No support for mmap_size pragma?

[Andrea Aime]

Hi, 

I'm looking into ways to speed up access to a large-ish sqlite database (a few GB) and found this SQLite documentation page:

https://www.sqlite.org/mmap.html

I have used NIO memory mapping with great benefit in previous Java programs, so I was wondering what effect I could

get my using memory mapping in SQLite.

However, looking at the code I don't see support for mmap_size pragma. Is this intententional for some good reason,

or just an overlooked case?

Cheers

Andrea

Hi,

I've built locally a patched version with mmap support. While it's does not provide a "rocket boost"

it helps some. The patch is real simple, should I make a pull request?

Cheers

Andrea
