[Event canceled] March meetup: all about Kafka streams and Cassandra 4.0

Join Bucharest BigData to find out more about Kafka Streams and the newest Cassandra release. RSVP and let’s meet on March 24, starting at 18:00!


Event agenda

  • 18:00 – 18:30 Getting together
  • 18:30 – 19:20 Kafka Streams – a database inside out, Miron Brezai, Software Architect @ eSolutions

Kafka Streams is the easiest way to write scalable stream processing microservices. In this presentation, I will go over the architecture of Kafka Streams, will explain KStream and KTable – their differences and similarities and the local storage of Kafka Streams, how we can make joins between streams and tables and how to aggregate objects based on events grouped by id. Basically is about processing and joining infinite database tables.

  • 19:20 – 20:00 Cassandra 4.0 – What to Expect, Aleks Volochnev, Developer Advocate @ Datastax

Apache Cassandra has been a driving force for applications that scale for over 10 years. This open-source database now powers 30% of the Fortune 100. Now is your chance to get an inside look, guided by the company that’s responsible for 85% of the code commits. You won’t want to miss this deep dive into the database that has become the power behind the moment — the force behind game-changing, scalable cloud applications.

February meetup: data science 101 and MQTT + Kafka

Join us to talk about ML tools to be used, ML basics to know and how a day goes by in the life of a data scientist with Andras and how the data flow of an IoT system could look like using MQTT and Kafka with Virgil. RSVP and let’s meet on February 27, starting at 18:30!


Event agenda

  • 18:30 – 19:00 Gathering and socialization
  • 19:00 – 19:40 What a data scientist can teach you in 40 minutes: the basics of ML, the tools, the daily stuff; Andras Palfi @ UiPath

The objective of the presentation is to teach the audience what Data Science is and the various kinds of activities a Data Scientist performs. It will familiarize learners with basic concepts of machine learning, go into detail about the type of Data Scientists that exist together with how they spend their time and what tools they use.

  • 19:30 – 20:20 MQTT & Kafka & Encryption = Secure IoT communication & Data Flow; Virgil Borcea @ eSolutions

In this presentation, I want to show you how we have enabled the communication of Mobile Applications with IoT devices and what’s the data flow in an IoT ecosystem. We will also give Security tips for a production solution. A demo will include the flow API Calls -> Kafka -> MQTT Broker -> IoT Device

Spark v2.2 Workshop

Do you want to learn more about the newly introduced features in Spark v2.2 and about Spark’s integration with Kafka and Cassandra for streaming pipelines? RSVP here now and save your front row place on November 3, starting 3:30 PM!


About the event

  1. The first part of the workshop will cover Spark SQL with Scala, specifically the limited toy examples emphasized by Spark documentation and tutorials. Spark SQL, used in isolation, can realistically only be used for such didactic use cases – when ingesting real-world datasets, Spark SQL will very quickly show its limitations and therefore some more powerful techniques are needed.
  2. The second part of the workshop will cover the techniques mentioned above, without which Spark SQL is largely ineffective. This section of the workshop will be about sharing lessons learned the hard way, and experience gathered in the trenches of the real world.
  3. The third part of the workshop, titled “Machine Learning By Example”, will cover multiclass classification using SparkML’s Pipeline API with Scala. SparkML is the machine learning module that ships with Spark.
  4. During the remaining time, the trainer will focus on a Scala/Spark Streaming application that ingests data from Apache Kafka (an open-source, high-performance, distributed message queue), performs streaming analytics, then saves the analytics results back into Kafka.

If participants want to dive deeper into high-complexity topics, the trainer will instead focus on live coding ad-hoc demos.


Event agenda

  • 15:30 – 16:00 Welcome
  • 16:00 – 17:00 SQL with Scala
  • 17:00 – 18:00 Spark SQL techniques
  • 18:00 19:00 Machine Learning By Example
  • 19:00 – 20:00 Scala/Spark Streaming application
  • 20:00 – 21:30 Networking
