As the amount of data being collected and analyzed by Enterprises continues to grow unabated, more attention is being placed on managing the cost of storing the data relative to performance. Hadoop provides a scalable and fast way of storing and analyzing data, however, the cost of storing data in Hadoop is typically higher compared to alternative technologies like Object Stores.

One of the major values Alluxio provides is a simple and unified interface to manage files and directories on different underlying storage systems. Alluxio acts as an intermediate layer and exposes a file interface for applications to interact with, even though the underlying storage system might be an object store that has a different interface. This blog describes our experience in speeding up Alluxio metadata operations using fingerprint and Alluxio under store bulk operations. These latest optimizations can be found in the 1.8.1 release.

Welcome Eric Whitlow from our friends at Starburst Data...
With more companies using Presto for reporting and analytics, we here at Starburst are seeing more use cases around operational reporting. These types of queries need to be returned subsecond and usually involve a small subset of the dataset.
Presto was designed from the ground up to offer interactive analytics using a massively parallel processing SQL engine that can combine data from multiple sources using a variety of connectors. As more and more companies discover the power of “separation of storage and compute” along with querying the data where it lies, it’s not wonder Presto is being asked to add even more functionality.

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.

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.

The hadoop ecosystem makes many distributed system/algorithms easier to use and generally lowers the cost of operations. However, enterprises and vendors are never satisfied with that, so higher performance becomes the next issue. We considered several options to address our performance needs and focused our efforts on Alluxio, which improves performance with intelligent caching.

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.

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.

The primary appeal of a coupled compute-storage architecture, an architecture where the computation is happening on the machines where the data resides, is the performance possible by bringing the compute engine to the data it requires; however, the costs of maintaining such tight-knit architectures are gradually overtaking the performance benefits. Especially with the popularity of cloud resources, being able to independently scale compute and storage results in large cost savings and cheaper maintenance. This post explores the benefits Alluxio brings in these environments...

Processing and storing data in the cloud, such as Amazon S3, Microsoft Azure Blob Storage, or Google Cloud Storage is a growing trend. The global availability and cost effectiveness of these public cloud storage services make them the preferred storage for data. However, running data processing pipelines while sharing data via cloud storage can be expensive in terms of increased network traffic, and slower data sharing and job completion times. Recently, organizations have been deploying Alluxio to support various cloud-based pipelines, to improve performance and reduce costs.

Deep learning algorithms have traditionally been used in specific applications, most notably, computer vision, machine translation, text mining, and fraud detection. Deep learning truly shines when the model is big and trained on large-scale datasets. Meanwhile, distributed computing platforms like Spark are designed to handle big data and have been used extensively. Therefore, by having deep learning available on Spark, the application of deep learning is much broader, and now businesses can fully take advantage of deep learning capabilities using their existing Spark infrastructure.
