Dublin Java User September 2016
Building Java Applications with Cassandra
Spark and Cassandra
DataStax Global Director Of Training, Tim Berglund
(Doors 18:15 and Presentation at 19:00)
Running a little later than scheduled, we're incredibly pleased to welcome back Tim Berglund to the Dublin Java User Group's September stage at TechMeetup.Space.
Session 1 – Building Java Applications with Cassandra
So you’re a JVM developer, and you’ve got a big problem to solve. You’ve got way more data than can fit on a single database server, and it’s no passive collection of facts to analyze: this is a transactional application that modifies data frequently and with unforgiving latency SLAs. You need Cassandra.
In this talk, we’ll look at how Cassandra operates as a distributed database, and what sorts of challenges it presents to the application developer. Even better, we’ll see what the code actually looks like to perform ordinary database queries against a database like Cassandra. Come to this session to see what a distributed, non-relational database really looks like.
Tim is a teacher, author, and technology leader with DataStax, where he serves as the Director of Education.
He can frequently be found at speaking at conferences in the United States and all over the world. He is the co-presenter of various O’Reilly training videos on topics ranging from Git to Distributed Systems, and is the author of Gradle Beyond the Basics.
He tweets as @tlberglund , blogs very occasionally at TimBerglund.com , and lives in Littleton, CO, USA with the wife of his youth and their youngest child
A Message from Our Beer and Pizza Sponsor Stackand.Co
Are you a Java Developer who wants X-Training to Scala? You Bet!!
We are now interviewing for a new funded multinational making its place in Ireland. Check the 'brief' here now and then call me, Gerry Nolan, on +353 (0)1 209 1919 for full company details.
Session 2 – Spark and Cassandra
Apache Cassandra is a leading open-source distributed database capable of amazing feats of scale, but its data model requires a bit of planning for it to perform well. Of course, the nature of ad-hoc data exploration and analysis requires that we be able to ask questions we hadn’t planned on asking—and get an answer fast. Enter Apache Spark.
Spark is a distributed computation framework optimized to work in-memory, and heavily influenced by concepts from functional programming languages. It’s exactly what a Cassandra cluster needs to deliver real-time, ad-hoc querying of operational data at scale.
In this talk, we’ll explore Spark and see how it works together with Cassandra to deliver a powerful open-source big data analytic solution .
