Hi , I am using Kafka 2.10_8.1.1 in the local mode , multi broker scenario. I wanted to establish how reliable is Kafka when it somes to guaranteed messaging , so i came with following results. wanted to know if this behaviour will be same distributed environment. The results are as follows : 1. When i start a topic and send messages to it via producer. I am able to receive it even after closing the producer. Seems fine.
2. When i start a topic and relay messages to it. and check the consumer console for that topic i can see the messages. when i stop the server , the consumer console also stops , upon starting the stopped server at that instant i can again see the remaining messages being relayed.seems fine. 3. When i close the kafka servers and also the zookeeper daemon. And start zookeeper and kafka again. I am able to check the data on topic from beginning as i had relayed it.again fine. 4. but when i close my Ubuntu virtual machine and i start Kafka and Zookeeper again. I can see the topics present in the kafka cluster. However all are default to 0 offset and data seems to have been lost.I can open the topics but i am unable to see the data that i had sent to the topics before shutting down my virtual machine. IS THIS THE WAY KAFKA FUNCTIONS IN DISTRIBUTED MODE ALSO?? Thanks, Siddharth Ubale
