Apache Cassandra is a scalable database with high availability features. But they come with severe limitations in term of querying capabilities. Since the introduction of SASI in Cassandra 3.4, the limitations belong to the pass. Now you can create performant indices on your columns as well as benefit from **full text search** capabilities with the introduction of the new `LIKE %term%` syntax. To illustrate how SASI works, we'll use a database of 100 000 albums and artists. We'll also show how SASI can help to accelerate analytics scenarios with Spark using SparkSQL predicate-pushdown

I've just watched this very interesting talk by Martin Kleppmann Turning the database inside out with Apache Samza - por Garajeando

In this talk, we present Apache SAMOA, an open-source platform for mining big data streams with Apache Flink, Storm and Samza. Real time analytics is becoming the fastest and most efficient way to obtain useful knowledge from what is happening now, allowing organizations to react quickly when problems appear or to detect new trends helping to improve their performance. Apache SAMOA includes algorithms for the most common machine learning tasks such as classification and clustering. It provides a pluggable architecture that allows it to run on Apache Flink, but also with other several distributed stream processing engines such as Storm and Samza.

Interesting talks/podcasts/presentations that I watched during may:RailsConf 2015 - Nothing is Something Another great talk about OO Design from Sandi Metz.Microservices: Software that Fits in Your Head Dan North at Craft Conf 2016 Ruby Midwest 2011 - Keynote: Architecture the Lost Years Robert C Martin (uncle Bob). The classic talk about how the boom of the web derived in a lack of macro design/architecture for our applications and the problems generated.YOW! Nights March 20...

What’s important about a technology is what you can use it to do. I’ve looked at what a number of groups are doing with Apache Hadoop and NoSQL in production, and I will relay what worked well for them and what did not. Drawing from real world use cases, I show how people who understand these new approaches can employ them well in conjunction with traditional approaches and existing applications. Thread Detection, Datawarehouse optimization, Marketing Efficiency, Biometric Database are some examples exposed during this presentation.

In dog years… err… Open Source years, the Groovy programming language project is a very mature and successful one, as its 4.5 million downloads a year can attest. The Groovy language is certainly the most widely deployed alternative language of the JVM today. But how do we go from a hobby night & week-end project to professionally company sponsored? And back again to hobby mode but joining the wider Apache Software Foundation community? Guillaume will guide you through the history of the project, its latest developments, and its recent news, outlining the importance of a community around an Open Source project. Also, we’ll discuss what it means to contribute, when it’s your hobby or as a paid committer — what does it change? What it means to join the Apache community, what the impact of professional Open Source is, and more.
