May 25, 20143 likes1,742 views

This document provides instructions for setting up MongoDB sharding across multiple servers. It describes installing MongoDB on router, config, and shard servers. The config servers store metadata about the cluster, router servers route queries to shards, and data is partitioned across multiple shard servers. The steps shown add a shard to the cluster, check the cluster status, test by sharding a sample database and collection with an indexed key, and suggest adding more shards and data to validate the setup.

MySQL Tokudb engine benchmarkLouis liu

The document compares the performance of MySQL with the InnoDB and TokuDB storage engines on a system with high-performance SSD storage. It finds that InnoDB has better performance than TokuDB for most workloads tested, especially when thread counts increase. However, TokuDB provides much better data compression, nearly halving the storage size compared to InnoDB. For systems with very fast storage, InnoDB's compression is not as beneficial, but its performance is still superior in most tests.

Cassandra Summit 2014: Down with Tweaking! Removing Tunable Complexity for Ca...DataStax Academy

Presenters: Don Marti, Glauber Costa, and Dor Laor of Cloudius Systems The need for performance tuning of the JVM and OS is making administrators the bottleneck for Cassandra deployments--especially in virtual environments. Over the past two years, the OSv project has profiled tuning-sensitive applications with a special focus on Cassandra. Today, many of the important bottlenecks for NoSQL applications are tunable on a conventional OS, but do not require tuning in the OSv environment. OSv gives Cassandra a simpler environment, set up to run one application in a single address space. This talk will cover how to use OSv to improve performance in key areas such as JVM memory allocation and network throughput--without loading up your to-do list with difficult tuning tasks.

Back to Basics: Build Something Big With MongoDB MongoDB

1. Replica sets allow for high availability and redundancy by creating copies of data across multiple nodes. The replica set lifestyle involves creation, initialization, handling failures and failovers, and recovery from failures. 2. When developing with replica sets, developers must consider consistency models such as strong consistency, delayed consistency, and write concerns to determine how and when data is written and acknowledged. Tagging and read preferences also allow control over where data is read from and written to. 3. Sharding provides horizontal scalability by partitioning data across multiple machines or replica sets. The data is split into chunks based on a user-defined shard key and distributed across shards. A config server stores metadata about chunk mappings and locations,

Sharding Methods for MongoDBMongoDB

Sharding in MongoDB allows for horizontal scaling of data and operations across multiple servers. When determining if sharding is needed, factors like available storage, query throughput, and response latency on a single server are considered. The number of shards can be calculated based on total required storage, working memory size, and input/output operations per second across servers. Different types of sharding include range, tag-aware, and hashed sharding. Choosing a high cardinality shard key that matches query patterns is important for performance. Reasons to shard include scaling to large data volumes and query loads, enabling local writes in a globally distributed deployment, and improving backup and restore times.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

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?

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
