Should I use a document database?
Download as PPTX, PDF0 likes696 views
For the last 40 years or so, we used relational databases successfully in nearly all business contexts and systems of nearly all sizes. Therefore, if you feel no pain using a RDBMS, you can stay with it. But, if you always have to work around your RDBMS to get your job done, a document oriented database might be worth a look. RavenDB is a 2nd generation document database that allows you to write a data-access layer with much more freedom and many less constraints. If you have to work with large volumes of data, thousands of queries per second, unstructured/semi-structured data or event sourcing, you will find RavenDB particulary rewarding. In this talk we will explore some document database usage scenarios. I will share some data modeling techniques and many architectural criteria to help you to decide where safely adopt RavenDB as a right choice.

Know thy cost (or where performance problems lurk)
Know thy cost (or where performance problems lurk)Oren Eini Performance happens. Whether you're designed for it or not it doesn’t matter, she is always invited to the party (and you better find her in a good mood). Knowing the cost of every operation, and how it distributes on every subsystem will ensure that when you are building that proof-of-concept (that always ends up in production) or designing the latest’s enterprise-grade application; you will know where those pesky performance bugs like to inhabit. In this session, we will go deep into the inner working of every performance sensitive subsystem. From the relative safety of the client to the binary world of Voron.

Building Codealike: a journey into the developers analytics worldOren Eini
Codealike plugins in Visual Studio, Eclipse and Chrome, track developers while they code and perform analytic calculations at the millisecond level. For such write heavy workloads and using RavenDB as the main and only database was not without challenge. In this talk, we will reveal how we built and scaled such a solution, how we were able to improve performance with Voron and glance at our own mistakes and architectural choices down the line.

Compression talk
Compression talkIlya Ganelin In the engineering world, we don’t always have the luxury of owning our data pipelines end to end. If only we could influence those outside components… Well, we tried, and this our story - replete with failure, discovery, and the serenity of enlightenment. Join us on our journey as we learned more than we ever wanted to know about compression in different Apache projects, deployed our own ingestion pipeline in Apache Flume, and ultimately unified these in a robust framework built on Apache Apex handling 1 TB of data per day. We end with some reflections on the joys and tribulations of the open source realm and some key lessons for other large applications atop multiple Apache solutions.

Your Guide to Streaming - The Engineer's Perspective
Your Guide to Streaming - The Engineer's PerspectiveIlya Ganelin It feels like every week there's a new open-source streaming platform out there. Yet, if you only look at the descriptions, performance metrics, or even the architecture, they all start to look exactly the same! In short, nothing really differentiates itself - whether it be Storm, Flink, Apex, GearPumk, Samza, KafkaStreams, AkkaStreams, or any of the other myriad technologies. So if they all look the same, how do you really pick a streaming platform to solve the problem that YOU have? This talk is about how to really compare these platforms, and it turns out that they do have their key differences, they're just not the ones you usually think about. The way that you need to compare these systems if you're building something to last, a well-engineered system, is to look at how they handle durability, availability, how easy they are to install and use, and how they deal with failures.

NoSQL for great good [hanoi.rb talk]Huy Do NoSQL databases should not be chosen just because a system is slow or to replace RDBMS. The appropriate choice depends on factors like the nature of the data, how the data scales, and whether ACID properties are needed. NoSQL databases are categorized by data model (document, column family, graph, key-value store) which affects querying. Other considerations include scalability based on the CAP theorem and operational factors like the distribution model and whether there is a single point of failure. The best choice depends on the specific requirements and risks losing data if chosen incorrectly.

Horvath's presentation on dealing with XML ordinals over multiple files. It discusses how the SAS XML engine converts XML objects into SAS datasets with generated keys (ordinals) to represent parent-child relationships. However, these ordinals are not unique when concatenating datasets from multiple files. The presentation describes how to handle non-unique ordinals by finding the maximum ordinal from the previous file and adding it to the current file's values. It also discusses how the presenter addressed processing over 100 datasets by writing SAS code to generate the SAS code needed to handle the XML processing, rather than copying and pasting code manually.

1) SQL databases do not scale well for large amounts of distributed data, while NoSQL databases are designed for horizontal scaling across servers and partitions.
2) Common types of NoSQL databases include document, key-value, graph, and wide-column stores, each with different data models and query approaches.
3) NoSQL databases sacrifice consistency guarantees and complex queries for horizontal scalability and high availability. Eventual consistency is common, with different consistency models for different use cases.
NoSQL
NoSQLkirandanduprolu This document discusses NoSQL databases and how they provide alternatives to SQL databases for managing large datasets. It notes that NoSQL databases are designed for high performance, unlimited scalability, and high availability even on unreliable hardware. The document outlines several types of NoSQL databases, including key-value stores, document stores, and BigTable clones. It argues that NoSQL databases are better suited than SQL databases for applications requiring flexible schemas, large volumes of data, or high write volumes.

Zapping ever faster: how Zap sped up by two orders of magnitude using RavenDB
Zapping ever faster: how Zap sped up by two orders of magnitude using RavenDBOren Eini
Join a real uplift experience with Hagay Albo, the CTO of the Zap/Yellow Page Group in Israel, in which he explains how his team was able to take a legacy (slow and hard to modify) group of sites and make them easier to work with, MUCH faster and greatly simplified the operational environment.
By prioritizing high availability, flexible data modeling and focusing on raw speed Zap was able to reduce its load times by Two Orders of Magnitudes. Using RavenDB as the core engine behind Zap's new sites had improved site traffic, reduced time to market and made it possible to implement the next-gen features that were previously beyond reach.

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?

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 AI
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 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.
