It’s 2017, and big data challenges are as real as they get. Our customers have petabytes of data living in elastic and scalable commodity storage systems such as Azure Data Lake Store and Azure Blob storage. One of the central questions today is finding insights from data in these storage systems in an interactive manner, at a fraction of the cost. Interactive Query leverages [Hive on LLAP] in Apache Hive 2.1, brings the interactivity to your complex data warehouse style queries on large datasets stored on commodity cloud storage. In this session, you will learn how technologies such as Low Latency Analytical Processing [LLAP] and Hive 2.x are making it possible to analyze petabytes of data with sub second latency with common file formats such as csv, json etc. without converting to columnar file formats like ORC/Parquet. We will go deep into LLAP’s performance and architecture benefits and how it compares with Spark and Presto in Azure HDInsight. We also look at how business analysts can use familiar tools such as Microsoft Excel and Power BI, and do interactive query over their data lake without moving data outside the data lake. Speaker Ashish Thapliyal, Principal Program Manager, Microsoft Corp

Xiaomi is a Chinese technology company, it sells more than 100 million smartphones worldwide in 2018, and also owns one of the world's largest IoT device platforms. Xiaomi builds dozens of mobile apps and Internet services based on intelligent devices, including Ads, news feeds, finance service, game, music, video, personal cloud service and so on. The rapid growth of business results in exponential growth of the data analytics infrastructure. The amount of data has roared more than 20 times in the past 3 years, which renders us big challenges on the HDFS scalability In this talk, we introduce how we scale HDFS to support hundreds of PB data with thousands nodes: 1. How Xiaomi use Hadoop and the characteristic of our usage 2. We made HDFS federation cluster to be used like a single cluster, most applications don't need to change any code to migrate from a single cluster to a federation cluster. Our works include a wrapper FileSystem compatible with DistributedFileSystem, supporting rename among different name spaces and zookeeper-based mount table renewer. 3. Experience of tuning NameNode to improve scalability 4. How to maintain hundreds of HDFS clusters and the optimization we did on client-side to make user and programs access these clusters easily with high performance

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.

When interacting with analytics dashboards, in order to achieve a smooth user experience, two major key requirements are quick response time and data freshness. To meet the requirements of creating fast interactive BI dashboards over streaming data, organizations often struggle with selecting a proper serving layer. Cluster computing frameworks such as Hadoop or Spark work well for storing large volumes of data, although they are not optimized for making it available for queries in real time. Long query latencies also make these systems suboptimal choices for powering interactive dashboards and BI use cases. This talk presents an open source real time data analytics stack using Apache Kafka, Druid, and Superset. The stack combines the low-latency streaming and processing capabilities of Kafka with Druid, which enables immediate exploration and provides low-latency queries over the ingested data streams. Superset provides the visualization and dashboarding that integrates nicely with Druid. In this talk we will discuss why this architecture is well suited to interactive applications over streaming data, present an end-to-end demo of complete stack, discuss its key features, and discuss performance characteristics from real-world use cases.

Time series data is everywhere: IoT, sensor data, financial transactions. The industry has moved to databases like Cassandra to handle the high velocity and high volume of data that is now common place. However data is pointless without being able to process it in near real time. That's where Spark combined with Cassandra comes in! What was one just your storage system (Cassandra) can be transformed into an analytics system and it's really surprising how easy it is!

At the StampedeCon 2015 Big Data Conference: This talk will examine the benefits of using multiple persistence strategies to build an end-to-end predictive engine. Utilizing Spark Streaming backed by a Cassandra persistence layer allows rapid lookups and inserts to be made in order to perform real-time model scoring. Spark backed by Parquet files, stored in HDFS, allows for high-throughput model training and tuning utilizing Spark MLlib. Both of these persistence layers also provide ad-hoc queries via Spark SQL in order to easily analyze model sensitivity and accuracy. Storing the data in this way also provides extensibility to leverage existing tools like CQL to perform operational queries on the data stored in Cassandra and Impala to perform larger analytical queries on the data stored in HDFS further maximizing the benefits of the flexible architecture.

One of the most popular use cases for Apache Druid is building data applications. Data applications exist to deliver data into the hands of everyone on a team in a business, and are used by these teams to make faster, better decisions. To fulfill this role, they need to support granular drill down, because the devil is in the details, but also be extremely fast, because otherwise people won't use them! In this talk, Gian Merlino will cover: *The unique technical challenges of powering data-driven applications *What attributes of Druid make it a good platform for data applications *Some real-world data applications powered by Druid

The information age has allowed everyone to tap into the exponential production of data. Unfortunately, much actionable insight is the result of unexpected or anomalous behavior that can only be recognized through experience. A collection of NLP microservices was crafted to complement an organization’s existing technology infrastructure in order to translate and bring additional meaning to an organization’s already existing and real time collection of unstructured text. In this session, and in collaboration with Partners & Co., a Chicago-based real estate firm, we will demonstrate how we can leverage an organization’s collective knowledge and turn unstructured text that is generated from across various communication mediums into real time actionable insight. We will demonstrate how we can use a combination of open source tools such as Apache NiFi, Kafka, OpenNLP, and Superset to build a full streaming NLP pipeline to consume unstructured text, detect the language and sentences within the text, deconstruct the grammatical makeup, and derive meaning of the entities identified within the text.

