ColdStore is a gigabyte-scale persistent object
store which mmap()s objects into a file (for
persistence), can allocate objects in a minimal
working-set of pages (for speed), permits library
versions to change without a rebuild of the store,
permits application checkpoint/restart. ColdStore
might be used to replace a database, cache highly
structured objects, act as an OODB, make STL
persistent, act as a Document Store for
XML/SGML/HTML, create a MUD. Future projects
include a virtual machine toolkit, ports of several
languages, VM and byte-interpretive language
workbench.
