Two Ways to Keep Files in Sync Between Alluxio and HDFS

David Zhu Apr 16th, 2019

Alluxio provides a distributed data access layer for applications like Spark or Presto to access different underlying file system (or UFS) through a single API in a unified file system namespace. If users only interact with the files in the UFS through Alluxio, since Alluxio has knowledge of any changes the client makes to the UFS, it will keep Alluxio namespace in sync with the UFS namespace (see the left figure below). However, where a file in the UFS is changed without going through Alluxio, the UFS namespace and the Alluxio namespace can potentially get out of sync. When this happens, a UFS Metadata Sync operation is required to synchronize the two namespaces (illustrated in the right figure).

Moving From Apache Thrift to gRPC: A Perspective From Alluxio

Bin Feng Gokturk Gezer Apr 13th, 2019

Thrift served well as a fast and reliable RPC framework powering the metadata operations in Alluxio 1.x. Its limitation in handling streamed data has led us to a journey in search of better alternatives. gRPC provides some nice features that help us in building a simpler, more unified API layer. In this post, we discussed some lessons learned to move from Thrift to gRPC, including performance tuning tips that helped us achieve comparable performance for both one-off RPC calls as well as data streams.

China Unicom Uses Alluxio and Spark to Build New Computing Platform to Serve Mobile Users

Zhang Ce Apr 10th, 2019

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. The complicated the architecture of its incumbent computing platform created a lot of new challenges to effectively use resources. Fortunately there is a new generation of distributed computation frameworks that can help China Unicom meet the enormous data challenges for a variety of business scenarios. To solve these problems, the company built a new software stack of Apache Spark, Alluxio, HDFS, Hive and Apache Kafka. They used Alluxio as the core component for a unified, memory-centric distributed data processing platform with consolidated resources, and improved computation efficiency.

Store 1 Billion Files in Alluxio 2.0

Andrew Audibert Apr 9th, 2019

Alluxio 2.0 is designed to support 1 billion files in a single file system namespace. Namespace scaling is vital to Alluxio for a couple of reasons: 1. Alluxio provides a single namespace where multiple storage systems can be mounted. So the size of Alluxio's namespace is the sum of the sizes of all mounted storages. 2. Object storage is increasing in popularity, and object stores often hold many more small files compared with filesystems like HDFS.

Data Location Awareness: Optimize Performance and Lower Cost with Tiered Locality

Andrew Audibert Jul 24th, 2018

Caching frequently used data in memory is not a new computing technique, however it is a concept that Alluxio has taken to the next level with the ability to aggregate data from multiple storage systems in a unified pool of memory. Alluxio capabilities extend further to intelligently managing the data within that virtual data layer. Tiered locality uses awareness of network topology and configurable policies to manage data placement for performance and cost optimizations. This feature is particularly useful with cloud deployments across multiple availability zones. It can also be useful for cost savings in environments where cross-zone or cross-location traffic is more expensive than intra-zone data traffic.

Asynchronous Caching in Alluxio - High Performance for Partial Read Caching

Calvin Jia Jul 10th, 2018

An Alluxio cluster caches data from connected storage systems in memory to create a data layer that can be accessed concurrently by multiple application frameworks. This greatly improves performance for many analytics workloads. On-demand caching occurs when clients read blocks of data using a ‘CACHE’ read type from persistent storage systems connected to the Alluxio cluster. Prior to Alluxio v1.7, on-demand caching was on the critical path of read operations, requiring a full block to be read before the data was available for the application. Workloads which read partial blocks, for example SQL workloads, would be adversely affected on initial reads from connected storage. For example, when reading the footer of a parquet file, the client only requests a small amount of data, but the client reads the entire data block in order to cache it.

Neena Pemmaraju Mar 12th, 2018

Lenovo is an Alluxio customer with a common problem and use case in the world of data analytics. They have petabytes of data in multiple data centers in different geographic locations. Analyzing it requires an ETL process to get all of the data in the right place. This is both slow, because data has to be transferred across the network, and costly because multiple copies of the data need to be stored. Freshness and quality of the data can also suffer as the data is also potentially out of date and incomplete because regulatory issues prevent certain data from being transferred.

New Whitepaper: Structured Big Data Federation

Gene Pang Feb 28th, 2018

Enterprises are adopting big data technologies to analyze and derive insight from their growing volumes of structured and unstructured data. A familiar problem is the requirement to analyze data from multiple independent storage silos concurrently. In order to consolidate the data, large enterprises typically use custom solutions or build a data lake. These approaches present additional challenges and can be costly and time consuming. Alluxio helps organizations handle their big data by providing a unified view of all of the data in your enterprise – on premise, in the cloud, or hybrid. Applications access data using a standard interface to a global virtual namespace. Alluxio also employs a memory-centric architecture to enable data access at memory speed. With the combined unification and performance benefits, Alluxio can effectively provide big data federation for organizations by acting as a virtual data lake. We just published a whitepaper that goes into further detail, you can access it here: Structured Big Data Federation Using Alluxio.
