Common storage-related types

Structs

AppendOnlyFile	Wrapper for a file that can be read at any position (random read) but for which writes are append only. Reads are backed by a memory map (mmap(2)), relying on the operating system for fast access and caching. The memory map is reallocated to expand it when new writes are flushed.
DataFile	Data file (MMR) wrapper around an append-only file.
SizeEntry	Represents a single entry in the size_file. Offset (in bytes) and size (in bytes) of a variable sized entry in the corresponding data_file. i.e. To read a single entry from the data_file at position p, read the entry in the size_file to obtain the offset (and size) and then read those bytes from the data_file.

Are we dealing with "fixed size" data or "variable size" data in a data file?
