Amplab-Tachyon [1] is a fault tolerant distributed file system enabling 
reliable file sharing at memory-speed across cluster frameworks. 

== Detailed Description ==
Amplab-Tachyon is a fault tolerant distributed file system enabling reliable 
file sharing at memory-speed across cluster frameworks, such as Spark and 
MapReduce. It achieves high performance by leveraging lineage information and 
using memory aggressively. Amplab-Tachyon caches working set files in memory 
thereby avoiding going to disk to load datasets that are frequently read. This 
enables different jobs/queries and frameworks to access cached files at memory 
speed. 

== Scope ==
* Proposal owners: Currently our Amplab-Tachyon package has been accepted into 
Fedora. It should feature all of the functionality available from the upstream 
release. 
* Other developers: N/A (not a System Wide Change) 
* Release engineering: N/A (not a System Wide Change) 
* Policies and guidelines: N/A (not a System Wide Change)
