After travelling the European map and speaking at the big NoSQL events, Luca gave one of the Keynote speeches at NoSQL matters 2012!
NoSQL Adoption – What’s the Next Step?
Today, many companies are already using a NoSQL solution to handle a piece of data. What is the next step? Probably the adoption of NoSQL as a total replacement of Relational DBMS. To reach this Goal, NoSQL solutions have to support multiple models and features, that are already available in Relational DBMS. The challenge has started.

Talk 2: NewSQL! NoSQL under attack
One of the biggest credits NoSQL deserves is to unveil the weaknesses of classical database systems. But it looks like the classic relational world has listened to these hints: Now they promise to provide scalability with full transactional support while retaining the familiar relational model with SQL access. This new group of systems is now referred to as “NewSQL” and leads to a fruitful competition between the two worlds. This talk summarizes the newest of NoSQL and shows systems that lead the NewSQL space.

NewSQL Database for New Real-Time Applications
New real-time applications require databases that can process larger volumes of transactions than what is possible with current market-leading relational databases. And while more recent NoSQL databases are able to scale out so that they can handle extremely large volumes of data, they cannot guarantee consistency. While this is acceptable for some types of data such as social network bulletin boards, it does not work for most business critical data such as stock quantities or money. But what if there was a happy medium? A database that could process millions of transactions on a single machine, while maintaining the consistency that these business critical applications require? There is! In this presentation, Peter will describe a different kind of a NewSQL database, which will process millions of ACID-compliant transactions while scaling in on a single machine to fully ensure consistency. He will also delve into the technical differentiators between traditional relational databases, NoSQL and NewSQL databases and what applications they are best-suited for.

NoSQL: Back to the Future or is it Simply yet Another Database Feature?
NoSQL is about to reach the tip of the hype cycle. Therefore, it is time to take a break and thoroughly analyze the NoSQL trend.
This talk will trace NoSQL back to the early days of database approaches and will then reflect on NoSQL‘s current state and future: Is NoSQL as a technological approach to data storage just a feature or is it a unique category of its own? Is NoSQL a fundamentally new thing that will stay as a trend? What are current NoSQL systems lacking? Will there be a technology or trend that could disrupt NoSQL?

Hypertable – The Storage Infrastructure behind One of the World‘s Largest Email Services
Rediff.com India (Nasdaq: REDF) is one of India‘s top Internet portals, providing email, search, news, entertainment and shopping services to India and the global Indian community. With over 100 million registered users, Rediff.com is one of the largest Indian Internet portals and one of the top email providers worldwide. Rediffmail is Rediff.com‘s popular email service and has experienced steady growth ever since it was launched in 1998. Architected for high availability, Rediffmail is a geo-distributed application served out of three separate data centers. By 2011, the request load generated by the application had begun to overwhelm the underlying storage system, causing frequent outages. Metadata updates in connection with inbox management turned out to be the primary culprit, generating over 75 percent of the storage system request volume. In late 2011, the Rediffmail engineering team re-architected the system on top of Hypertable, solving the inbox management problem and eliminating the associated outages.

Alexandre is NantesJS creator, Web Developer, Web Architect, and Community Manager at 4D, he gives presentations about JavaScript, the Server-Side JavaScript, NoSQL, and Wakanda. Alexandre participates in Web Standards mailing lists, makes technical recommendations to anything related to HTML, JavaScript or HTTP, and works to promote JavaScript as a professional language.
Wakanda: NoSQL for Model-Driven Web Applications
Developing a business web application is still a long process in 2012. Model-Driven Development is at the heart of:
- Requirements design for the contractor and the product manager
- Productivity for the developer
- Consistency and security for the end-user
- Evolution toward future applications
The Wakanda platform – with its NoSQL object datastore – intends to let you create such model-driven applications. The presentation will explain and show how to create the application model, with its business and security rules, coded once, then made available everywhere without being “bypassable”. You will see enhancements to the maintenance and debug process, as everything is centralized in the model on the server-side (while maintaining potential pre-validation on the client to decrease the load on the server).
To add even more consistency, the same language is used everywhere: JavaScript.
Konstantin Osipov
Konstantin Osipov had been a software engineer and engineering lead at MySQL since 2003. His main areas in the server were locking, parsing, execution of prepared statements and stored procedures. He was the implementer of support for Dynamic SQL in 5.0. In 2010 Konstantin quit Oracle to join development of a new NoSQL solution: Tarantool. In his other life Konstantin is a Moscow dweller with a not uncommon combination of such hobbies as yoga, running and computers.
Tarntool/Box: Transactional NoSQL Database for Most Volatile Web Data
Tarantool/Box is an open-source, transactional database server. Its key property is high efficiency (hundreds of thousands of requests per second on a commodity server) combined with high level of customization, achievable with Lua stored procedures.
Tarantool utilizes lock-free cooperative multi-tasking environment and asynchronous I/O to achieve minimal overhead per request. Each request, which can be either a simple GET/PUT, classical for NoSQL systems, or a custom data access script in Lua, is run in a multi-version transactional environment.
The key advantage of Tarantool/Box, compared to existing open-source NoSQL solutions, is the ability to execute parts of application business logic automatically on the server, with sufficiently high performance. Sufficiently means that you may never need to shard.
Tarantool is written in C and Objective C. The server code and Drivers are available under terms of simplified BSD license.
In the talk I’ll demonstrate key features of the server using examples in Lua, Ruby and Erlang.

