NoSQL Analytics: JSON Data Analysis and Acceleration in MongoDB WorldAjay Gupte
In analytics world, when you need to process many millions or billions of documents to generate a single report. Novel techniques have been developed for exploiting modern processor architecture (larger on-chip cache, SIMD processing, compression, vector processing, columnar approach). Now, this technology is available to process your large JSON data. This talk will discuss analysis of JSON data using advanced data warehousing techniques and make it simple and seamless for the application/tool developer.
Webinar: Schema Patterns and Your Storage EngineMongoDB
How do MongoDB’s different storage options change the way you model your data?
Each storage engine, WiredTiger, the In-Memory Storage engine, MMAP V1 and other community supported drivers, persists data differently, writes data to disk in different formats and handles memory resources in different ways.
This webinar will go through how to design applications around different storage engines based on your use case and data access patterns. We will be looking into concrete examples of schema design practices that were previously applied on MMAPv1 and whether those practices still apply, to other storage engines like WiredTiger.
Topics for review: Schema design patterns and strategies, real-world examples, sizing and resource allocation of infrastructure.
To understand how to make your application fast, it's important to understand what makes the database fast. We will take a detailed look at how to think about performance, and how different choices in schema design affect your cluster performances depending on storage engines used and physical resources available.

Back to Basics 2017: Introduction to ShardingMongoDB
Sharding is a method for distributing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations by providing the capability for horizontal scaling.
Back to Basics Webinar 6: Production DeploymentMongoDB
This is the final webinar of a Back to Basics series that will introduce you to the MongoDB database. This webinar will guide you through production deployment.
Learn how to achieve scale with MongoDB. In this presentation, we cover three different ways to scale MongoDB, including optimization, vertical scaling, and horizontal scaling.
Back to Basics Spanish 4 Introduction to shardingMongoDB
Cómo MongoDB amplía el rendimiento de las operaciones de escritura y maneja grandes tamaño de datos
Cómo crear un sharded cluster básico
Cómo elegir una clave de sharding
One of MongoDB’s primary attractions for developers is that it gives them the ability to start application development without needing to define a formal, up-front schema. Operations teams appreciate the fact that they don't need to perform a time-consuming schema upgrade operation every time the developers need to store a different attribute.
Some projects reach a point where it's necessary to define rules on what's being stored in the database. This webinar explains how MongoDB 3.2 allows that document validation work to be performed by the database rather than in the application code.
This webinar focuses on the benefits of using document validation: how to set up the rules using the familiar MongoDB Query Language and how to safely roll it out into an existing, mature production environment.
Choosing a shard key can be difficult, and the factors involved largely depend on your use case. In fact, there is no such thing as a perfect shard key; there are design tradeoffs inherent in every decision. This presentation goes through those tradeoffs, as well as the different types of shard keys available in MongoDB, such as hashed and compound shard keys
When it comes time to select database software for your project, there are a bewildering number of choices. How do you know if your project is a good fit for a relational database, or whether one of the many NoSQL options is a better choice?
In this webinar you will learn when to use MongoDB and how to evaluate if MongoDB is a fit for your project. You will see how MongoDB's flexible document model is solving business problems in ways that were not previously possible, and how MongoDB's built-in features allow running at scale.
Topics covered include:
Performance and Scalability

