Brief introduction to MongoDB for people that have never seen it before. Includes links for obtaining more information.

What is MongoDB?
• One of the new breed of non-relational
(“NoSQL”) databases
• A document store
• Instead of flat records (sets of scalars), stores
JSON documents
• Scalars
• Array-valued fields
• Document-valued fields
• Open source

Why MongoDB?
• Availability
• Easy replication
• In principle, similar to MySQL master-slave
• Automated failover
• Failure of the “primary” (current master) is detected,
and a “secondary” (slave) is selected and takes
over automatically

Why MongoDB?
• Scalability
• Easy replication
• Scale reads by permitting reads from secondaries
• Built-in sharding
• Scale writes by spreading load across multiple
shards – each is a replica set
• Shards can be added or removed at will
• No penalty for guessing wrong at start
• System automatically re-balances shards if they
grow disproportionately

Why MongoDB?
• Simplicity
• Simple configuration
• Very few startup parameters
• Flexible document model
• Structured data
• Doesn’t force unnecessary normalization
• Natural-looking language bindings
• Client drivers use native language constructions to
represent documents

MongoDB is not an RDBMS
• Sacrifices made for horizontal scalability
• Eventual Consistency
• Secondaries are not replicas maintained by
distributed transactions
• No transactions
• No joins
• No SQL
• Simpler QBE-style query language

Where does MongoDB Run?
• Designed for commodity hardware
• Can run on O&O infrastructure or in cloud
environments
• Runs on Windows and most flavors of linux
• OSX works, but is not recommended for
production

This document discusses asynchronous programming, Node.js, and isomorphic JavaScript web frameworks. It describes how Node.js uses asynchronous and event-driven programming to handle requests without blocking. It also explains how isomorphic frameworks allow JavaScript code to run on both the client-side and server-side, allowing code reuse and initial page rendering from the server. Traditional frameworks are compared to single page applications and how isomorphic frameworks address some of the challenges with SEO and duplicate code.

Mongo Seattle - The Business of MongoDBJustin Smestad

This document discusses strategies for promoting MongoDB adoption. It recommends understanding MongoDB's features, costs, and use cases before promoting it to potential users. It suggests identifying pain points like complex joins that MongoDB could alleviate for "developers" and performance needs that its MapReduce could address for "managers." Examples of successful MongoDB migrations are presented to convince "skeptics." The goal is to alter perceptions and infect target organizations with MongoDB by solving real problems rather than just touting its features.

MongoDB Strange Loop 2009Mike Dirolf

MongoDB is an open-source, schema-free, document-oriented database that provides high performance, flexibility and scalability. It uses JSON-like documents with dynamic schemas, instead of the traditional table-based relational database structure. MongoDB is especially useful for web applications, caching, and scaling to handle large volumes of data. While it is less suited to highly transactional workloads or problems requiring SQL, MongoDB provides a simple interface and scales horizontally across commodity servers.

Node js Krishna Chaytaniah

Node.js is a JavaScript runtime environment that uses Google Chrome's V8 engine. It allows for high concurrency without threads or processes by using an event loop and callbacks for non-blocking I/O. While it can be used for server-side JavaScript applications, its lack of access to the DOM from the server-side presents some drawbacks compared to traditional client-side JavaScript. Overall, Node.js enables highly scalable applications but its non-blocking nature requires some adjustment for developers accustomed to blocking I/O models.

Stack Exchange Infrastructure - LISA 14GABeech

The Stack Exchange infrastructure supports 560 million page views and 34TB of data transferred per month across 1665 requests per second on average. To ensure high performance, Stack Exchange uses load balancers, web servers, caching, and databases in a redundant configuration. Careful performance monitoring and optimization has resulted in homepage and question page render times of 52ms and 33ms respectively.

