codecentric mittendrin

Meetups, Stammtische, Hackathons, User Groups: Die codecentric ist weit mehr als die Summe ihrer Mitarbeiter und Projekte.

Hinter jeder erfolgreichen Software steht eine starke Community

Wissensvermittlung, Nachwuchsförderung und der fachliche Austausch auf Augenhöhe sind für uns Herzensangelegenheiten. Wir sind der Meinung: Geteilte Innovationsfreude ist doppelte Innovationsfreude.

Deshalb mischen sich codecentric-Mitarbeiter und -Mitarbeiterinnen gerne unter die Community – ob als Gastgeber, Redner oder Organisatoren diverser Veranstaltungen. Treffen Sie uns auf einem der folgenden Events!

IoT Data Storage: Apache Cassandra, MongoDB, Redis

In this meetup, you’ll learn more about three different Open Source NoSQL solutions and respective use cases for IoT data storage and streaming.

As usual, please complete your registration by sending an e-mail to (mandatory!)

There will be three short talks and a panel discussion on:

Apache Cassandra:
You maybe heard of companies like Apple, Netflix or Ebay. They own the largest Cassandra deployments in production. Apple’s cluster is one of the largest with 75000 Nodes holding over 10 PB of data and Netflix is processing over 1 trillion requests per day. But what is the technology behind those clusters? I like to give you a short dive into the technology, explain some use cases I solved with it and discuss about your challenges and opinions.

IoT in MongoDB:
Sensor-enabled objects are unleashing torrents of data previously unimaginable. Production lines to patrol cars to pacemakers. New revenue beckons. But sensor data is only useful if you can do something with it.
With MongoDB, you can make sense of sensor data, building applications never before possible. Faster. With less money.

Since its first source code commit just over ten years ago, Redis has managed to become one of the most popular open source databases. Due its tiny footprint, lightning-fast performance and linear scalability it’s rapidly becoming the database of choice for IoT and embedded use cases which need real-time performance from their data stores. Catering even more to this area, redislabs, the company behind this open source project, has recently launched a special edition called RedisEdge which combines the power of native Redis with time series, streaming and orchestration functionality. After a brief introduction to Redis as an in-memory multi-model database, the talk provides an in-depth discussion of this new offering by using several IoT use cases.


For Apache Cassandra:
Dominique Rondé is a big data pilot and an employee of the InsureTech startup freeyou. He works with all sorts of technologies around the topic of „big data“. However, most of his „flying hours“ he has collected on the Apache Spark, Confluent Kafka and DataStax Cassanda. In everyday life, he also deals with the possibilities of statistical analysis – in short, data science. As a true Java nerd since 2002, he writes the code of most of the jobs himself and runs them on cloud architectures.

For MongoDB:
Ewgeni Hersonski (Senior Enterprise Account Executive)
Ewgeni ispassionate about technology & disruptive use cases. As one of the very first local sales people in Germany (2015) for the market leader in NoSQL, Ewgeni has contributed towards the early customer footprints at MongoDB in Central Europe with some prominent customer stories.

Marc Martin (Sr. Solutions Architect)
Marc is passionate to enable companies to run their data driven applications in an efficient way to improve user experience and lower cost. He has 10+ years experience in managing applications and infrastructures. Before he came to MongoDB as a Solutions Architect, companies like Cisco AppDynamics, Riverbed and Compuware benefit from his broad experience. In addition he is a regular contributor within the user communities and an experienced speaker at user groups and conferences.

For Redis:
With more than 30 years of free and open source software experience, Dr. Christoph Zimmermann is one of Germany’s industry veterans in this field. In addition to his various community support activities including package management for a popular Linux distribution, serving on the board of a Linux User Group
in addition to frequent speaker engagements at events such as Chemnitzer Linux Tage, OpenRheinRuhr, etc. he is looking after the user base of the popular in-memory database Redis for the German-speaking countries both as a community liaison and pre-sales consultant.
