kafka中如何創建topic？

通過如下的命令創建topic

kafka-topics.sh \
    --bootstrap-server <Kafka集羣地址> \
    --create \
    --topic <Topic名稱> \
    --partitions <分區數> \
    --replication-factor <副本因子>

 

 

示例

bin/kafka-topics.sh \
  --bootstrap-server 122.120.45.214:34991 \
  --create \
  --topic testtop01 \
  --partitions 3 \
  --replication-factor 1

 

 

創建之後，通過以下的命令查看創建好的topic

[root@nccztsjb-node-15 kafka-34991]# bin/kafka-topics.sh --bootstrap-server 122.120.45.214:34991 --describe --topic testtop01
Topic: testtop01        TopicId: EKABL7twT-CP9WL51Mjjmw PartitionCount: 3       ReplicationFactor: 1    Configs: segment.bytes=1073741824,max.message.bytes=10485760,retention.bytes=32212254720
        Topic: testtop01        Partition: 0    Leader: 1       Replicas: 1     Isr: 1
        Topic: testtop01        Partition: 1    Leader: 1       Replicas: 1     Isr: 1
        Topic: testtop01        Partition: 2    Leader: 1       Replicas: 1     Isr: 1
