%description
Apache Kafka is publish-subscribe messaging rethought as a distributed commit log.
A single Kafka broker can handle hundreds of megabytes of reads and writes per second
from thousands of clients. It can be elastically and transparently expanded without downtime.
Data streams are partitioned and spread over a cluster of machines to allow data streams
larger than the capability of any single machine and to allow clusters of co-ordinated consumers
