/// Database documents are stored in memory-mapped files. Per default, these
/// memory-mapped files are synced frequently - storing all documents securely
/// at once (durability).
///
/// @section DbaManualBasicsMvcc AppendOnly/MVCC
////////////////////////////////////////////////
///
/// Instead of overwriting existing documents, a completely new version of the
/// document is generated. The two benefits are:
///
/// - Objects can be stored coherently and compactly in the main memory.
/// - Objects are preserved-isolated writing and reading transactions allow
/// accessing these objects for parallel operations.
///
/// The system collects obsolete versions as garbage, recognizing them as
/// forsaken. Garbage collection is asynchronous and runs parallel to other
/// processes.
