Update C++ wrapper for LMDB? #1

Open artob opened 9 years ago

artob commented 9 years ago

Note that there is now an up-to-date, actively-maintained, and comprehensive C++11 wrapper for LMDB with RAII semantics, in case it might be helpful in your project.

Nice work. I'll give it a go - thanks :)

Thanks Arto. I've not yet had a chance to read lmdb documentation... But I have read the headers! I'm running into problems re. The environment map size being exceeded? I can't seem to find a valid flag to increase it... Nor do I yet know why I need to ;) If you know off hand what the problem is could you let me know otherwise I'll read the lmdb docs when I'm near a computer and have more time!

Cheers

LMDB has a very small default map size (10 MB, I think), so every app needs to explicitly set a larger one. The map size is also the maximum size of the database, so make it large enough...

What you want is lmdb::env#set_mapsize(), which is a wrapper for mdb_env_set_mapsize().

Ah ha! Bingo! Thanks very much. I was looking for a flag when opening or creating the environment.

Thanks for your help!
