EOD Session
Lars Hofhansl HBase Futures

Speaker: Sudarshan Kadambi and Matthew Hunt (Bloomberg LP) Bloomberg is a financial data and analytics provider, so data management is core to what we do. There's tremendous diversity in the type of data we manage, and HBase is a natural fit for many of these datasets - from the perspective of the data model as well as in terms of a scalable, distributed database. This talk covers data and analytics use cases at Bloomberg and operational challenges around HA. We'll explore the work currently being done under HBASE-10070, further extensions to it, and how this solution is qualitatively different to how failover is handled by Apache Cassandra.

Harmonizing Multi-tenant HBase Clusters for Managing Workload Diversity

HBaseCon

Speakers: Dheeraj Kapur, Rajiv Chittajallu & Anish Mathew (Yahoo!) In early 2013, Yahoo! introduced multi-tenancy to HBase to offer it as a platform service for all Hadoop users. A certain degree of customization per tenant (a user or a project) was achieved through RegionServer groups, namespaces, and customized configs for each tenant. This talk covers how to accommodate diverse needs to individual tenants on the cluster, as well as operational tips and techniques that allow Yahoo! to automate the management of multi-tenant clusters at petabyte scale without errors.

Cloudera, Inc.

Speakers: Nick Dimiduk (Hortonworks) and Nicolas Liochon (Scaled Risk) HBase is an online database so response latency is critical. This talk will examine sources of latency in HBase, detailing steps along the read and write paths. We'll examine the entire request lifecycle, from client to server and back again. We'll also look at the different factors that impact latency, including GC, cache misses, and system failures. Finally, the talk will highlight some of the work done in 0.96+ to improve the reliability of HBase.

HBase: Extreme Makeover

HBaseCon

Speaker: Vladimir Rodionov (bigbase.org) This talks introduces a totally new implementation of a multilayer caching in HBase called BigBase. BigBase has a big advantage over HBase 0.94/0.96 because of an ability to utilize all available server RAM in the most efficient way, and because of a novel implementation of a L3 level cache on fast SSDs. The talk will show that different type of caches in BigBase work best for different type of workloads, and that a combination of these caches (L1/L2/L3) increases the overall performance of HBase by a very wide margin.

Cloudera, Inc.

This session is a case study of how we used our already existing HBase cluster as content addressable storage for BLOBs. We will discuss how we wrote a CAS implementation using HBase as the backend, Scala and Finagle as the application and using caching reverse proxies (i.e. Varnish in our case) for serving BLOBs at scale. The talk will dicuss why content addressable storage is the right pattern for many web use cases, how to foster an already existing HBase cluster for better usage of possibly underutilized resources, and operational gotchas to store and serve BLOBs from HBase at scale.

HBaseCon 2012 | HBase and HDFS: Past, Present, Future - Todd Lipcon, Cloudera

Cloudera, Inc.

Apache HDFS, the file system on which HBase is most commonly deployed, was originally designed for high-latency high-throughput batch analytic systems like MapReduce. Over the past two to three years, the rising popularity of HBase has driven many enhancements in HDFS to improve its suitability for real-time systems, including durability support for write-ahead logs, high availability, and improved low-latency performance. This talk will give a brief history of some of the enhancements from Hadoop 0.20.2 through 0.23.0, discuss some of the most exciting work currently under way, and explore some of the future enhancements we expect to develop in the coming years. We will include both high-level overviews of the new features as well as practical tips and benchmark results from real deployments.

HBase Read High Availability Using Timeline-Consistent Region Replicas

HBaseCon

Speakers: Enis Soztutar and Devaraj Das (Hortonworks) HBase has ACID semantics within a row that make it a perfect candidate for a lot of real-time serving workloads. However, single homing a region to a server implies some periods of unavailability for the regions after a server crash. Although the mean time to recovery has improved a lot recently, for some use cases, it is still preferable to do possibly stale reads while the region is recovering. In this talk, you will get an overview of our design and implementation of region replicas in HBase, which provide timeline-consistent reads even when the primary region is unavailable or busy.

HBaseCon 2012 | HBase, the Use Case in eBay Cassini

Cloudera, Inc.

eBay marketplace has been working hard on the next generation search infrastructure and software system, code-named Cassini. The new search engine processes over 250 million search queries and serves more than 2 billion page views each day. Its indexing platform is based on Apache Hadoop and Apache HBase. Apache HBase is a distributed persistent layer built on Hadoop to support billions of updates per day. Its easy sharding character, fast writes, and table scans, super fast data bulk load, and natural integration to Hadoop provide the cornerstones for successful continuous index builds. We will share with the audience the technical details and share the difficulties and challenges that we’ve gone through and that we are still facing in the process.

