TITLE:: The Design and Implemention of the Inversion  
        File System 
DATE:: April 1993 
AUTHOR:: Olson, Michael A. 
PAGES:: 34
ABSTRACT:: This paper describes the design, implementation,
and performance of the Inversion file system. Inversion 
provides a rich set of services to file system users, and 
manages a large tertiary data store. Inversion is built
on top of the POSTGRES database system, and takes advantage
of low-level DBMS services to provide transaction protection,
fine-grained time travel, and fast crash recovery for user  
files and file system metadata. Inversion gets between 30%
and 80% of the throughput of ULTRIX NFS backed by a non-
volatile RAM cache. In addition, Inversion allows users 
to provide code for execution directly in the file system
manager, yielding performance as much as seven times better
than that of ULTRIX NFS.
