For example, word2vec has been used to map a vector space of words in one language to a vector space constructed from another language. Relationships between translated words in both spaces can be used to assist with machine translation of new words.
As LMDB is memory-mapped, it can return direct pointers to memory addresses of keys and values through its API, thereby avoiding unnecessary and expensive copying of memory. This results in greatly-increased performance (especially when the values stored are extremely large), and expands the potential use cases for LMDB.

It is possible to put a value into a variable and later replace it with a new one. An assignment operation modifies the current state of the executing program. [3] Consequently, assignment is dependent on the concept of variables. In an assignment: The expression is evaluated in the current state of the program.
