Karafka is a Ruby and Rails framework that simplifies the development of Apache Kafka-based applications. Among its varied features, the Filtering API provides enhanced control over the data flow.The crux of this article is about managing offsets - unique identifiers for messages within Kafka's partitions. Often, there's a need to manage offsets alongside database operations within a transaction, especially when handling potential process crashes and anomalies, minimizing the risk of double processing.For instance, if a SQL operation concludes successfully but the offset commit fails due to a crash, data could be processed again, leading to potential duplications or data integrity issues. Integrating offset management with database transactions using Karafka's Filtering API can help tackle this problem. It ensures the offset progress is tracked within the database transaction, maintaining data integrity even in crashes.We'll explore this concept further in the coming sections, highlighting its practical implications and benefits.
