LMDB
An embedded key-value store organized as a B+ tree, using memory mapping for zero-copy reads and supporting an MVCC concurrency model and ACID transactions. It is commonly used for low-latency local state storage.

DUMEdb uses memory-mapped LMDB storage (dumedb.mdb) underneath, achieving sub-microsecond zero-copy register reads.
LMDB is an embedded key-value store library organized as a B+ tree, originally developed by Symas for OpenLDAP.
LMDB uses a single-writer, multiple-reader MVCC concurrency model: read transactions take no locks and see a consistent snapshot, while write transactions commit serially, guaranteeing ACID semantics.
