Inkless (KIP-1150) Apache Kafka Inkless implements diskless topics that write data directly to object storage, like AWS S3, using a leaderless architecture where any broker can handle any partition. This eliminates expensive local disk replication for topic data, though brokers still leverage small amounts of disk for metadata.
