Hive 0.14 adds ACID transactional support which allows for inserting, updating, and deleting rows in Hive tables. It uses a new transaction manager and lock manager to provide snapshot isolation across DML statements. Data is stored in HDFS in a layout of base files and transactional delta files which are compacted periodically. This allows Hive to support use cases beyond batch loads such as streaming data ingest and updating dimension tables.
The document discusses new features in Hive 2.0 including Hive LLAP (Live Long And Process) and Hive on ACID (Atomic, Consistent, Isolated, Durable). Hive LLAP introduces an in-memory caching mechanism that provides sub-second query performance for Hive. Hive on ACID allows for transactions on Hive tables including updates, deletes, and streaming ingestion while maintaining consistency and concurrency. The document provides overviews of how both features work and improvements they provide for analytics workloads on Hive.

Hive & HBase for Transaction Processing Hadoop Summit EU Apr 2015alanfgates
The document discusses using Hive, HBase, Phoenix, and Calcite to build a single data store for both analytics and transaction processing. It describes some recent improvements to Hive like LLAP (Live Long and Process) that aim to achieve sub-second query response times, as well as using HBase as the Hive metastore to improve performance.
The document discusses Hive's new ACID (atomicity, consistency, isolation, durability) functionality which allows for updating and deleting rows in Hive tables. Key points include Hive now supporting SQL commands like INSERT, UPDATE and DELETE; storing changes in delta files and using transaction IDs; and running minor and major compactions to consolidate delta files. Future work may include multi-statement transactions, updating/deleting in streaming ingest, Parquet support, and adding MERGE statements.
- Hive originally only supported updating partitions by overwriting entire files, which caused issues for concurrent readers and limited functionality like row-level updates.
- The need for ACID transactions in Hive arose from wanting to support updating data in near real-time as it arrives and making ad hoc data changes without complex workarounds.
- Hive's ACID implementation stores changes as delta files, uses the metastore to manage transactions and locks, and runs compactions to merge deltas into base files.
- There were initial issues around correctness, performance, usability and resilience, but many have been addressed with ongoing work focused on further improvements and new features like multi-statement transactions and better integration with LLAP.
How to use Hadoop for operational and transactional purposes by RODRIGO MERI...Big Data Spain
Hadoop is an open source framework designed to rapidly ingest, store, and analyze large data sets. Hadoop is well suited for batch processing where immediate interactive analytics are not required. But today, Hadoop does not support the operational and transactional workloads. These workloads consist of a constant flow of transactions requiring low-latency response times for read/write access.

ORC files were originally introduced in Hive, but have now migrated to an independent Apache project. This has sped up the development of ORC and simplified integrating ORC into other projects, such as Hadoop, Spark, Presto, and Nifi. There are also many new tools that are built on top of ORC, such as Hive’s ACID transactions and LLAP, which provides incredibly fast reads for your hot data. LLAP also provides strong security guarantees that allow each user to only see the rows and columns that they have permission for.
This talk will discuss the details of the ORC and Parquet formats and what the relevant tradeoffs are. In particular, it will discuss how to format your data and the options to use to maximize your read performance. In particular, we’ll discuss when and how to use ORC’s schema evolution, bloom filters, and predicate push down. It will also show you how to use the tools to translate ORC files into human-readable formats, such as JSON, and display the rich metadata from the file including the type in the file and min, max, and count for each column.

Apache Phoenix Query Server PhoenixCon2016Josh Elser
This document discusses Apache Phoenix Query Server, which provides a client-server abstraction for Apache Phoenix using Apache Calcite's Avatica sub-project. It allows Phoenix to have thin clients by offloading computational resources to query servers running on Hadoop clusters. This enables non-Java clients through a standardized HTTP API. The query server implementation uses HTTP, Protocol Buffers for serialization, and common libraries like Jetty and Dropwizard Metrics. It aims to simplify Phoenix client development and improve performance and scalability.
Apache Phoenix’s relational database view over Apache HBase delivers a powerful tool which enables users and developers to quickly and efficiently access their data using SQL. However, Phoenix only provides a Java client, in the form of a JDBC driver, which limits Phoenix access to JVM-based applications. The Phoenix QueryServer is a standalone service which provides the building blocks to use Phoenix from any language, not just those running in a JVM. This talk will serve as a general purpose introduction to the Phoenix QueryServer and how it complements existing Apache Phoenix applications. Topics covered will range from design and architecture of the technology to deployment strategies of the QueryServer in production environments. We will also include explorations of the new use cases enabled by this technology like integrations with non-JVM based languages (Ruby, Python or .NET) and the high-level abstractions made possible by these basic language integrations.
Apache Hive is a rapidly evolving project which continues to enjoy great adoption in the big data ecosystem. As Hive continues to grow its support for analytics, reporting, and interactive query, the community is hard at work in improving it along with many different dimensions and use cases. This talk will provide an overview of the latest and greatest features and optimizations which have landed in the project over the last year. Materialized views, the extension of ACID semantics to non-ORC data, and workload management are some noteworthy new features.
We will discuss optimizations which provide major performance gains, including significantly improved performance for ACID tables. The talk will also provide a glimpse of what is expected to come in the near future.
This document discusses new features in Apache Hive 2.0, including:

Transactional operations in Apache Hive: present and futureDataWorks Summit
Apache Hive is an enterprise data warehouse build on top of Hadoop. Hive supports insert, update, delete, and merge SQL operations with transactional semantics and read operations that run at snapshot isolation. The well defined semantics of these operations in the face of failure and concurrency are critical to building robust application on top of Apache Hive. In the past there were many preconditions to enabling these features which meant giving up other functionality. The need to make these tradeoffs is rapidly being eliminated.
This talk will describe the intended use cases, architecture of the implementation, recent improvements and new features build for Hive 3.0. For example, bucketing transactional tables, while supported, is no longer required. Performance overhead of using transactional tables is nearly eliminated relative to identical non-transactional tables. We’ll also cover Streaming Ingest API, which allows writing batches of events into a Hive table without using SQL.

As Apache Solr becomes more powerful and easier to use, the accessibility of high quality data becomes key to unlocking the full potential of Solr’s search and analytic capabilities. Traditional approaches to acquiring data frequently involve a combination of homegrown tools and scripts, often requiring significant development efforts and becoming hard to change, hard to monitor, and hard to maintain. This talk will discuss how Apache NiFi addresses the above challenges and can be used to build production-grade data pipelines for Solr. We will start by giving an introduction to the core features of NiFi, such as visual command & control, dynamic prioritization, back-pressure, and provenance. We will then look at NiFi’s processors for integrating with Solr, covering topics such as ingesting and extracting data, interacting with secure Solr instances, and performance tuning. We will conclude by building a live dataflow from scratch, demonstrating how to prepare data and ingest to Solr.

Achieving Real-time Ingestion and Analysis of Security Events through Kafka a...Kevin Mao
Strata Hadoop World 2017 San Jose
Today’s enterprise architectures are often composed of a myriad of heterogeneous devices. Bring-your-own-device policies, vendor diversification, and the transition to the cloud all contribute to a sprawling infrastructure, the complexity and scale of which can only be addressed by using modern distributed data processing systems.
Kevin Mao outlines the system that Capital One has built to collect, clean, and analyze the security-related events occurring within its digital infrastructure. Raw data from each component is collected and preprocessed using Apache NiFi flows. This raw data is then written into an Apache Kafka cluster, which serves as the primary communications backbone of the platform. The raw data is parsed, cleaned, and enriched in real time via Apache Metron and Apache Storm and ingested into ElasticSearch, allowing operations teams to detect and monitor events as they occur. The refined data is also transformed into the Apache ORC data format and stored in Amazon S3, allowing data scientists to perform long-term, batch-based analysis.
Kevin discusses the challenges involved with architecting and implementing this system, such as data quality, performance tuning, and the impact of additional financial regulations relating to data governance, and shares the results of these efforts and the value that the data platform brings to Capital One.

RISELab: Enabling Intelligent Real-Time Decisions keynote by Ion StoicaSpark Summit
A long-standing grand challenge in computing is to enable machines to act autonomously and intelligently: to rapidly and repeatedly take appropriate actions based on information in the world around them. To address this challenge, at UC Berkeley we are starting a new five year effort that focuses on the development of data-intensive systems that provide Real-Time Intelligence with Secure Execution (RISE). Following in the footsteps of AMPLab, RISELab is an interdisciplinary effort bringing together researchers across AI, robotics, security, and data systems. In this talk I’ll present our research vision and then discuss some of the applications that will be enabled by RISE technologies.
New Directions in pySpark for Time Series Analysis: Spark Summit East talk by...Spark Summit
The document provides an overview of using PySpark for time series analysis. It discusses that time series data can come from sources like IOT feeds, sensor data, and economic indicators. Time series analysis in PySpark allows for windowed aggregations and temporal joins on massive time series datasets that can be both wide and narrow. While basic analytics are possible in PySpark, libraries like Flint provide additional functions specialized for time series analysis on large datasets in a distributed environment. The document encourages attendees to speak with the author after the talk to see a time series analysis library in PySpark demonstrated.
Trends for Big Data and Apache Spark in 2017 by Matei ZahariaSpark Summit
Big data remains a rapidly evolving field with new applications and infrastructure appearing every year. In this talk, I’ll cover new trends in 2016 / 2017 and how Apache Spark is moving to meet them.