ArangoDB
This talk will give an introduction to ArangoDB. ArangoDB is a new open source NoSQL database, whose goal it is to be a powerful universal database. It allows flexible data modelling: as key-value pairs, documents or graph data. It allows complex queries through an elegant query language. An embedded JavaScript interpreter allows you to add functionality to the database for transactions, complex manipulations of the objects, treating AvocadoDB as a complete application server – database stack. ArangoDB guarantees durability through MVCC with append-only journals and zero-administration availability through synchronous replication. It utilizes main memory and SSDs to deliver maximal performance. Even though ArangoDB is still a young project, it has already attracted international attention, especially in Japan and the USA. The community is currently working on APIs for Python, D, Ruby, Java and node.js.

From Tables to Graph. Recommendation Systems, a Graph Database Use Case Analysis
Recommendation engines have changed a lot during the last years and the last big change is NoSQL, especially Graph Data- bases. With this presentation we intend to show how to build a Graph Processing technology, based on our experience in doing that for environments like Digital Libraries and Movies and Digital Media. First, we will introduce the state of the art on context aware Recommendation Engines, with special interest on how peo- ple are using Graph Processing, NoSQL, systems to scale this kind of solutions. After an introduction to the ecosystem, the next step is to have something to work with. So we will show the audience how to build a Recommendation Engine with a few steps.
The demonstration part will be made using the next technology stack: Sinatra as a simple web framework. Ruby as a programming language. OrientDB, Neo4j, Redis, etc. as a NoSQL technology stack. The result of our demonstration will be a simple engine, accessible through a REST API, to play and extend, so that atten- dants can learn by doing.
In the end our audience will have a full in- troduction to the field of Recommendati- on Engines, with special interest on Graph Processing, NoSQL, systems. Based on our experience making this technology for large scale architectures, we think the best way to learn this is by doing it and having an example to play with.

Building Hybrid Applications with MongoDB, RDBMS & Hadoop
Business moves fast, very fast. It’s driven by making decision based on facts, but how do you deal with facts that are hours or days old? Periodic data warehouse loads and ETL process no longer scale to meet the increasing business needs in the web economy. Today, modern organizations are combining high performance operational data stores like MongoDB with traditional business intelligence RDBMS solutions to create a hybrid than solves the business need to have fast accurate data for decision making with the ability to interpret and analyze data in every way.
This talk will try to answer the questions
- What are the business benefits using this approach?
- Which problem can now be solved using this approach?
- How can this solution meet the Needs of Business?
- Customer use cases
Axel Morgner
Axel is founder of structr—a free, open-source CMS and Content Management Framework based on the graph database Neo4j. He previously founded inxire GmbH, and served as a consultant and project manager at Oracle. After leaving the enterprise SQL world behind in 2010, he enjoys now being back to cutting egde technology every day. He’s based in Frankfurt/Main, Germany.
Structr – A CMS Implementation based on a Graph Database
This session offers a close look at the implementation and benefits of utilizing a graph database, namely Neo4j, to serve as a CMS back-end. As we will see, the classic CMS ORM approach has several drawbacks, such as the inherent complexity of mapping CMS content to tables, or the inflexibility of relational databases for semi-structured CMS data. Graph databases address these challenges by directly storing CMS data as a graph structure in a natural and trivial way, and allowing to alter the CMS schema at runtime. Along with a live Demonstration the talk will provide a short introduction of general CMS use-cases and requirements, and will cover the specific strategy and data model used to build open-source CMS structr, which can be applied to other cases as well.

