RavenDB Conference VideosReplication changes in 3.5

time to read 1 min | 71 words

In this talk from the RavenDB conference, Jonathan Matheus is talking about the Replication in RavenDB 3.5 and the changes from previous versions.

RavenDB 3.5 breaks new ground in providing high availability with its consensus-based clustering. In this talk, we'll take a deep dive into using RavenDB in a clustered environment and discuss how it differs from the traditional replication model offered in previous versions.

RavenDB Conference VideosDelving into Documents with Data Subscriptions

time to read 1 min | 89 words

In this talk from the RavenDB conference, Kijana Woodard is talking about using subscriptions to process data reliably.

You've got documents coming in fast. There's long running processing that needs to happen, but you don't want users to have to wait when they submit data. Don't worry! Data Subscriptions provide a way to reliably process documents asynchronously from the rest of your application. In this talk, we'll cover the basics of Data Subscriptions to get your processing jobs running quickly and efficiently.

RavenDB Conference videosBuilding Codealike

time to read 1 min | 98 words

In this talk from the RavenDB conference, Federico Lois is discussing building Codealike,a collaborative platform for developers analytics.

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.

RavenDB Conference videosImplementing CQRS and Event Sourcing with RavenDB

time to read 1 min | 115 words

In this talk from the RavenDB conference, Elemar Júnior is talking about CQRS and using RavenDB for event souring.

CQRS stands for Command Query Responsibility Segregation. That is, that command stack and query stack are designed separately. This leads to a dramatic simplification of design and potential enhancement of scalability.

Events are a new trend in software industry. In real-world, we perform actions and these actions generate a reaction. Event Sourcing is about persisting events and rebuilding the state of the aggregates from recorded events.

In this talk I will share a lot of examples about how to effective implementing CQRS and Event Sourcing with RavenDB

RavenDB Conference videosZapping ever faster

time to read 1 min | 138 words

In this post from the RavenDB conference, Hagay Albo talks about substantial performance gain as a result of using RavenDB.

oin 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.

RavenDB Conference videosShould I use a document database?

time to read 1 min | 196 words

In this talk from the RavenDB conference, Elemar Júnior is talking about the differences between relational and document databases, and how you can utilize RavenDB for best effect.

I’ll hint that the answer to the question in the title is: Yes, RavenDB.

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 particularly 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.

RavenDB Conference videosKnow Thy Costs

time to read 1 min | 131 words

In this talk from the RavenDB conference, Federico Lois is discussing the kind of performance work and optimizations that goes into RavenDB.

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.

RavenDB Conference videosLessons from the Trenches

time to read 1 min | 94 words

In this talk from the RavenDB conference, Dan Bishop is talking about lessons learned from running RavenDB in production for a very long time.

It's easy, fun, and simple to get a prototype application built with RavenDB, but what happens when you get to the point of shipping v1.0 into Production? Many of the subtle decisions made during development can have undesirable consequences in Production. In this session, Dan Bishop will explore some of the pain points that arise when building, deploying, and supporting enterprise-grade applications with RavenDB.

RavenDB Conference videosRavenDB Embedded at Massive Scales

time to read 1 min | 117 words

In this talk from the RavenDB conference, Rodrigo Rosauro is talking about deploying RavenDB at massive scale, to over 36,000 locations and a total number of machine that exceed half a million.

One particular (and often forgotten) use-case for RavenDB is its usage as an embedded database. This operation mode allows application providers to abstract the complexity of database administration from their end-users while, at the same time, providing you a fully functional document store.

During this talk we will explore the challenges faced while deploying RavenDB in a massive number of machines throughout the globe (aiming at hundreds of thousands), and how RavenDB improved the capabilities of our application.

RavenDB Conference videosRavenDB for the Modern Web Developer

time to read 1 min | 87 words

In this talk from the RavenDB conference, Judah is discussing using RavenDB for web development, including how to postpone the robot apocalypse by finding some love to young robots lose in the javascript maze.

Modern web development is uniquely fast-paced, demands rapid development and responsiveness to changes. But our databases have been stuck in the 1970s with rigid schemas and antiquated query languages. Enter RavenDB: flexible, fast, designed for the 21st century. It's the perfect side to your web development dish.