HBaseCon 2012 | Base Metrics: What They Mean to You - Cloudera

Cloudera, Inc.

If you’re running an HBase cluster in production, you’ve probably noticed that HBase shares a number of useful metrics about everything from your block cache performance to your HDFS latencies over JMX (or Ganglia, or just a file). The problem is that it’s sometimes hard to know what these metrics mean to you and your users. Should you be worried if your memstore SizeMB is 1.5GB? What if your regionservers have a hundred stores each? This talk will explain how to understand and interpret the metrics HBase exports. Along the way we’ll cover some high-level background on HBase’s internals, and share some battle tested rules-of-thumb about how to interpret and react to metrics you might see.

Keynote: Apache HBase at Yahoo! Scale

HBaseCon

Yahoo has long been involved in HBase and its community. In 2013, HBase was offered as a hosted service at Yahoo. Since then, adoption has grown rapidly., and today, HBase is used by numerous teams across the company, helping to enable a diverse set of use cases ranging from near real-time processing to data warehousing. This was made possible thanks to HBase along with some enhancements to support multi-tenancy and scale. As our clusters continue to grow and use cases become more demanding we are working towards supporting a million regions in a single cluster. In this keynote, we’ll paint a picture of where Yahoo! is today and the enhancements we have been working on to reach today’s scale as well as supporting a million regions and beyond.

Embedded Recipes 2019 - Overview of Fuchsia, a new operating system

Anne Nicolas

Fuchsia is a radically new open-source operating system actively developed by Google since 2016. Its first targets are supposed to be IoT devices but multiple form-factors, including laptops, are already supported. It may be challenging to grasp what is really new or interesting in this OS, and from different points of view (system developer, user app developer, security enthusiast or end user). The purpose of this talk is to highlight and explain some interesting features and architecture choices, what is similar or different from other mainstream operating systems, what can we expect from Fuchsia, along with some insights on the development (from an outside point of view).

How to Choose a Software Update Mechanism for Embedded Linux Devices

Leon Anavi

How to Choose a Software Update Mechanism for Embedded Linux Devices by Leon Anavi, Konsulko Group Embedded Linux Conference NA 2022 and Open Source Summit NA 2022 Atomic software system update of an embedded Linux device has always been an important part of any product, especially nowadays with the existing large fleets of connected devices and Internet of Things. There are several different widely used in the industry approaches: A/B updates with dual redundant scheme, delta updates, container-based updates and combined strategies. Open source technologies such as Mender, RAUC and libostree based solutions implement these strategies and provide tools to manage updates of multiple devices. What are the advantages and disadvantages? How to choose an appropriate open source solution for a specific project? This session explores a number of different open source Linux software update technologies with practical examples for integrating them using the Yocto Project and OpenEmbedded. In order to better understand the strengths and weaknesses of each technology, we deep dive in various use cases. The talk is appropriate for anyone with basic knowledge about Linux. It will hopefully help managers, engineers and developers better understand the technical challenges and the available open source solutions with which to overcome them easier and faster so that they can focus on the unique core features of their products.

hbaseconasia2017: HareQL：快速HBase查詢工具的發展過程

HBaseCon

Mon-Fong Mike Jiang, Kuan-Yu Hubert Fan-Chiang and Tienyu Rebecca Lin 自2011年起，我們就開始使用HBase作為結構化大數據的儲存工具，主要是做為半導體製造設備參數的分析。為了有效進行數據查詢，我們開發Standard Query Language(SQL)的整合介面，最早的方式是(1)自行開發GUI操作介面及(2)透過自行定義SQL語法的方式進行，但是這樣會衍生出很多額外的工作，特別是SQL Parser與對應的HBase API的連結。為了解決此問題，我們解析了Hive QL Parser作為主要的核心，將此部分的原始碼整合進HareDB HBase Client之中，另外，也整合了HBase Coprocessor，可以加速查詢的進行，這個架構我們實際使用在數個半導體製造廠的大數據系統中，也展現了高查詢效率。除此之外，透過整合Kafka來處理串流數據的匯入，同時對於數據分析的呈現也加上Cube建立工具，這些都是實際開發大數據系統時陸續面對的問題與解決方法，我們將分享這一連串的系統開發過程。 hbaseconasia2017 hbasecon hbase https://www.eventbrite.com/e/hbasecon-asia-2017-tickets-34935546159#

