Session Title:
Multithreading vs. Asynchronous Programming: The Architectural Shift

Session Abstract:

Most mainstream languages started out with support for multithreading. Threads were considered lightweight but that term is relative. Threads were not ideal from the point of view of resource utilization and they often lead to higher cost of deployment. There has been a greater emphasis on asynchronous programming in recent times, due to the nature of applications and the architectural patterns they tend to favor.

In this presentation we will discuss how this shift is transforming both the programming languages, the ecosystems, and how we develop applications.

Session 2 details:

Session title:
Kafka Streams and KSQLDB

Session abstract:

Kafka is more than just a messaging pub-sub with storage. It goes beyond that, and with technology from Confluent open source, it has become a full-fledged data ETL and data streaming ecosystem. When we utter the words, Kafka, it is no longer just one component but can be an entire data pipeline ecosystem to transform and enrich data from source to sink. It offers different ways to handle that data as well.

In this presentation, we define:

• Streaming Concepts
• Using functional programming to manipulate your data
• Co-partitioning
• Aggregations

We then discuss KSQLDB. A SQL layer built upon Kafka Streams that provides a simple query
language to perform streaming operations:

• Persistent Queries
• Non-Persistent Queries
• Fault-Tolerance