Druid is a high performance, column-oriented distributed data store that is widely used at Oath for big data analysis. Druid has a JSON schema as its query language, making it difficult for new users unfamiliar with the schema to start querying Druid quickly. The JSON schema is designed to work with the data ingestion methods of Druid, so it can provide high performance features such as data aggregations in JSON, but many are unable to utilize such features, because they not familiar with the specifics of how to optimize Druid queries. However, most new Druid users at Yahoo are already very familiar with SQL, and the queries they want to write for Druid can be converted to concise SQL. We found that our data analysts wanted an easy way to issue ad-hoc Druid queries and view the results in a BI tool in a way that's presentable to nontechnical stakeholders. In order to achieve this, we had to bridge the gap between Druid, SQL, and our BI tools such as Apache Superset. In this talk, we will explore different ways to query a Druid datasource in SQL and discuss which methods were most appropriate for our use cases. We will also discuss our open source contributions so others can utilize our work. GURUGANESH KOTTA, Software Dev Eng, Oath and JUNXIAN WU, Software Engineer, Oath Inc.

Companies are increasingly moving to the cloud to store and process data. In this talk, we will talk through how companies can use tag-based policies in Apache Ranger to protect access to data both in on-premises environments as well in AWS-based cloud environments. We will go into details of how tag-based policies work and the integration with Apache Atlas and various services. We will also talk through how companies can leverage Ranger’s policies to anonymize or tokenize data while moving into the cloud and de-anonymize dynamically using Apache Kafka, Apache Hive, Apache Spark, or plain old ETL using MapReduce. We will also deep dive into Ranger’s proposed integration with S3 and other cloud-native systems. We will wrap it up with an end-to-end demo showing how tags and tag-based masking policies can be used to anonymize sensitive data and track how tags are propagated within the system and how sensitive data can be protected using tag-based policies Speakers Don Bosco Durai, Chief Security Architect, Privacera Madhan Neethiraj, Sr. Director of Engineering, Hortonworks

"The data coming into Kafka is fresh and hot. And you can deliver a new level of operational visibility and intelligence fueling applications with it. But streaming data is no longer real-time when the sink is batch. So the challenge is processing it and analyzing it at scale and extracting those insights - before they go stale. So what’s the right architecture? Should you ingest streams into a data warehouse or data lake? Maybe use a stream processor or a database? Engineering teams love using Apache Flink, but they also love using Apache Druid, a popular real-time analytics database used by 1000s of companies like Confluent and Netflix. Do you need Flink and Druid? When does it make sense vs when does it not? Join this session to learn about Apache Druid and why companies use it in combination with Kafka and Flink for real-time applications. Learn how Apache Druid complements Flink and Kafka - and what makes it purpose-built for analyzing streams and events. This talk shows real-world examples from companies that use Apache Druid with Kafka and Flink in production today and the best-practices that every dev can take advantage of."

Yilin Xia (yilinx2@illinois.edu), Shawn Bowers (bowers@gonzaga.edu), Lan Li (lanl2@illinois.edu), and Bertram Ludäscher (ludaesch@illinois.edu) Presented at IDCC-2024 in Edinburg. ABSTRACT. We propose a new approach for modeling and reconciling conflicting data cleaning actions. Such conflicts arise naturally in collaborative data curation settings where multiple experts work independently and then aim to put their efforts together to improve and accelerate data cleaning. The key idea of our approach is to model conflicting updates as a formal argumentation framework (AF). Such argumentation frameworks can be automatically analyzed and solved by translating them to a logic program PAF whose declarative semantics yield a transparent solution with many desirable properties, e.g., uncontroversial updates are accepted, unjustified ones are rejected, and the remaining ambiguities are exposed and presented to users for further analysis. After motivating the problem, we introduce our approach and illustrate it with a detailed running example introducing both well-founded and stable semantics to help understand the AF solutions. We have begun to develop open source tools and Jupyter notebooks that demonstrate the practicality of our approach. In future work we plan to develop a toolkit for conflict resolution that can be used in conjunction with OpenRefine, a popular interactive data cleaning tool.
