kafka使用文件存储消息,这就直接决定kafka在性能上严重依赖文件系统的本身特性.且无论任何OS下,对文件系统本身的优化几乎没有可能.文件缓存/直接内存映射等是常用的手段.因为kafka是对日志文件进行append操作,因此磁盘检索的开支是较小的;同时为了减少磁盘写入的次数,broker会将消息暂时buffer起来,当消息的个数(或尺寸)...

Kafka Scalability Distributing a Topic’s partitions across many Brokers allows the Topic to scale well beyond any single host. One cluster of Kafka Brokers can host multiple topics, allowing you to scale several unique data streams. Developers can specify the number of partitions in each topic, ...
Because traces are distributed across different services, this process of tagging spans and correlating them is called “distributed tracing”. How distributed tracing works Distributed tracing tracks a request when it travels across different services in a microservices architecture. While doing so, it ...
Kafka Schema Registry is the centrally managed, enforced data format registry that enforces the format, or schema, of the data produced and consumed in an Apache Kafka ecosystem. It supports Avro, JSON, and Protobuf schemas, ensuring compatibility in sending Kafka topics from different producers ...