Hive 3 new SQL features including LLAP, workload management, SQL over Kafka and JDBC data sources, integration with Spark via Hive Warehouse Connector, ACID 2, and constraints and default values
Apache Hive is a rapidly evolving project which continues to enjoy great adoption in the big data ecosystem. As Hive continues to grow its support for analytics, reporting, and interactive query, the community is hard at work in improving it along with many different dimensions and use cases. This talk will provide an overview of the latest and greatest features and optimizations which have landed in the project over the last year. Materialized views, the extension of ACID semantics to non-ORC data, and workload management are some noteworthy new features.
We will discuss optimizations which provide major performance gains, including significantly improved performance for ACID tables. The talk will also provide a glimpse of what is expected to come in the near future.
Speaker: Alan Gates, Co-Founder, Hortonworks
This document discusses the new features of Apache Hive 2.0, including:
1) The addition of procedural SQL capabilities through HPLSQL to add features like cursors and loops.
2) Performance improvements for interactive queries through LLAP which uses in-memory caching and persistent daemons.
3) Using HBase as the metastore to speed up query planning by reducing metadata access times.
4) Enhancements to Hive on Spark such as dynamic partition pruning and vectorized joins.
5) Improvements to the cost-based optimizer including better statistics collection.
Apache Hive 2.0 provides major new features for SQL on Hadoop such as:
- HPLSQL which adds procedural SQL capabilities like loops and branches.
- LLAP which enables sub-second queries through persistent daemons and in-memory caching.
- Using HBase as the metastore which speeds up query planning times for queries involving thousands of partitions.
- Improvements to Hive on Spark and the cost-based optimizer.
- Many bug fixes and under-the-hood improvements were also made while maintaining backwards compatibility where possible.
This document summarizes Hortonworks' Data Cloud, which allows users to launch and manage Hadoop clusters on cloud platforms like AWS for different workloads. It discusses the architecture, which uses services like Cloudbreak to deploy HDP clusters and stores data in scalable storage like S3 and metadata in databases. It also covers improving enterprise capabilities around storage, governance, reliability, and fault tolerance when running Hadoop on cloud infrastructure.
Hadoop & cloud storage object store integration in production (final)Chris Nauroth
Today's typical Apache Hadoop deployments use HDFS for persistent, fault-tolerant storage of big data files. However, recent emerging architectural patterns increasingly rely on cloud object storage such as S3, Azure Blob Store, GCS, which are designed for cost-efficiency, scalability and geographic distribution. Hadoop supports pluggable file system implementations to enable integration with these systems for use cases such as off-site backup or even complex multi-step ETL, but applications may encounter unique challenges related to eventual consistency, performance and differences in semantics compared to HDFS. This session explores those challenges and presents recent work to address them in a comprehensive effort spanning multiple Hadoop ecosystem components, including the Object Store FileSystem connector, Hive, Tez and ORC. Our goal is to improve correctness, performance, security and operations for users that choose to integrate Hadoop with Cloud Storage. We use S3 and S3A connector as case study.
This document discusses Hadoop integration with cloud storage. It describes the Hadoop-compatible file system architecture, which allows Hadoop applications to work with both HDFS and cloud storage transparently. Recent enhancements to the S3A file system connector for Amazon S3 are discussed, including performance improvements and support for encryption. Benchmark results show significant performance gains for Hive queries with S3A compared to earlier versions. Upcoming work on output committers, object store abstraction, and consistency are outlined.

