%description
|
|
This module provides a facility for efficiently sharing mutable data
|
|
between processes on one host. Data is organised as a key/value store,
|
|
resembling a Perl hash. The keys and values are restricted to octet
|
|
(Latin-1) strings. Structured objects may be stored by serialising them
|
|
using a mechanism such as Sereal.
|
|
|
|
The data is represented in files that are mapped into each process's memory
|
|
space, which for interprocess communication amounts to the processes
|
|
sharing memory. Processes are never blocked waiting for each other. The use
|
|
of files means that there is some persistence, with the data continuing to
|
|
exist when there are no processes with it mapped.
|
|
|
|
The data structure is optimised for the case where all the data fits into
|
|
RAM. This happens either via buffering of a disk-based filesystem, or as
|
|
the normal operation of a memory-backed filesystem, in either case as long
|
|
as there isn't much swapping activity. If RAM isn't large enough, such that
|
|
the data has to reside mainly on disk and parts of it have to be frequently
|
|
reread from disk, speed will seriously suffer. The data structure exhibits
|
|
poor locality of reference, and is not designed to play nicely with
|
|
filesystem block sizes.
