Moving From Apache Thrift to gRPC: A Perspective From Alluxio

As part of the Alluxio 2.0 release, we have moved our RPC framework from Apache Thrift to gRPC. In this article, we will talk about the reasons behind this change as well as some lessons we learned along the way.
In Alluxio 1.x, the RPC communication between clients and servers is built mostly on top of Apache Thrift. Thrift enabled us to define Alluxio service interface in simple IDL files and implement client binding using native Java interfaces generated by Thrift compiler. However, we faced several challenges as we continued developing new features and improvements for Alluxio.

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.

Unified Data Access In Virtual Reality

In a recent blog, we discussed the ideation, design and new features in Alluxio 2.0 preview. Today we are thrilled to announce another new revolutionary project that the Alluxio engineering team has been hard at work on for the past year – the Alluxio Virtual Reality (VR) client.

Founder Blog | Alluxio Chapter 2.0

In the early 2000s, big data was born, and technology companies were racing to create the next-gen compute frameworks or storage systems geared towards the requirements brought about by big data. By the time I was a first year Ph.D. student at UC Berkeley’s AMPLab in 2011, numerous advances in big data related technologies such as Apache Spark was emerging. Through working on Apache Spark and getting exposed to cutting-edge technologies it became clear that sharing data among data driven applications with different compute frameworks and moving data across storage systems would become the bottleneck for any organization that wants to extract value from their data. To solve these challenges, I created Alluxio (formerly Tachyon), which for the lack of a defined category I called it a virtualized distributed file system in my original thesis.

Getting Started with Spark Caching using Alluxio in 5 Minutes

Apache Spark has brought significant innovation to Big Data computing, but its results are even more extraordinary when paired with Alluxio. Alluxio, provides Spark with a reliable data sharing layer, enabling Spark to excel at performing application logic while Alluxio handles storage. Bazaarvoice uses the combination of Spark and Alluxio to provide a real time big data platform that has the ability to not only handle the intake of 1.5 billion page views during peak events like Black Friday, but also provide real time analytics against it (read more). At this scale, the gain in speed is an enabler for new workloads. We’ve established a clean and simple way to integrate Alluxio and Spark.

Announcing Alluxio 2.0 Preview – enabling hyper-scale data workloads in the cloud

We are thrilled and excited to announce the availability of Alluxio 2.0 Preview Release – the largest open source release with the most new features and improvements since the creation of the project. It is now available for download.
While Alluxio already enabled data locality and data accessibility for many big data workloads in the cloud, there was still innovation needed in key areas.

Top 5 Performance Tuning Tips for Presto caching using Alluxio

Presto is an open source distributed SQL engine widely recognized for its low-latency queries, high concurrency, and native ability to query multiple data sources. Alluxio is an open-source distributed file system that provides a unified data access layer at in-memory speed. The combination of Presto and Alluxio is getting more popular in many companies like JD, NetEase to leverage Alluxio as distributed caching tier on top of slow or remote storage for the hot data to query, avoiding reading data repeatedly from the cloud. In general, Presto doesn’t include a distributed caching tier and Alluxio enables caching of files and objects that the Presto query engine needs.
