Hello everyone! Hope your September is off to a solid start! This week our roundup is stuffed with a variety of resources: a video to help you differentiate between different terms in the Kafka landscape, a 90-second explanation of Flink watermarks, a new whitepaper on Kora, a blog on Flink for developers already familiar with Kafka, and a way to manage your Confluent CLI plugins. Enjoy!
What if you want to list metadata from your Kafka cluster, topics, partitions, replicas and in-sync replicas?
You can run a command with the -L and -J flags using kcat:
kcat -b mybroker -L -J
-L is for list mode, and -J ensures JSON output.
The output will look like the following (‘replicas’ and ‘isrs’ listing the brokers on which the replicas and in-sync-replicas live):
6 topics: topic "pksqls-ddw45-processing-log" with 8 partitions: partition 0, leader 4, replicas: 4,9,2, isrs: 9,4,2 partition 1, leader 8, replicas: 8,10,0, isrs: 0,10,8 partition 2, leader 6, replicas: 6,11,4, isrs: 6,4,11 partition 3, leader 7, replicas: 7,3,8, isrs: 3,7,8 ...etc
