Open Source Global Tech Leadership Meetup

Global Tech Leadership Conference *

Open source software always plays critical role in software development. From Linux kernel to TensorFlow, it drives a lot of awesome projects which created trend and led direction of technology.
We are pleased to have several experts, Reynold Xin, Dongxu Huang, Qing Han, Bin Fan, Amelia Wong, etc. who will share the technology and stories on their successful open source project.

Two Ways to Keep Files in Sync Between Alluxio and HDFS

Alluxio provides a distributed data access layer for applications like Spark or Presto to access different underlying file system (or UFS) through a single API in a unified file system namespace. If users only interact with the files in the UFS through Alluxio, since Alluxio has knowledge of any changes the client makes to the UFS, it will keep Alluxio namespace in sync with the UFS namespace.

China Unicom Uses Alluxio and Spark to Build New Computing Platform to Serve Mobile Users

China Unicom is one of the five largest telecom operators in the world. China Unicom’s booming business in 4G and 5G networks has to serve an exploding base of hundreds of millions of smartphone users. This unprecedented growth brought enormous challenges and new requirements to the data processing infrastructure. The previous generation of its data processing system was based on IBM midrange computers, Oracle databases, and EMC storage devices. This architecture could not scale to process the amounts of data generated by the rapidly expanding number of mobile users. Even after deploying Hadoop and Greenplum database, it was still difficult to cover critical business scenarios with their varying massive data processing requirements.

Tachyon: Past, Present and Future

Bay Area Meetup *

Tachyon is a memory-centric fault-tolerant distributed storage system, which enables reliable file sharing at memory-speed. It originated from AMPLab, UC Berkeley in 2012, the same lab produced Apache Mesos and Apache Spark. Soon later, it became an open source project and is deployed at many companies. Since then, Tachyon has attracted more than 200 contributors from over 50 institutions. In 2015, company Tachyon Nexus was founded to further accelerate the development of Tachyon. In this talk, we will review Tachyon’s new features, deployments, and developments in 2015, and look into 2016.

Unified Namespace and Tiered Storage in Alluxio

Strata+Hadoop World San Jose *

Calvin Jia and Jiri Simsa explain how the current Alluxio tiered storage can be easily configured to use memory, SSDs, and hard drives in different tiers. Alluxio users and administrators do not have to manually migrate the data because data in Alluxio is managed transparently between all the configured tiers, similar to the way the CPU manages L1, L2, and lower-level caches. Meanwhile, Alluxio also provides users fine-grained control of manipulating data to plug in their own data-management strategies; users can also pin files in Alluxio to a specific storage or specify a TTL to files. Calvin and Jiri also describe the interface for managing heterogeneous data sources into the Alluxio namespace, which takes advantage of Alluxio’s ability to interoperate with different underlying storage systems such as HDFS, S3, GlusterFS, or Swift.

Alluxio (formerly Tachyon): Open Source Memory Speed Virtual Distributed Storage System

Data by the Bay San Francisco *

The goal is to make Alluxio accessible to an even wider set of users through a focus on security, new language bindings, and further increased stability. In addition, the team is working on new APIs to allow applications to access data more efficiently and manage data across different under storage systems.

Alluxio (formerly Tachyon): New Features and Demos

Bay Area Meetup *

Big data ecosystem is moving with massive energy, customers are from healthcare, retail, transportation, and other fields are benefiting significantly from the business insights derived. As the data growth continues, storage technologies and distributed memory systems are becoming even more important for real time decision making and insight discovery. Intel is excited to work with developer communities on Alluxio and to optimize Alluxio solutions on Intel platform. In this talk, Ziya will discuss Intel’s optimization work in the area, open source contribution and industry use cases.

Past, Present and Future of Alluxio [Chinese]

Shanghai Meetup *

The Alluxio project has greatly improved system performance, Scalability and user experience, and added a series of new features, including scalable tiered storage, transparent UFS data reading and writing, unified namespaces, and more. Easy to use with Alluxio. At the same time, the Alluxio ecosystem has expanded to support different storage systems and computing frameworks. Alluxio now supports a variety of storage systems, including Amazon S3, Google Cloud Storage, Gluster, Ceph, HDFS, NFS and OpenStack Swift, as well as big data processing frameworks such as Spark, MapReduce, Flink and more. These integrations allow Alluxio to manage and help with more and more complex data.
