Apache Kafka, known for its robust message tracking and retention capabilities, also accommodates the deletion of data to comply with GDPR requirements, such as the right to be forgotten. Kafka's immutable log storage presents challenges for data deletion, but the platform supports message expiration and an Admin API for explicit deletions. Businesses often utilize Kafka for long-term data storage in Event Sourcing architectures, necessitating GDPR-compliant management of enduring data. Compacted topics allow for explicit message deletion or replacement via their keys, similar to techniques used in databases like Cassandra. This can be achieved by writing a new message with a null value for deletion. Additionally, encryption per user, proposed by Daniel Lebrero, offers an alternative by rendering data unintelligible once the encryption key is deleted. Kafka's integration with databases through Connectors allows for data deletion propagation, especially when using Change Data Capture. The compaction process can be configured for continuous operation with bandwidth limitations to maintain system performance. Kafka topics can be both compacted and have expiration settings for optimal data management, with the platform's latest version, 3.8.0, bringing further enhancements and features.
