| Description |
|
It would be extremely useful to have a functional backend supporting LMDB, as a replacement for the non-transactional levelDB backend. Having a DB that is ACID (which levelDB is not, since it is missing the I) and a DB that does not need to pause for compaction/garbage collection like levelDB for those of us that care about performance, is critical. |

Performance benchmarks: http://symas.com/mdb/inmem/ leveldb does not scale. |
