Kafka segment.index.bytes

Hi, I have a 2-node Kafka cluster. When I create a new topic it preallocates about 21MB for each partition: 10M /data/1-0/.index 0 /data/1-0/.log 10M /data/1-0/.timeindex 4.0K /data/1-0/leader-epoch-checkpoint And because I have many

Each empty partition has 21MB by default

Recently I noticed that when I create a new empty topic, each partition will have 21MB data! I even change the Kafka version from 0.11.3 to 2.1.0 but it shows the same behavior. For example, if I create a new topic using the command : kafka-topics.sh --zookeeper zoo1:2181 --create --topic test

Create empty topic result in massive data in the log-dir directory

Hi, I have a single node Kafka broker and 3-node Zookeeper cluster. When I create a new topic with 24 partitions using the command: kafka-topics.sh --zookeeper zoo3:2181 --create --topic test_topic --replication-factor 1 --partitions 24 It results in 481M data in the log-dir!? Actually, every

Kafka topic data automatically restore after deleting topics

Hi, I use Kafka 0.11.3 I delete topics from Kafka using the command *kafka-topic.sh *and after a while, I observer Kafka just mark topics for deletion while the property *delete.topic.enable *was true! So I stop Kafka cluster and delete the data log directory of Kafka using the command *rm -r

Hi, using Kafka 11.0.3 I set up a 2 node Kafka cluster on CentOS 7 with broker id 100 and 101. There is no firewall enabled. Both nodes can ping each other and establish the SSH connection successfully. When I start the cluster both broker successfully register their id into the zookeeper cluster

Re: Kafka sometime truncate new messages

In addition, I should say this behavior is for when topics are created automatically. On Mon, Jul 30, 2018 at 2:01 PM, Soheil Pourbafrani wrote: > I have a 3 node Kafka cluster. Upgrading Kafka version from 0.11.0.2 to > 0.11.0.3, I notice that Kafka sometimes truncate new message's topic

Kafka sometime truncate new messages

I have a 3 node Kafka cluster. Upgrading Kafka version from 0.11.0.2 to 0.11.0.3, I notice that Kafka sometimes truncate new message's topic. Here is the log: [2018-07-30 09:19:39,612] WARN [ReplicaFetcherThread-0-101]: Based on follower's leader epoch, leader replied with an unknown offset in

Kafka metrics attribute meaning

Hi, What is the exact meaning of the Kafka metrics attributes, for example, the attribute kafka.server:type=BrokerTopicMetrics,name=BytesInPerSec has the attributes MeanRate and OneMinuteRate. I am confused about the attribute OneMinuteRate! It is for the last minutes or for the whole broker

Hi and Thanks, Excuse me, The Kafka version is 0.11 and Zookeeper version is 3.4.10 I've check Zookeeper logs and sessions are expiring and renewing continuously there. I use the same Zookeeper cluster for Hadoop HA and it works well. I Answer the same question with more details in the following
