As a matter of fact, things are moving in the LMDB landscape :

There is still some need of a Windows build for LMDB, but still, I think
that would be great to have a partition that uses LMDB. Just for the
sake of consitency.

We just need the builds for the three different platforms we want to
support :
- linux, obviously
- Mac OSX
- Windows

We can embed the lib in our installers. All in all, we are talking about
2 files: the lib itself and the License file.

A Partition is a specific implementation of the LDAP backend based on a
specific DB engine. We have currently a support for JDBM, Mavibot, LDIF
and Oracle partitions.

However, we might change a few more things if we implement a LMDB
partition :
- we would make it the reference implementation
- we would change the LDAP server code to remove all the useless locks,
to have transaction being supported in the AbstractBTreePartition layer

I don't think that is a lot of work, and I do think it worth testing
that in a branch. I'll probably do that this summer.

This sounds nice. 

In my view, we should probably start with the most popular platform like Linux and fallback to the current Java offering on other platforms that we don't support yet due to all kinds of constraints like resources and the library limit. Incrementally we can add to support more and more.

By supporting a partition using LMDB, what did you mean? A partition using LMDB coexists with a partition using other means meanwhile? Thanks for the clarifying.

Regards,
Kai