NoNoSQL@Google
Relational Database Management Systems were hardly ever used at Google to store logs data. But SQL as a data exploration language has been becoming increasingly popular over the last years. In fact, nowadays the fast majority of data analysis jobs at Google are expressed by SQL queries. In this talk I give a brief history of data storage and exploration techniques deployed at Google and describe the current state of the art. I furthermore explore why SQL became so popular and illustrate my main conclusion: SQL‘s simplicity and conciseness rules over all other (currently available) alternatives.

Crazy NoSQL Data Integration with Pentaho
With the arrival of a new armada of NoSQL databases chances are increasing constantly that you will have to integrate data from one of them. So in this talk I‘ll be going over crazy data integration between various relational and NoSQL databases.
- Parallel extraction and load of MySQL data into Hadoop
- Real-time update of PostgreSQL tables based on changes in CouchDB
- Extracting JSON information from MongoDB to load it into MySQL
- Populating elasticsearch results with product information
Obviously, I‘ll be giving a short introduction Pentaho Data Integration (Kettle), the graphical programming and design involved. I‘ll also be giving a short overview of the NoSQL landscape so that you can get an idea of what‘s going on in that space.

UML as a Scheme Candidate for Graph Databases
During the lifetime of a building, a huge quantity of information will be captured by multiple actors: owners, managers, users, architects, electricians, plumbers, etc. As most of this information is not shared between these persons, the same analysis, verifications or measurements have to be done multiple times. SpatioData is a research project aiming at the development of a collaborative platform to support the effective sharing of such diverse data.
In order to reach this ambitious goal, it is important to provide the users with devices suiting their needs (mobile or station) and interfaces adapted to their specific activities. These various client applications will communicate to a centralized database through WebServices exhibiting a common data model.
The data model of such an application has to address many problems. Amongst those are:
- Complexity of the data model to represent the different aspects of the buildings, their actors, and the activities of the actors.
- Communicability, to ensure that developers willing to build client applications will understand and use the provided model in the same way.
- Extensibility, to provide client-side developers with a mechanism to add their own data schemes in the database.
- Flexibility, required in a research environment, where multiple questions are being co-resolved in parallel.
UML has been chosen for the representation of our data model, as it is a formalized and well-known format in the developers community. But instead of fully developing the data model, then implementing it and providing dedicated services to it, an original approach has been adopted, in the form of UML-oriented WebServices independent of any specific model. This solution has been built on top of a graph database (Neo4J) in a simple but powerful way, providing answers to the given problems above.
This communication will detail the complete system architecture and the process designed on top of it, to make sure thirdparty developers can take full advantage of this platform.

This talk will present the storage engine at the core of Cassandra, motivating the use of a structure similar to a Log-Structured Merge Tree rather than of a usual B-Tree and its implications for the data model. We will also introduce most of the current features of that engine (secondary indexes, integrated caching, TTL etc.) including recent developments introduced in Cassandra 1.0 like compression/checksumming and the new leveled compaction.

Bernd Ocklin joined the MySQL organization, MySQL Cluster, in September 2005. He first worked as a solution architect for highly available distributed databases and cluster solutions. Now he runs the MySQL Cluster development at Oracle. Bernd has designed and programmed data mining software in addition to writing a database core prior to using MySQL databases. which has provent to be useful in big scale data processing.
MySQL Cluster: Scaling to Billion Database Queries per Minute
MySQL Cluster is the high availability, low latency storage engine with auto-sharding and real-time capabilities, used worldwide to ensure that hundreds of millions of mobile phone users are always reachable.
This mature and proven technology is gaining rapid adoption in the web due to its simple scaling model, performance/and integrated HA that are needed to ensure that web services can evolve rapidly. MySQL Cluster has many attributes that make it ideal for new generations of dynamic, highly scalable applications, including:
- Auto-sharding across commodity hardware for write-scalability
- Cross-data center geographic synchronous and asynchronous replication with eventual consistency
- Online scaling and schema evolution
- SQL and NoSQL interfaces
This session looks at the existing NoSQL access methods for MySQL as well as the latest developments for the MySQL Cluster storage engine. You can get the best of both worlds – persistence, consistency, rich queries, high availability, scalability and simple, flexible APIs and schemas for agile development.
Learn how cluster as a globally distributed database engine is used in mobile phone networks, how web services profit from its scaleable fully event driven architecture.
