Since the emergence of commercial applications decades ago, databases have become a major component of software applications. Just as database management systems are critical, they also become very large and occupy a considerable amount of system resources, increasing management complexity. As software applications gradually modularize modules, a new type of database is more suitable than a large and comple

. In other words, the change is actually serialized, and because there is no blocking between the different changes, the MVCC scheme consumes more compute resources (all failed commits are re-made). As a result, Lmdb has serialized all the change operations with a lock. These are the most important points in lmdb implementation.
