Kafka data can be stored on a Dbase instead of file system?

Hi Guys,

I wanted to know if we can store data sent to consumers via brokers on to
any database like how ActiveMQ persists data to kahaDB or any other Db like
PostGRE,SQL etc.

Also,when the broker is sending message to consumer and consumer fails, so
when the consumer is up again will the consumer pick data from where it
last left or will it start reading from beginning if i have set the
consumer from beginning while coding the consumer.

Thanks,
