With the rise of technologies like Apache Kafka, Apache Beam and Spark Streaming, the topic of stream processing is becoming increasingly popular. Commercial businesses are being formed around the associated open source technology, conference talks are filled with stories of migrations from batch Extract-Transform-Load (ETL) to stream processing, and blog posts and online discussions debate important concepts like if it is really possible to implement exactly once processing (as shown in the second article, the answer is yes, with caveats).
This InfoQ eMag aims to cut through some of the hype, and introduce you to core stream processing concepts like the log, the dataflow model, and implementing fault-tolerant streaming systems.

Streaming Architecture eMag includes:
- Exploring the Fundamentals of Stream Processing with the Data flow Model and Apache Beam - Frances Perry and Tyler Akidau discuss the Google Data flow model and the practical implementation of this within the Apache Beam stream processing platform
- Demystifying DynamoDB Streams: An Introduction to Ordering, Deduplication and Checkpointing - Akshat Vig and Khawaja Shams explore the implementation of Amazon DynamoDB Streams, and argue that understanding ordering and the effects of event duplication are vital for building distributed systems.
- Is Batch ETL Dead, and is Apache Kafka the Future of Data Processing? - Neha Narkhede argues that traditional batch ETL is ineffective for solving the requirements of modern data processing, and instead Apache Kafka can be used to create a real-time stream processing platform.
- Migrating Batch ETL to Stream Processing: A Netflix Case Study with Kafka and Flink - Shriya Arora presents a Netflix case study of a data processing migration to Apache Flink, and discusses that there are many decisions and tradeoffs that must be made when moving from batch ETL to stream processing.
- When Streams Fail: Implementing a Resilient Apache Kafka Cluster at Goldman Sachs - Anton Gorshkov discusses how the Goldman Sachs platform team designed and operated a resilient on-premise Apache Kafka cluster, which is the foundation of their stream processing capabilities.
