Hello, Kanupriya Recently, I’ve implemented a histogram metric [1] in Apache Ignite. My implementation can work on a stream load.
It just counts events that is fall into the predefined intervals(buckets). I think histogram can be useful to measure consumer lag or similar metrics. So, If the community is interested we can have the same approach in Kafka.
