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.

Benefit to Fedora

Amplab-Tachyon is an exciting project for Fedora as it enables in memory computation speeds for popular big-data frameworks that are part of fedora.
