Apache Avro 是一种高效的数据序列化系统用于在不同的应用程序和平台之间传输和存储数据。它提供了一种紧凑且高效的二进制数据编码格式相比其他常见的序列化方式Avro能够实现更快的序列化和更小的数据存储。
而Confluent Schema Registry是由Confluent公司提供的一个开源组件旨在解决分布式系统中的数据模式演化和兼容性的问题。它是建立在Apache Avro之上的一个服务可以用于集中管理和存储Avro数据的模式Schema确保分布式系统中的数据一致性和兼容性。它广泛应用于事件流处理平台如Kafka为数据流的可靠性和互操作性提供了支持。
2 搭建Schema Registry
2.1 下载Confluent并解压
curl -O https://packages.confluent.io/archive/7.4/confluent-community-7.4.3.tar.gz
sudo tar xvf confluent-community-7.4.3.tar.gz -C /usr/local/bin2.2 设置环境变量
vim ~/.bashrc添加 export SCHEMA_REG_HOME/usr/local/bin/confluent-7.4.3 export PAHT$PAHT:${SCHEMA_REG_HOME}/bin source ~/.bashrc2.3 修改配置
获取本机IP
ip addr修改配置文件
