We are excited to present Alluxio 2.0 to our community. The goal of Alluxio 2.0 was to significantly enhance data accessibility with improved APIs, expand use cases supported to include active workloads as well as better metadata management and availability to support hyperscale deployments. Alluxio 2.0 Preview Release is the first major milestone on this path to Alluxio 2.0 and includes many new features.
In this talk, I will give an overview of the motivations and design decisions behind the major changes in the Alluxio 2.0 release. We will touch on the key features:
– New off-Heap metadata storage leveraging embedded RocksDB to scale up Alluxio to handle a billion files;
– Improved Alluxio POSIX API to support legacy and machine-learning workloads;
– A fully contained, distributed embedded journal system based on RAFT consensus algorithm in high availability mode;
– A lightweight distributed compute framework called “Alluxio Job Service” to support Alluxio operations such as active replication, async-persist, cross mount move/copy and distributed loading;
– Support for mounting and connecting to any number of HDFS clusters of different versions at the same time;
Active file system sync between Alluxio and HDFS as under storage.

Real-time Data Processing for Sales Attribution Analysis with Alluxio, Spark and Hive at VIPShop
Vipshop is a leading eCommerce company in China with over 15 million active daily users. Our ETL jobs primarily run against data on HDFS, which can no longer meet the increasing swiftness and stability demand for certain real-time jobs. In this talk, I will explain how we’ve replaced HDFS with Memory+ HDD managed by Alluxio to speed up data accesses for all our Sales Attribution applications running on Spark and Hive, this system has been in production for more than 2 years. As more old fashion ETL SQLs are being converted into real-time jobs, leveraging Alluxio for caching has become one of the widely considered performance tuning solution. I will share our criteria when selecting use cases that can effectively get a boost by switching to Alluxio.
Our future work includes using Alluxio as an abstraction layer for the \tmp\ directory in our main Hadoop clusters, and we are also considering Alluxio to cache the hot data in our 600+ node Presto clusters.

Unlock the full performance of your AI/ML infrastructure on Oracle Cloud Infrastructure (OCI).
Join Oracle's Master Principal Cloud Architect Xinghong He and Alluxio's VP of Technology Bin Fan for an in-depth technical session exploring how modern tiered caching, optimized storage integration, and smart deployment choices can deliver sub-millisecond latency and up to 5× faster data access on OCI — at scale.
You'll learn about:
- Architectural insights: How Alluxio’s tiered caching architecture works with OCI Object Storage and BM.DenseIO compute instances to eliminate data access bottlenecks.
- Benchmark-proven results: See real MLPerf Storage 2.0 and Warp benchmark outcomes demonstrating sub-millisecond latency and dramatic throughput gains.
- Deployment strategies: Compare deployment options — dedicated mode for peak performance vs. co-located mode for cost-efficient scale.
- Practical, actionable guidance: Implementation best practices you can apply directly to your AI/ML workloads on OCI.
Fireworks AI is a leading inference cloud provider for Generative AI, powering real-time inference and fine-tuning services for customers' applications that require minimal latency, high throughput, and high concurrency. Their GPU infrastructure spans 10+ clouds and 15+ regions, serving enterprises and developers deploying production AI workloads at scale.
With model sizes reaching 70GB+, Fireworks AI faced critical challenges: eliminating cold start delays, managing highly concurrent model downloads across GPU clusters, reducing tens of thousands in annual cloud egress costs, and automating manual pipeline management that consumed 4+ hours weekly. They chose Alluxio as their solution to scale with their hyper-growth without requiring dedicated infrastructure resources.
In this tech talk, Akram Bawayah, Software Engineer at Fireworks AI, and Bin Fan, VP of Technology at Alluxio, share how Fireworks AI uses Alluxio to power their multi-cloud inference infrastructure.
They discuss:
- How Fireworks AI uses Alluxio in its high-performance model distribution system to deliver fast, reliable inference across multiple clouds
- How implementing Alluxio distributed caching achieved 1TB/s+ model deployment throughput, reducing model loading from hours to minutes while significantly cutting cloud egress costs
- How to simplify infrastructure operations and seamlessly scale model distribution across multi-cloud GPU environments
