 By default, Kafka consumers will read from the end of the stream rather than the beginning. This means any events queued before you begin running your consumer will not be read. If you started your consumer but it isn't receiving any events, try running your producer again while your consumer is polling. Alternatively, you can use Kafka's [`auto.offset.reset` consumer config](https://kafka.apache.org/documentation/#newconsumerconfigs) to make your consumer read from the beginning of the stream!
