In this office hour, we will go over an introduction and motivation of Alluxio Structured Data Management, an overview of the different services in Alluxio 2.1, and a demo using Alluxio Structured Data Management with Presto.
This office hour shares a demo and compares two approaches, caching data directly in-memory into the Spark JVM versus storing data off-heap via an in-memory storage service like Alluxio
In the previous tutorial ”Getting Started with Spark Caching using Alluxio in 5 Minutes”, we demonstrated how to get started with Spark and Alluxio. To share more thoughts and experiments on how Alluxio enhances Spark workloads, this article focuses on how Alluxio helps to optimize the memory utilization of Spark applications. For users who are … Continued
For today’s blog post I interviewed Bin Fan, Founding Engineer and VP of Open Source at Alluxio. Bin is the PMC maintainer of the Alluxio open source project. Prior to Alluxio, he worked for Google on the next-generation storage infrastructure.
In this talk, we present: trends and challenges in the data ecosystem in cloud era; Data engineering in the cloud with data orchestration; Use cases of using tech stacks (Presto or Tensorflow) with Alluxio on S3.
Haoyuan Li offers an overview of a data orchestration layer that provides a unified data access and caching layer for single cloud, hybrid, and multicloud deployments.
Large-scale analytics and AI/ML applications require efficient data access, with data increasingly distributed across multiple data stores in private data centers and clouds. Data platform teams also need the flexibility to introduce new data sources and move to new storage options with minimal changes or downtime for their applications. This paper delves further into what’s driving the need for–and what problems are solved with—an Alluxio data orchestration layer as part of a modern data platform.
I recently worked on a PoC evaluating Nomad for a client. Since there were certain constraints limiting what was possible on the client environment, I put together something “quick” on my personal workstation to see what was required for Alluxio to play nice with Nomad.
Alluxio is a new layer on top of under storage systems that can not only improve raw I/O performance but also enables applications flexible options to read, write and manage files. This article focuses on describing different ways to write files to Alluxio, realizing the tradeoffs in performance, consistency, and also the level of fault tolerance compared to HDFS.