MongoDB tuning on AWSRyuji Tamagawa

Ryuji Tamagawa gave a presentation on using MongoDB. He introduced MongoDB as a hybrid of NoSQL and SQL that scales easily. To improve performance on AWS, one must understand MongoDB's memory management, the application's workload pattern, and the size of "hot" data that is frequently accessed. MongoDB does not manage memory itself, instead using memory mapping to leverage the OS buffer. It is important to give the OS enough memory to store hot data and account for indexes. Replication can be used to distribute data across multiple instances for high availability. Performance tests showed SSD-backed instance types had faster write times than non-SSD types for storing Wikipedia data in MongoDB.

This document discusses MongoDB replication, sharding, and aggregation. It explains that replica sets allow for high availability and redundancy through primary-secondary replication across multiple servers. Sharding partitions data by shard key across multiple replica sets to scale databases horizontally. The aggregation framework provides data aggregation capabilities through pipelines of operations like match, project, group, and sort.

Vlad zelinschi optimizing the critical rendering pathCodecamp Romania

The document discusses optimizing the critical rendering path (CRP) of a web page. The CRP refers to the steps between receiving HTML, CSS, and JavaScript and rendering pixels on the screen. These steps include parsing HTML to build the DOM tree, parsing CSS to build the CSSOM tree, combining them into a render tree, running layout to compute geometry, and painting to the screen. Optimizing the CRP means minimizing the time spent in these steps. Some tips include getting CSS to the client fast, eliminating blocking JavaScript from the CRP, and focusing on above-the-fold content. Tools like critical CSS extraction can help optimize the CRP.

Porting ASP.NET applications to Windows AzureGunnar Peipman

Hosting applications on Windows Azure is simple but there are things to change when cloud-enabling existing web applications because cloud is conceptually different than on-premises or shared hosting environment. This sessions goes through main issues one will face when moving applications to cloud. Real-life examples provide elegant solutions to problems and through demos the audience will see how to deploy applications to cloud and how to test and run cloud and hybrid applications on your development machine.

AJAX allows for asynchronous data retrieval and dynamic display. It uses technologies like XML, XSLT, DOM, and JavaScript. Servlet 3.0 includes annotations and methods to support asynchronous processing, allowing requests to be processed asynchronously without blocking the original thread. The AsyncContext class provides an execution context for asynchronous operations and wraps the request and response.

Performance WebRodolfo Fadino Junior

The document discusses factors that affect website performance, including front-end elements like CSS, JavaScript, images, and back-end elements like caching, threading, and database queries. It notes that only 10-20% of response time is spent on downloading HTML, so focus should be on optimizing other parts of the page load. It also outlines the anatomy of an HTTP request and lists 14 rules for improving performance, such as reducing HTTP requests, using content delivery networks, gzipping components, and making AJAX cacheable. It emphasizes that teams should regularly audit performance and prioritize optimizations.

MongoDB's New Aggregation frameworkChris Westin

The document discusses MongoDB's new aggregation framework, which provides a declarative pipeline for performing data aggregation operations on complex documents. The framework allows users to describe a chain of operations without writing JavaScript. It will offer high-performance operators like $match, $project, $unwind, $group, $sort, and computed expressions to reshape and analyze document data without the overhead of JavaScript. The aggregation framework is nearing release and will support sharding by forwarding pipeline operations to shards and combining results.

Replication and replica setsChris Westin

Replication in MongoDB allows for high availability and scaling of reads. A replica set consists of at least three mongod servers, with one primary and one or more secondaries that replicate from the primary. Writes go to the primary while reads can be distributed to secondaries for scaling. Replica sets are configured and managed through shell helpers, and maintain consistency through an oplog and elections when the primary is unavailable.

Replication in MongoDB allows for high availability and scaling of reads. A replica set consists of at least three mongod servers, with one primary and one or more secondaries that replicate from the primary. The primary applies all write operations to its oplog, which is then replicated to the secondaries. If the primary fails, a new primary is elected from the remaining secondaries. Administrative commands help monitor and manage the replica set configuration.

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.

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.
