Streaming data is the continuous flow of real-time information, and can be used in modern applications to enable data processing, storage, and analysis.
Multiple data flows.Data streaming is beneficial in situations where a continuous flow of data from multiple data pipelines must be processed into useful output. By bringing together data from various applications, streamed data can provide a variety of outputs based on user requirements. System visi...
Apache Kafka is an open-source, distributed, Java/Scala event streaming platform for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications. Kafka events are organized and durably stored in topics. Kafka was originally developed at LinkedIn. It has fiv...
At first, streaming processing deals with data streams. A data stream is a constant flow of data, which updates with high frequency and loses its relevance in a short period of time. For example, these could be transactional data, information from IoT devices, hardware sensors, etc. Stream ...

The role of open source technology such as Kafka, Mesos, ElasticSearch, and modern software engineering such as Docker and Micro Services in architecting a data stream platform Streaming use cases from experiences with customers in the field
以Kafka、Storm 为代表的流计算框架用于实时计算, 而Spark 或 MapReduce 则负责每天、每小时的数据批处理。 在ETL 等场合,这样的设计常常导致同样的计算逻辑被实现两次,耗费人力不说,保证一致性也是个问题。 Spark Streaming 基于 Spark,另辟蹊径提出了 D-Stream(Discretized Streams)方案:将流数据切成很小的批(micr...
Kafka is usually used to build real-time data streaming pipelines and data streaming applications that adapt to data streams What is Exactly Once Semantics? The computers that comprise a distributed publish-subscribe messaging system can always fail independently of one another. In the case of Kafka...
Develop real-time streaming applications that allow you to react to or transform data streams In general, you can use Kafka for website activity tracking, stream processing, log aggregation, CEP, metrics collection and monitoring, real-time analytics, ingesting data into Hadoop or Spark, replaying...