Dancing Elephants - Efficiently Working with Object Stores from Apache Spark ...DataWorks Summit
This document discusses challenges and solutions for using object storage with Apache Spark and Hive. It covers:
- Eventual consistency issues in object storage and lack of atomic operations
- Improving performance of object storage connectors through caching, optimized metadata operations, and consistency guarantees
- Techniques like S3Guard and committers that address consistency and correctness problems with output commits in object storage
LLAP (Live Long and Process) is the newest query acceleration engine for Hive 2.0, which entered GA in 2017. LLAP brings into light a new set of trade-offs and optimizations that allows for efficient and secure multi-user BI systems on the cloud. In this talk, we discuss the specifics of building a modern BI engine within those boundaries, designed to be fast and cost-effective on the public cloud. The focus of the LLAP cache is to speed up common BI query patterns on the cloud, while avoiding most of the operational administration overheads of maintaining a caching layer, with an automatically coherent cache with intelligent eviction and support for custom file formats from text to ORC, and explore the possibilities of combining the cache with a transactional storage layer which supports online UPDATE and DELETES without full data reloads. LLAP by itself, as a relational data layer, extends the same caching and security advantages to any other data processing framework. We overview the structure of such a hybrid system, where both Hive and Spark use LLAP to provide SQL query acceleration on the cloud with new, improved concurrent query support and production-ready tools and UI.

Cloudy with a chance of Hadoop - real world considerationsDataWorks Summit
Over the last eighteen months, we have seen significant adoption of Hadoop eco-system centric big data processing in Microsoft Azure and Amazon AWS. In this talk we present some of the lessons learned and architectural considerations for cloud-based deployments including security, fault tolerance and auto-scaling.
We look at how Hortonworks Data Cloud and Cloudbreak can automate that scaling of Hadoop clusters, showing how it can react dynamically to workloads, and what that can deliver in cost-effective Hadoop-in-cloud deployments.
The document discusses strategies for storing time series data from IoT devices in Apache HBase. It describes how IoT data streams typically have a time-series format with identifiers, timestamps and values. It proposes using HBase to store the raw, compressed and aggregated time series data separately with different retention policies. FIFO compaction is recommended for raw data while ECPM or date tiered compaction could be used for compressed and aggregated data. This would reduce read and write I/O compared to the default HBase settings while preserving the temporal locality of the time series data.
Apache Hadoop 3.0 is coming! As the next major release, it attracts everyone's attention as show case several bleeding-edge technologies and significant features across all components of Apache Hadoop, include: Erasure Coding in HDFS, Multiple Standby NameNodes, YARN Timeline Service v2, JNI-based shuffle in MapReduce, Apache Slider integration and Service Support as First Class Citizen, Hadoop library updates and client-side class path isolation, etc.
In this talk, we will update the status of Hadoop 3 especially the releasing work in community and then go deep diving on new features included in Hadoop 3.0. As a new major release, Hadoop 3 would also include some incompatible changes - we will go through most of these changes and explore its impact to existing Hadoop users and operators. In the last part of this session, we will continue to discuss ongoing efforts in Hadoop 3 age and show the big picture that how big data landscape could be largely influenced by Hadoop 3.
Adding ACID Transactions, Inserts, Updates, and Deletes in Apache HiveDataWorks Summit
This document summarizes Hortonworks' work to add ACID transaction support to Apache Hive. It describes how Hive will store data in buckets with transaction IDs to allow for inserts, updates and deletes while maintaining snapshot isolation for reads. Minor and major compactions will merge delta files to improve performance. The initial release in Hive 0.13 will focus on transactions and compactions, with future releases adding SQL commands and additional isolation levels. ACID support will make Hive more suitable for interactive analytics and ETL workloads.
Sanjay Radia presents on evolving HDFS to support a generalized storage subsystem. HDFS currently scales well to large clusters and storage sizes but faces challenges with small files and blocks. The solution is to (1) only keep part of the namespace in memory to scale beyond memory limits and (2) use block containers of 2-16GB to reduce block metadata and improve scaling. This will generalize the storage layer to support containers for multiple use cases beyond HDFS blocks.
Dancing elephants - efficiently working with object stores from Apache Spark ...DataWorks Summit
As Hadoop applications move into cloud deployments, object stores become more and more the source and destination of data. But object stores are not filesystems: sometimes they are slower; security is different,
What are the secret settings to get maximum performance from queries against data living in cloud object stores? That's at the filesystem client, the file format and the query engine layers? It's even how you lay out the files —the directory structure and the names you give them.
We know these things, from our work in all these layers, from the benchmarking we've done —and the support calls we get when people have problems. And now: we'll show you.
This talk will start from the ground up "why isn't an object store a filesystem?" issue, showing how that breaks fundamental assumptions in code, and so causes performance issues which you don't get when working with HDFS. We'll look at the ways to get Apache Hive and Spark to work better, looking at optimizations which have been done to enable this —and what work is ongoing. Finally, we'll consider what your own code needs to do in order to adapt to cloud execution.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