hbaseconasia2017: Large scale data near-line loading method and architecture

HBaseCon

Shuaifeng Zhou When we do real-time data loading to HBase, we use put/putlist interface. After receiving put request, regionserver will write WAL, write data into memory store, flush memory store to disk-store, then compact files again and again. That precedure occupies too much resource and causing read/write performance decrease. To solve the problem, we provide a kind of near-line loading method and architecture, greatly increase the loading bandwidth, and decrease the influence to read operations. hbaseconasia2017 hbasecon hbase https://www.eventbrite.com/e/hbasecon-asia-2017-tickets-34935546159#

HBaseCon2017 Democratizing HBase

HBaseCon

As HBase and Hadoop continue to become routine across enterprises, these enterprises inevitably shift priorities from effective deployments to cost-efficient operations. Consolidation of infrastructure, the sum of hardware, software, and system-administrator effort, is the most common strategy to reduce costs. As a company grows, the number of business organizations, development teams, and individuals accessing HBase grows commensurately, creating a not-so-simple requirement: HBase must effectively service many users, each with a variety of use-cases. This is problem is known as multi-tenancy. While multi-tenancy isn’t a new problem, it also isn’t a solved one, in HBase or otherwise. This talk will present a high-level view of the common issues organizations face when multiple users and teams share a single HBase instance and how certain HBase features were designed specifically to mitigate the issues created by the sharing of finite resources.

HBaseCon

HBase is used to serve online facing traffic in Pinterest. It means no downtime is allowed. However, we were on HBase 94. To upgrade to latest version, we need to figure out a way to live upgrade while keeping Pinterest site live. Recently, we successfully upgrade 94 HBase cluster to 1.2 with no downtime. We made change to both Asynchbase and HBase server side. We will talk about what we did and how we did it. We will also talk about the finding in config and performance tuning we did to achieve low latency.

HBaseCon2017 Quanta: Quora's hierarchical counting system on HBase

HBaseCon

Hundreds of millions of people use Quora to find accurate, informative, and trustworthy answers to their questions. As it so happens, counting things at scale is both an important and a difficult problem to solve. In this talk, we will be talking about Quanta, Quora's counting system built on top of HBase that powers our high-volume near-realtime analytics that serves many applications like ads, content views, and many dashboards. In addition to regular counting, Quanta supports count propagation along the edges of an arbitrary DAG. HBase is the underlying data store for both the counting data and the graph data. We will describe the high-level architecture of Quanta and share our design goals, constraints, and choices that enabled us to build Quanta very quickly on top of our existing infrastructure systems.

HBaseCon2017 Transactions in HBase

HBaseCon

In the age of NoSQL, big data storage engines such as HBase have given up ACID semantics of traditional relational databases, in exchange for high scalability and availability. However, it turns out that in practice, many applications require consistency guarantees to protect data from concurrent modification in a massively parallel environment. In the past few years, several transaction engines have been proposed as add-ons to HBase; three different engines, namely Omid, Tephra, and Trafodion were open-sourced in Apache alone. In this talk, we will introduce and compare the different approaches from various perspectives including scalability, efficiency, operability and portability, and make recommendations pertaining to different use cases.

In DiDi Chuxing Company, which is China’s most popular ride-sharing company. we use HBase to serve when we have a bigdata problem. We run three clusters which serve different business needs. We backported the Region Grouping feature back to our internal HBase version so we could isolate the different use cases. We built the Didi HBase Service platform which is popular amongst engineers at our company. It includes a workflow and project management function as well as a user monitoring view. Internally we recommend users use Phoenix to simplify access.even more,we used row timestamp;multidimensional table schema to slove muti dimension query problems C++, Go, Python, and PHP clients get to HBase via thrift2 proxies and QueryServer. We run many important buisness applications out of our HBase cluster such as ETA/GPS/History Order/API metrics monitoring/ and Traffic in the Cloud. If you are interested in any aspects listed above, please come to our talk. We would like to share our experiences with you.

How to Position Your Globus Data Portal for Success Ten Good Practices

Globus

Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

First Steps with Globus Compute Multi-User Endpoints

Globus

In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...

Globus

The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
