The Kafka cluster retains all published messages—whether or not they
have been consumed—for a configurable period of time. For example if the
log retention is set to two days, then for the two days after a message is
published it is available for consumption, after which it will be discarded to
free up space. Kafka's performance is effectively constant with respect to data
size so retaining lots of data is not a problem.

the consumer: normally a consumer will advance its offset linearly as it reads
messages, but in fact the position is controlled by the consumer and it can
consume messages in any order it likes. For example a consumer can reset to an
older offset to reprocess.

This combination of features means that Kafka consumers are very
cheap—they can come and go without much impact on the cluster or on other
consumers. For example, you can use our command line tools to "tail" the
contents of any topic without changing what is consumed by any existing
consumers.
