still be
readable/writable by humans. IMHO, if we consider splitting the DB,
moving from one file to another shouldn't be harder as copy/past of
<image> lines.

Anyway, just wanted to share my idea and I really think partitioning the
DB with optionally deferred loading of older partitions could speed up
startup time.