Webinar: Working with Graph Data in MongoDBMongoDB
With the release of MongoDB 3.4, the number of applications that can take advantage of MongoDB has expanded. In this session we will look at using MongoDB for representing graphs and how graph relationships can be modeled in MongoDB.
We will also look at a new aggregation operation that we recently implemented for graph traversal and computing transitive closure. We will include an overview of the new operator and provide examples of how you can exploit this new feature in your MongoDB applications.
In a real life almost any project deals with the
tree structures. Different kinds of taxonomies,
site structures etc require modeling of
hierarchy relations.
Typical approaches used
● Model Tree Structures with Child References
● Model Tree Structures with Parent References
● Model Tree Structures with an Array of Ancestors
● Model Tree Structures with Materialized Paths
● Model Tree Structures with Nested Sets
Webinar: Schema Design and Performance ImplicationsMongoDB
One of the challenges that comes with moving to MongoDB is figuring how to best model your data.
While most developers have internalized the rules of thumb for designing schemas for relational databases, these rules don't always apply to MongoDB. The simple fact that documents can represent rich, schema-free data structures means that we have a lot of viable alternatives to the standard, normalized, relational model. Not only that, MongoDB has several unique features, such as atomic updates and indexed array keys, that greatly influence the kinds of schemas that make sense. Finally, different MongoDB schemas may result in wide differences in database size, query performance, and required hardware.
As your data grows, the need to establish proper indexes becomes critical to performance. MongoDB supports a wide range of indexing options to enable fast querying of your data, but what are the right strategies for your application?
In this talk we’ll cover how indexing works, the various indexing options, and use cases where each can be useful. We'll dive into common pitfalls using real-world examples to ensure that you're ready for scale.
MongoDB’s basic unit of storage is a document. Documents can represent rich, schema-free data structures, meaning that we have several viable alternatives to the normalized, relational model. In this talk, we’ll discuss the tradeoff of various data modeling strategies in MongoDB.
MongoDB for Time Series Data Part 2: Analyzing Time Series Data Using the Agg...MongoDB
The United States will be deploying 16,000 traffic speed monitoring sensors - 1 on every mile of US interstate in urban centers. These sensors update the speed, weather, and pavement conditions once per minute. MongoDB will collect and aggregate live sensor data feeds from roadways around the country, support real-time queries from cars on traffic conditions on their route as well as be the platform for real-time dashboards displaying traffic conditions and more complex analytical queries used to identify traffic trends. In this session, we’ll implement a few different data aggregation techniques to query and dashboard the metrics gathered from the US interstate.
Webinar: 10-Step Guide to Creating a Single View of your BusinessMongoDB
Organizations have long seen the value in aggregating data from multiple systems into a single, holistic, real-time representation of a business entity. That entity is often a customer. But the benefits of a single view in enhancing business visibility and operational intelligence can apply equally to other business contexts. Think products, supply chains, industrial machinery, cities, financial asset classes, and many more.
However, for many organizations, delivering a single view to the business has been elusive, impeded by a combination of technology and governance limitations.
MongoDB has been used in many single view projects across enterprises of all sizes and industries. In this session, we will share the best practices we have observed and institutionalized over the years. By attending the webinar, you will learn:
- A repeatable, 10-step methodology to successfully delivering a single view
- The required technology capabilities and tools to accelerate project delivery
- Case studies from customers who have built transformational single view applications on MongoDB.

2019 StartIT - Boosting your performance with BlackfireMarko Mitranić
A workshop held in StartIT as part of Catena Media learning sessions.
We aim to dispel the notion that large PHP applications tend to be sluggish, resource-intensive and slow compared to what the likes of Python, Erlang or even Node can do. The issue is not with optimising PHP internals - it's the lack of proper introspection tools and getting them into our every day workflow that counts! In this workshop we will talk about our struggles with whipping PHP Applications into shape, as well as work together on some of the more interesting examples of CPU or IO drain.
Domain-driven design (DDD) is an approach to developing software for complex needs by deeply connecting the implementation to an evolving model of the core business concepts.
This talk evalutes some easy ways to extract useful trending and capacity planning out of your existing monitoring investment. Using Nagios performance data, we examine simple behaviors with PNP4Nagios and graduate on to more insightful analytics with Graphite. With metrics in hand we look at the questions that IT /should/ be asking, such as:
* What sort of data should I trend?
* Why do I need to trend it?
* How do Operational or Engineering trends relate to Business or Transactional monitoring?
* How does this data impact our customer relationship and/or their bottom-line?
Finally, we look at creative ways to get profiling data out of your production systems with a minimum amount of effort from your development team.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
