Headless Data Architecture, Explained for Developers

This post introduces and explains the concept of a 'headless data architecture,' which decouples data storage, management, and access from the services that interact with it. It details how Apache Kafka serves as the streaming layer and Apache Iceberg, with its table storage, catalog, transaction, and time-travel capabilities, serves as the table layer. The post emphasizes the benefits of this architecture, including reduced data duplication, simplified coordination, and the flexibility to choose processing engines. It also contrasts this approach with traditional data lake architectures, highlighting its modularity and pluggability. The post mentions connectors like Kafka Connect and managed services like Tableflow for materializing streams into Iceberg tables.
