kafka中如何创建topic？

通过如下的命令创建topic

kafka-topics.sh \
    --bootstrap-server <Kafka集群地址> \
    --create \
    --topic <Topic名称> \
    --partitions <分区数> \
    --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

 

 

创建之后，通过以下的命令查看创建好的topic

[root@nccztsjb-node-15 kafka-34991]# bin/kafka-topics.sh --bootstrap-server 122.120.45.214:34991 --describe --topic testtop01
