ALLUXIO COMMUNITY OFFICE HOUR
Users deploy Alluxio in a wide range of use cases from analytics to AI platforms, for Alluxio’s unified access to data and transparent caching for acceleration. However, many frameworks are SQL engines, like Presto, Apache Spark SQL, or Apache Hive, and consume data structured as tables of rows and columns. Since Alluxio is commonly used as a filesystem of files and directories, there is a mismatch between how Alluxio exposes data (files, directories), and how SQL engines deal with data (tables, rows, columns). This gap creates various challenges and inefficiencies.
Therefore, in the Alluxio 2.1 release, we introduce Alluxio Structured Data Management, which is a new set of services that enables structured data applications to interact with data more efficiently. The new services include the catalog service and a transformation service, which all work together to bridge the gap between storage and SQL engines and enable physical data independence.
In this office hour, we introduce the concepts and components of Alluxio Structured Data Management, and go through a demo with Presto.
In this Office Hour we’ll go over:
- Introduction and motivation of Alluxio Structured Data Management
- Overview of the different services of Alluxio Structured Data Management in Alluxio 2.1
- A demo of using Alluxio Structured Data Management with Presto

Real-time OLAP databases are optimized for speed and often rely on tightly coupled storage-compute architectures using disks or SSDs. Decoupled architectures, which use cloud object storage, introduce an unavoidable tradeoff: cost efficiency at the expense of performance. This makes them unsuitable for databases that need to provide low-latency, real-time analytics, especially the new wave of LLM-powered dashboards, retrieval-augmented generation (RAG), and vector-embedding searches that thrive only when fresh data is milliseconds away. Can we achieve both cost efficiency and performance?
In this talk, we’ll explore the engineering challenges of extending Apache Pinot—a real-time OLAP system—onto cloud object storage while still maintaining sub-second P99 latencies.
We’ll dive into how we built an abstraction in Apache Pinot to make it agnostic to the location of data. We’ll explain how we can query data directly from the cloud (without needing to download the entire dataset, as with lazy-loading) while achieving sub-second latencies. We’ll cover the data fetch and optimization strategies we implemented, such as pipelining fetch and compute, prefetching, selective block fetches, index pinning, and more. We'll also share our latest work about integration with open table formats like iceberg, and how we will continue to achieve fast analytics directly on parquet files by implementing all the same techniques that apply to tiered storage.
