Re: Known uses of LMDB outside OpenLDAP

Hi

My name is Ethan Hamilton. I work as software engineer for TIBCO Software,
http://www.tibco.com/ .

As part of my current activities, I am evaluating embedded databases for use
in a system of record scenario. LMDB is one of the several good databases that
has picked our attention. There is lots of information available in the
internet but we find lacking, especially when compared with the information
available for other databases like RocksDB, is information about production
uses outside OpenLDAP. Facebook makes a lot of information available about how
they use RocksDB. They also have a lot of other companies presenting in their
meetups on how they currently use (or plan to use) RocksDB.
On http://symas.com/mdb/#projects there are several dozen open source projects listed that all support LMDB either as their primary/only storage mechanism or as an optional mech. Have you already checked them out? 

If not, why do you expect us to do your homework for you?
Facebook has a lot of money to throw around. The OpenLDAP Project is an all-volunteer organization. If you want Facebook-level of propaganda, someone has to pay for it. 


I am seeking information about uses of LMDB in system of record kind of
situations, especially in large, replicated clusters where LMDB is used as the
persistence layer to store mission critical data.
There are plenty of success stories out there in all of the usual developer-oriented web forums.

Plus the assorted random web sites

And naturally that only covers the open source projects - the proprietary products don't tend to like to talk about what's under their covers. 


Thank you in advance,

Ethan
