Quick profiling of data in Apache Kafka using kafkacat and visidata
ksqlDB is a fantastically powerful tool for processing and analysing streams of data in Apache Kafka. But sometimes, you just want a quick way to profile the data in a topic in Kafka. I wrote about this previously with a convoluted (but effective) set of bash commands pipelined together to perform a
GROUP BY on data. Then someone introduced me to
visidata, which makes it all a lot quicker!
