Flink Forward Berlin 2018: Stefan Richter - "Tuning Flink for Robustness and ...Flink Forward

Flink's stateful stream processing engine presents a huge variety of optional features and configuration choices to the user. Figuring out the ""optimal"" choices for any production environment and use-case can therefore often be challenging. In this talk, we will explore and discuss the universe of Flink configuration with respect to robustness and performance. We will start with a closer look under the hood, at core data structures and algorithms, to build the foundation for understanding the impact of tuning parameters and the costs-benefit-tradeoffs that come with certain features and options. In particular, we will focus on state backend choices (Heap vs RocksDB), tuning checkpointing (incremental checkpoints, ...) and recovery (local recovery), file systems, TTL state, and considerations for the network stack. This also includes a discussion about estimating memory requirements and memory partitioning.

View, Act, and React: Shaping Business Activity with Analytics, BigData Queri...Srinath Perera

Sun Tzu said “if you know your enemies and know yourself, you can win a hundred battles without a single loss.” Those words have never been truer than in our time. We are faced with an avalanche of data. Many believe the ability to process and gain insights from a vast array of available data will be the primary competitive advantage for organizations in the years to come. To make sense of data, you will have to face many challenges: how to collect, how to store, how to process, and how to react fast. Although you can build these systems from bottom up, it is a significant problem. There are many technologies, both open source and proprietary, that you can put together to build your analytics solution, which will likely save you effort and provide a better solution. In this session, Srinath will discuss WSO2’s middleware offering in BigData and explain how you can put them together to build a solution that will make sense of your data. The session will cover technologies like thrift for collecting data, Cassandra for storing data, Hadoop for analyzing data in batch mode, and Complex event processing for analyzing data real time.

Some of the specific topics covered are: * Overview of RDS and EC2 – pros, cons and usage patterns/antipatterns. * Implementation choices in both offerings: instance sizing, ephemeral SSDs, EBS, provisioned IOPS and advanced techniques (RAID, mixed storage environments, etc…) * Leveraging regions and availability zones for availability, business continuity and disaster recovery. * Scaling patterns including read/write splitting, read distribution, functional dataset partitioning and horizontal dataset partitioning (aka sharding) * Common failure modes – AZ and Region failures, EBS corruption, EBS performance inconsistencies and more. * Managing and mitigating cost with various instance and storage options

Storage essentials (by Merlin Ran)gigix1980

The document discusses storage area network (SAN) concepts and technologies. It describes how SANs increase storage utilization by consolidating storage and eliminating "islands" of dedicated storage. SANs provide higher availability than direct-attached storage by enabling features like backups without downtime and faster disaster recovery. The document outlines SAN protocols like Fibre Channel and iSCSI, as well as RAID levels and their characteristics. It also discusses business continuity strategies and how different replication technologies impact recovery point and recovery time objectives.

RDS for MySQL, No BS Operations and PatternsLaine Campbell

RDS for MySQL provides a fully managed MySQL database in the cloud. It handles backups, provisioning, patching, and failover automatically. While convenient, RDS has some limitations like inability to choose database versions, limited control over maintenance windows, and downtime required for migrations or upgrades. Careful planning is needed for workloads with high availability or latency requirements. Overall RDS reduces DBA overhead but still requires expertise for design, tuning, and automation.

This document provides an overview of high availability and disaster recovery strategies for Azure SQL solutions. It discusses recovery time and point objectives and available options like Always On availability groups and failover cluster instances. It also covers backup and restore, factors to consider in a HADR strategy, and differences between infrastructure as a service and platform as a service solutions. Specific options covered include availability sets, availability zones, log shipping, Azure Site Recovery, temporal tables, active geo-replication, and auto failover groups.

Aerospike ArchitecturePeter Milne

The document provides an overview of the Aerospike architecture, including the client, cluster, storage, indexes, RAM, flash storage, and cross datacenter replication (XDR). It describes Aerospike's goals of handling high transaction volumes at low latency while scaling linearly. The key aspects of the architecture are the smart client that routes to data in one hop, shared-nothing nodes, single row transactions, smart cluster management, and XDR for data replication across datacenters.

How analogue intelligence complements AIPaul Rowe

Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results. News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?
