But how, exactly, databases use mmap?
I decided to dig through a database source code to answer that question. There are plenty of databases that use mmap. Some of them decided to not use anymore. Some examples: SQLite has an option of accessing disk content directly using memory-mapped I/O[1], it seems LevelDB used to use but it changed it[2], Lucene has an option with MMapDirectory[3], LMDB uses mmap[4], a simple key/value in-memory database from Counchbase called moss uses mmap for durability of in-memory data[5] and MongoDB removed mmap storage engine for WiredTiger[6].
