Big Data Day LA 2015 - Introducing N1QL: SQL for Documents by Jeff Morris of ...Data Con LA
NoSQL has exploded on the developer scene promising alternatives to RDBMS that make rapidly developing, Internet scale applications easier than ever. However, as a trade off to the ease of development and scale, some of the familiarity with other well-known query interfaces such as SQL, has been lost. Until now that is...N1QL (pronounced ‘N1QL’) is a SQL like query language for querying JSON, which brings the familiarity of RDBMS back to the NoSQL world. In this session you will learn about the syntax and basics of this new language as well as Integration with the Couchbase SDKs.
A New “Sparkitecture” for Modernizing your Data Warehouse: Spark Summit East ...Spark Summit
Legacy enterprise data warehouse (EDW) architecture, geared toward day-to-day workloads associated with operational querying, reporting, and analytics, are often ill-equipped to handle the volume of data, traffic, and varied data types associated with a modern, ad-hoc analytics platform. Faced with challenges of increasing pipeline speed, aggregation, and visualization in a simplified, self-service fashion, organizations are increasingly turning to some combination of Spark, Hadoop, Kafka, and proven analytical databases like Vertica as key enabling technologies to optimize their EDW architecture. Join us to learn how successful organizations have developed real-time streaming solutions with these technologies for range of use cases, including IOT predictive maintenance.
Apache Flink is a popular stream computing framework for real-time stream computing. Many stream compute algorithms require trailing data in order to compute the intended result. One example is computing the number of user logins in the last 7 days. This creates a dilemma where the results of the stream program are incomplete until the runtime of the program exceeds 7 days. The alternative is to bootstrap the program using historic data to seed the state before shifting to use real-time data.
This talk will discuss alternatives to bootstrap programs in Flink. Some alternatives rely on technologies exogenous to the stream program, such as enhancements to the pub/sub layer, that are more generally applicable to other stream compute engines. Other alternatives include enhancements to Flink source implementations. Lyft is exploring another alternative using orchestration of multiple Flink programs. The talk will cover why Lyft pursued this alternative and future directions to further enhance bootstrapping support in Flink.

A Day in the Life of a Druid Implementor and Druid's RoadmapItai Yaffe
Benjamin Hopp (Solutions Architect) @ Imply:
Druid is an emerging standard in the data infrastructure world, designed for high-performance slice-and-dice analytics (“OLAP”-style) on large data sets.
This talk is for you if you’re interested in learning more about pushing Druid’s analytical performance to the limit.
Perhaps you’re already running Druid and are looking to speed up your deployment, or perhaps you aren’t familiar with Druid and are interested in learning the basics.
Some of the tips in this talk are Druid-specific, but many of them will apply to any operational analytics technology stack.
The most important contributor to a fast analytical setup is getting the data model right.
The talk will center around various choices you can make to prepare your data to get best possible query performance.
We’ll look at some general best practices to model your data before ingestion such as OLAP dimensional modeling (called “roll-up” in Druid), data partitioning, and tips for choosing column types and indexes.
We’ll also look at how more can be less: often, storing copies of your data partitioned, sorted, or aggregated in different ways can speed up queries by reducing the amount of computation needed.
We’ll also look at Druid-specific optimizations that take advantage of approximations; where you can trade accuracy for performance and reduced storage.
You’ll get introduced to Druid’s features for approximate counting, set operations, ranking, quantiles, and more.
And we will finish with the latest and greatest Druid news, including details about the latest roadmap and releases.
Stream All Things—Patterns of Modern Data Integration with Gwen ShapiraDatabricks
Data integration is a really difficult problem. We know this because 80% of the time in every project is spent getting the data you want the way you want it. We know this because this problem remains challenging despite 40 years of attempts to solve it. All we want is a service that will be reliable, handle all kinds of data and integrate with all kinds of systems, be easy to manage and scale as our systems grow. Oh, and it should be super low latency too. Is it too much to ask?
In this presentation, we’ll discuss the basic challenges of data integration and introduce few design and architecture patterns that are used to tackle these challenges. We will then explore how these patterns can be implemented using Apache Kafka. Difficult problems are difficult and we offer no silver bullets, but we will share pragmatic solutions that helped many organizations build fast, scalable and manageable data pipelines.

Presto is an open source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes. Presto was designed and written from the ground up for interactive analytics and approaches the speed of commercial data warehouses while scaling to the size of organizations like Facebook. One key feature in Presto is the ability to query data where it lives via a uniform ANSI SQL interface. Presto’s connector architecture creates an abstraction layer for anything that can be expressed in a row-like format, such as HDFS, Amazon S3, Azure Storage, NoSQL stores, relational databases, Kafka streams and even proprietary data stores. Furthermore, a single Presto query can combine data from multiple sources, allowing for analytics across your entire organization.
This talk will be co-presented by Facebook and Teradata, the two largest contributors to Presto. The talk will focus on Presto’s ability to query virtually any data source via it’s connector interface. Facebook and Teradata will present some of their use cases of Presto querying various data sources, discuss the existing connectors in Presto, and describe the anatomy of a connector.

Tl;dr; How to make Apache Spark process data efficiently? Lessons learned from running petabyte scale Hadoop cluster and dozens of spark jobs’ optimisations including the most spectacular: from 2500 gigs of RAM to 240.
Apache Spark is extremely popular for processing data on Hadoop clusters. If Your Spark executors go down, an amount of memory is increased. If processing goes too slow, number of executors is increased. Well, this works for some time but sooner or later You end up with a whole cluster fully utilized in an inefficient way.
During the presentation, we will present our lessons learned and performance improvements on Spark jobs including the most spectacular: from 2500 gigs of RAM to 240. We will also answer the questions like:
- How does pySpark job differ from Scala jobs in terms of performance?
- How does caching affect dynamic resource allocation
- Why is it worth to use mapPartitions?
and many more.

Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware.
It provides massive storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs. The core of Apache Hadoop consists of a storage part (HDFS) and a processing part (MapReduce).
This presentation is about apache hadoop technology. This may be helpful for the beginners. The beginners will know about some terminologies of hadoop technology. There is also some diagrams which will show the working of this technology.
Thank you.

Apache Kudu (Incubating): New Hadoop Storage for Fast Analytics on Fast Data ...Cloudera, Inc.
The Hadoop ecosystem has improved real-time access capabilities recently, narrowing the gap with relational database technologies. However, gaps remain in the storage layer that complicate the transition to Hadoop-based architectures. In this session, the presenter will describe these gaps and discuss the tradeoffs between real-time transactional access and fast analytic performance from the perspective of storage engine internals. The session also will cover Kudu (currently in beta), the new addition to the open source Hadoop ecosystem with outof-the-box integration with Apache Spark and Apache Impala (incubating), that achieves fast scans and fast random access from a single API.
Hadoop is emerging as the preferred solution for big data analytics across unstructured data. Using real world examples learn how to achieve a competitive advantage by finding effective ways of analyzing new sources of unstructured and machine-generated data.
You’ve successfully deployed Hadoop, but are you taking advantage of all of Hadoop’s features to operate a stable and effective cluster? In the first part of the talk, we will cover issues that have been seen over the last two years on hundreds of production clusters with detailed breakdown covering the number of occurrences, severity, and root cause. We will cover best practices and many new tools and features in Hadoop added over the last year to help system administrators monitor, diagnose and address such incidents.
The second part of our talk discusses new features for making daily operations easier. This includes features such as ACLs for simplified permission control, snapshots for data protection and more. We will also cover tuning configuration and features that improve cluster utilization, such as short-circuit reads and datanode caching.
Are you taking advantage of all of Hadoop’s features to operate a stable and effective cluster? Inspired by real-world support cases, this talk discusses best practices and new features to help improve incident response and daily operations. Chances are that you’ll walk away from this talk with some new ideas to implement in your own clusters.
The current major release, Hadoop 2.0 offers several significant HDFS improvements including new append-pipeline, federation, wire compatibility, NameNode HA, Snapshots, and performance improvements. We describe how to take advantages of these new features and their benefits. We cover some architectural improvements in detail such as HA, Federation and Snapshots. The second half of the talk describes the current features that are under development for the next HDFS release. This includes much needed data management features such as backup and Disaster Recovery. We add support for different classes of storage devices such as SSDs and open interfaces such as NFS; together these extend HDFS as a more general storage system. Hadoop has recently been extended to run first-class on Windows which expands its enterprise reach and allows integration with the rich tool-set available on Windows. As with every release we will continue improvements to performance, diagnosability and manageability of HDFS. To conclude, we discuss the reliability, the state of HDFS adoption, and some of the misconceptions and myths about HDFS.
Some of the most common questions we hear from users relate to capacity planning and hardware choices. How many replicas do I need? Should I consider sharding right away? How much RAM will I need for my working set? SSD or HDD? No one likes spending a lot of cash on hardware and cloud bills can just be as painful. MongoDB is different from traditional RDBMSs in its resource management, so you need to be mindful when deciding on the cluster layout and hardware. In this talk we will review the factors that drive the capacity requirements: volume of queries, access patterns, indexing, working set size, among others. Attendees will gain additional insight as we go through a few real-world scenarios, as experienced with MongoDB Inc customers, and come up with their ideal cluster layout and hardware.
In this session, we'll discuss architectural, design and tuning best practices for building rock solid and scalable Alfresco Solutions. We'll cover the typical use cases for highly scalable Alfresco solutions, like massive injection and high concurrency, also introducing 3.3 and 3.4 Transfer / Replication services for building complex high availability enterprise architectures.

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.
Large Language Models and the End of ProgrammingMatt Welsh

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
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.

We’ll look at specific Apache JIRA issues, some not yet shipped, some still in progress. Small patches often yield big wins. Sometimes those patches are even small enough to fit on a PowerPoint slide, as you’re about to see. Some are larger.
These are common challenges for any large Java codebase, not just specific to Hadoop.
Too little logging. Size of code change: 3 characters. Without this extra logging information, diagnosis is very challenging.
Too much logging.
Kerberos is notorious for obtuse error messages that don’t directly point out root cause.
These are often steps we need to follow in any case that requires Kerberos troubleshooting. Codifying these steps into a standard tool makes gathering this information easier and more consistent.
Helps find the naughty user who is overwhelming your cluster.
“smoothing”
In contrast to managing an overloaded situation, how can we more effectively handle more load?
Garbage collection friendly data structures are particularly relevant to the NameNode, which has a large heap size requirement.
Data structure not efficient for duplicate entries. (Not the use case.)
We’ve talked about how HDFS can better react to overloaded conditions, and we’ve talked about improving HDFS to handle more total load. What is the source of that load? Is it legitimate?
I encourage you to explore and analyze the HDFS audit log in your clusters.
Improving the API to encourage more efficient applications.
Performance of HDFS itself and also optimizing applications.
