TITLE: Alluxio: A Memory-Speed Virtual Distributed Storage System

Alluxio, formerly Tachyon, is an open source memory speed virtual distributed storage system. In this talk, I will first introduce the Alluxio project and then describe the Alluxio architecture, focusing on two of its distinguishing features: tiered storage and unified namespace. Tiered storage provides applications running on top of Alluxio with the ability to store data in local storage tiers (memory, SSDs, and hard drives), transparently managing data based on pluggable policies. Unified namespace provides applications running on top of Alluxio with the ability to access data from heterogenous set of remote storage systems (such as HDFS, S3, or GCS) through the same API and namespace.

Prior to working on Alluxio, he was a software engineer at Google, where he worked on a framework for the Internet of Things. Jiri is a CMU and PDL alumnus, earning a PhD for his work on automated testing of concurrent systems under the guidance of professors Garth Gibson and Randy Bryant.
