Re: kafka_2.9.2-0.8.2.0 - Topic marked for deletion

Hi Avinash, This is working as expected. Since delete topics is not enabled, they get marked for deletion, but never get deleted. Once you enable topic deletion (delete.topic.enable=true) the topics marked get delete. Once the topic is marked for deletion messages will still be available. It is w

Hi, I am trying to delete the kafka topic, verison I am using is 2.9.2-0.8.2. I am using dockerized kafka to delete the topic already created and didn’t set the “delete.topic.enable=true”. When I am listing the topics, it is giving as “ marked for deletion”. Is this a bug? However when I am s

Re: Load balancer for Kafka brokers

We use loadbalancers for our producer configurations, but what you need to keep in mind is that that connection is only used for metadata requests. The producer queries the loadbalancer IP for metadata for the topic, then disconnects and reconnects directly to the Kafka brokers for producing messag

Hi all, Two corrections to the invite: 1. The invitation is for November 18, 2015. *NOT 2016.* I was a little hasty... 2. LinkedIn has finished remodeling our broadcast room, so we are going to host the meet up in Mountain View, not San Francisco. We've arranged for speakers from H

Thanks for reply. Maybe it will be useful, I've noticed that after I tried to use client 0.9 with server 0.8.2 my data got corrupted. I wasn't able to read data from existing topics after I switched back to client 0.8.2. Cleaning kafka's and zk's data folders and creating topic from scratch solved

Partition assigned to a dead host - no rebalancing or topic delete possible?

Hello, If I understood topic deletion correctly, the controller waits for all brokers to ack the partition deletion. So if a partition is assigned to a dead broker, deletion will never happen. It seems that rebalancing pretty much works the same way, so we can't rebalance partitions (replaci
