Confluent Developer ft. Tim Berglund, Adi Polak & Viktor Gamov

Gwen Shapira (Core Kafka Software Engineer, Confluent) sits down to answer the questions you've had about event streaming, Apache Kafka®, Confluent, and everything in between. This includes creating tables in nested JSON topics, how to balance ordering, latency and reliability, building event-based systems, and how to navigate the tricky endOffsets API. She talks about the hardships of fencing Zombie requests, some of the talks given at previous Kafka Summits, and an important question from Ask Confluent #3.

In today’s episode of Streaming Audio, Tim Berglund sits down with Senior Applications Developer of Mobile Solutions Ramesh Sringeri to discuss Apache Kafka®—specifically two Kafka use cases that Children’s Healthcare of Atlanta is working on.

First, they discuss achieving near-real-time streams of data to support meaningful intracranial pressure prediction and managing intracranial pressure (ICP) in a timely manner to help the care team achieve better outcomes with traumatic brain injuries.

Children’s Healthcare of Atlanta is in the process of building machine learning models for predicting ICP values 30 and 60 minutes in the future. This will help the care team better prepare for handling potential adverse conditions, where elevated ICP values could lead to undesirable outcomes. The Children’s team is using Kafka, KSQL, and Kafka Streams programs to build a pipeline in which they can test their machine learning models.

Ramesh also shares about the work they’re doing to mitigate alarm fatigue for care providers. According to him, the current generation of monitoring devices are not equipped to set up multiple alarm conditions, and sometimes a combination of measures need to cross thresholds to be of concern. Children’s is able to leverage stream processing and KSQL to set up multiple conditions, reducing the number of meaningless alarms conditions that might condition care providers to ignore them.

One of the best parts of it all—with Kafka and KSQL, the Children’s team has been able to quickly build data processing pipelines and address business use cases without having to write a lot of code.

Sink and source connectors are important for getting data in and out of Apache Kafka®. Tim Berglund invites Hans-Peter Grahsl (Technical Trainer and Software Engineer, Netconomy Software & Consulting GmbH) to share about his involvement in the Apache Kafka project, spanning from several conference contributions all the way to his open source community sink connector for MongoDB, now part of the official MongoDB Kafka connector code base.

Zenreach is a company that makes tools to help retailers use digital marketing more effectively. If that sounds like a problem that only marketing people would be interested in, that’s because you don’t know what they do! There are all kinds of fascinating technology problems to solve by utilizing event streaming platforms to process data at volume. Rishi Dhanaraj, our guest today, worked at Zenreach as an intern, and took on a big pile of Python batch jobs, turning them into some really interesting Kafka Streams code. Listen in as he walks us through how he did it.
