Diskless Kafka, introduced through Apache Kafka's KIP-1150, represents a significant shift in data streaming by moving replication from local broker disks to cloud-based object storage such as Amazon S3. This change, facilitated by Aiven's "Inkless" implementation, promises to reduce the total cost of ownership by up to 80% by eliminating the need for costly cross-zone replication, which is a major expense in cloud environments like AWS. While Diskless Kafka maintains compatibility with existing Kafka APIs and offers the flexibility to operate both traditional low-latency and cost-optimized diskless topics within the same cluster, it presents a trade-off with slightly higher latency, suitable for non-latency-critical applications such as logging. Despite the "Diskless" moniker, brokers still require local disks for metadata and temporary operations, but the innovation lies in how user data is managed. This evolution enables new possibilities for Kafka users, offering both cost savings and the potential for new use cases without the need to migrate from existing Kafka infrastructure. The community's participation in the ongoing development is encouraged through engagement with the KIP-1150 discussion, signaling a collaborative effort in shaping the future of Kafka.
