topic-partition是kafka分布式的精华, 也是针对kafka进行生产或消费的最小单元;在这篇里我们开始介绍相关的数据结构内容如下:rd_kafka_topic_partition_trd_kafka_topic_partition_list_trd_kafka_toppar_srd_kafk…
一、安装librdkafka 二、开启kafka相关服务 2.1、启动zookeeper 2.2、启动Kafka 2.3、创建topic 三、c语言操作kafka的范例 3.1、消费者 3.2、生产者 3.3、生产者和消费者的交互 总结 一、安装librdkafka git clone https://github.com/edenhill/librdkafka.git cd librdkafka git checkout v1.7.0 ./configure...

具体来说，有一个名为rd_kafka_topic_partition_trd_kafka_topic_partition_list_trd_kafka_toppar_s的结构体，用于存放待获取的具体partition信息。当需要某个特定partition，但尚未从broker获取其详细信息时，这个partition即为desired partition。在rd_kafka_itopic_t中，有一个名为rkt_desp的list，专门...
Kafka集群的每一台Broker都会缓存整个集群的Meta Data,当Broker或某一个Topic的Meta Data信息发生变化时, Kafka集群的Controller都会感知到作相应的状态转换,同时把发生变化的新Meta Data信息广播到所有的Broker。 RdKafka对Meta Data的封装和操作包括Meta Data获取、定时刷新以及引用的操作,如Partition Leader迁移,Partition...

My partition logic selection: like for each message (its unique ID % 50) , and then calling Kafka producer API to route a specific message to a particular topic partition . RdKafka::ErrorCode resp = m_kafkaProducer->produce(m_kafkaTopic,(unique ID % 50),RdKafka::Producer::RK_MSG_COPY...
