Understanding blue store, Ceph's new storage backend - Tim Serong, SUSEOpenStack
Audience Level
Intermediate
Synopsis
Ceph – the most popular storage solution for OpenStack – stores all data as a collection of objects. This object store was originally implemented on top of a POSIX filesystem, an approach that turned out to have a number of problems, notably with performance and complexity.
BlueStore, a new storage backend for Ceph, was created to solve these issues; the Ceph Jewel release included an early prototype. The code and on-disk format were declared stable (but experimental) for Ceph Kraken, and now in the upcoming Ceph Luminous release, BlueStore will be the recommended default storage backend.
With a 2-3x performance boost, you’ll want to look at migrating your Ceph clusters to BlueStore. This talk goes into detail about what BlueStore does, the problems it solves, and what you need to do to use it.
Speaker Bio:
Tim works for SUSE, hacking on Ceph and related technologies. He has spoken often about distributed storage and high availability at conferences such as linux.conf.au. In his spare time he wrangles pigs, chickens, sheep and ducks, and was declared by one colleague “teammate most likely to survive the zombie apocalypse”.

Performance Tuning RocksDB for Kafka Streams' State Stores (Dhruba Borthakur,...confluent
RocksDB is the default state store for Kafka Streams. In this talk, we will discuss how to improve single node performance of the state store by tuning RocksDB and how to efficiently identify issues in the setup. We start with a short description of the RocksDB architecture. We discuss how Kafka Streams restores the state stores from Kafka by leveraging RocksDB features for bulk loading of data. We give examples of hand-tuning the RocksDB state stores based on Kafka Streams metrics and RocksDB’s metrics. At the end, we dive into a few RocksDB command line utilities that allow you to debug your setup and dump data from a state store. We illustrate the usage of the utilities with a few real-life use cases. The key takeaway from the session is the ability to understand the internal details of the default state store in Kafka Streams so that engineers can fine-tune their performance for different varieties of workloads and operate the state stores in a more robust manner.
Meta/Facebook's database serving social workloads is running on top of MyRocks (MySQL on RocksDB). This means our performance and reliability depends a lot on RocksDB. Not just MyRocks, but also we have other important systems running on top of RocksDB. We have learned many lessons from operating and debugging RocksDB at scale.
In this session, we will offer an overview of RocksDB, key differences from InnoDB, and share a few interesting lessons learned from production.
Amazon DynamoDB Under the Hood: How We Built a Hyper-Scale Database (DAT321) ...Amazon Web Services
Come to this session to learn how Amazon DynamoDB was built as the hyper-scale database for internet-scale applications. In January 2012, Amazon launched DynamoDB, a cloud-based NoSQL database service designed from the ground up to support extreme scale, with the security, availability, performance, and manageability needed to run mission-critical workloads. This session discloses for the first time the underpinnings of DynamoDB, and how we run a fully managed nonrelational database used by more than 100,000 customers. We cover the underlying technical aspects of how an application works with DynamoDB for authentication, metadata, storage nodes, streams, backup, and global replication.
AWS Glue는 고객이 분석을 위해 손쉽게 데이터를 준비하고 로드할 수 있게 지원하는 완전관리형 ETL(추출, 변환 및 로드) 서비스입니다. AWS 관리 콘솔에서 클릭 몇 번으로 ETL 작업을 생성하고 실행할 수 있습니다. 빅데이터 분석 시 다양한 데이터 소스에 대한 전처리 작업을 할 때, 별도의 데이터 처리용 서버나 인프라를 관리할 필요가 없습니다. 본 세션에서는 지난 5월 서울 리전에 출시한 Glue 서비스에 대한 자세한 소개와 함께 다양한 활용 팁을 데모와 함께 소개해 드립니다.
최근 국내와 글로벌 서비스에서 MongoDB를 사용하는 사례가 급증하고 있습니다. 다만 전통적인 RDBMS에 비해, 아직 지식과 경험의 축적이 적게 되어 있어 손쉬운 접근과 트러블 슈팅등에 문제가 있는 것도 사실입니다. 이 세션에서는 MongoDB 와 AWS의 DocumentDB의 Architecure를 간단히 살펴보고 MongoDB 및 DocumentDB의 비교를 진행하며 특히 MongoDB와 DocumentDB를 사용할때 주의해야할 중요 포인트에 대해서 알아봅니다.

Delta lake is widely adopted. There are things to be aware of when dealing with petabytes of data in Delta Lake. These smart decisions can give the best efficiency and increase the adoption of Delta. Best practices like OPTIMIZE, ZORDER have to wisely chosen. We have support stories where we successfully resolved performance issues by applying the right performance strategy. There are a set of common issues or repeated questions from our strategic customers face when using Delta and in this session we cover them and how to address them.
HBaseCon 2015: Taming GC Pauses for Large Java Heap in HBaseHBaseCon
In this presentation, we will introduce Hotspot's Garbage First collector (G1GC) as the most suitable collector for latency-sensitive applications running with large memory environments. We will first discuss G1GC internal operations and tuning opportunities, and also cover tuning flags that set desired GC pause targets, change adaptive GC thresholds, and adjust GC activities at runtime. We will provide several HBase case studies using Java heaps as large as 100GB that show how to best tune applications to remove unpredicted, protracted GC pauses.
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.
Troubleshooting Kerberos in Hadoop: Taming the BeastDataWorks Summit
Kerberos is the ubiquitous authentication mechanism when it comes to secure any Hadoop Services. With recent updates in Hadoop core and various Apache Hadoop components, inherent Kerberos support has matured and has come a long way.
Understanding & configuring Kerberos is still a challenge but even more painful & frustrating is troubleshooting a Kerberos issue. There are lot of things (small & big) that can go wrong (and will go wrong!). This talk covers the Kerberos debugging part in detail and discusses the tools & tricks that can be used to narrow down any Kerberos issue.
Rather than discussing the issues and their resolution, we will focus on how to approach a Kerberos problem and do's / dont's in Kerberos scene. This talk will provide a step by step guide that will equip the audience for troubleshooting future Kerberos problems.
Agenda is to discuss:
- Systematic approach to Kerberos troubleshooting
- Kerberos Tools available in Hadoop arsenal
- Tips & Tricks to narrow down Kerberos issues quickly
- Some nasty Kerberos issues from Support trenches
Some prior knowledge on Kerberos basics will be appreciated but is not a prerequisite.

Storage tiering and erasure coding in Ceph (SCaLE13x)Sage Weil
Ceph is designed around the assumption that all components of the system (disks, hosts, networks) can fail, and has traditionally leveraged replication to provide data durability and reliability. The CRUSH placement algorithm is used to allow failure domains to be defined across hosts, racks, rows, or datacenters, depending on the deployment scale and requirements.
Recent releases have added support for erasure coding, which can provide much higher data durability and lower storage overheads. However, in practice erasure codes have different performance characteristics than traditional replication and, under some workloads, come at some expense. At the same time, we have introduced a storage tiering infrastructure and cache pools that allow alternate hardware backends (like high-end flash) to be leveraged for active data sets while cold data are transparently migrated to slower backends. The combination of these two features enables a surprisingly broad range of new applications and deployment configurations.
This talk will cover a few Ceph fundamentals, discuss the new tiering and erasure coding features, and then discuss a variety of ways that the new capabilities can be leveraged.
