If one disk fails on a given Alluxio worker, the Alluxio client on the application side will detect from either the failure or a timeout, then the client will check other workers serving the same data block since one block may have multiple replicas cached in Alluxio space and go to other workers to continue … Continued

This Alluxio Meetup features a chance to interact with other Alluxio users and developers, as well as three talks. Thanks to our joint host Data Council!
How do we access AWS S3 data when running Presto in an on-premise environment, how can we do it efficiently to reduce both egress cost and performance runtimes? Alluxio as a local cache for Presto queries against remote AWS S3 data sources As we move toward more and more decoupled environments one of the things … Continued
Increasingly S3 is being used as a data store for analytical and machine learning workloads. This means that it is very easy to generate a massive amount of get operations and request data from S3. For example: a couple of commands can launch a 1000 node cluster of AWS EMR service with the Spark or … Continued
Introducing S3 and Spark S3 has become the de-facto standard API for digital business applications to store unstructured data chunks. To this end, several vendors have S3-API compatible offerings that allow app developers to standardize on the S3 API’s on-premise, and port these apps to run on other platforms when ready. So, what is S3 and … Continued
TensorFlow is an open source machine learning platform used to build applications like deep neural networks. It consists of an ecosystem of tools, libraries, and community resources for machine learning, artificial intelligence and data science applications. S3 is an object storage service that was created originally by Amazon. It has a rich set of API’s … Continued
This technical salon will focus on big data, storage, database and Alluxio application practice, and invite Tencent technical experts and industry technical experts to share the basic principles of Alluxio system, big data system architecture, database application operation and maintenance, AI computer. Themes such as visual technology and landing practice bring rich practical content and experience exchange.
Alluxio has run in JD.com’s production environment on 100 nodes for six months. Mao Baolong, Yiran Wu, and Yupeng Fu explain how JD.com uses Alluxio to provide support for ad hoc and real-time stream computing, using Alluxio-compatible HDFS URLs and Alluxio as a pluggable optimization component. To give just one example, one framework, JDPresto, has seen a 10x performance improvement on average. This work has also extended Alluxio and enhanced the syncing between Alluxio and HDFS for consistency.
Join us for our first monthly office hour. This month we will focus on:
Installing Alluxio using Docker and Homebrew on your local Linux/Mac machine and accessing data from S3 and HDFS, Understanding Alluxio’s architecture in the data ecosystem, Open Session for discussion on any topics such as solving the separation of compute and storage problem, unifying multiple storage systems, and more.
