kafka streams vs spark

Use a dataflow-like model to handle windowing problems with scrambled data Distributed processing, and has a fault-tolerant mechanism, can be quickly implemented failover There is the ability to re-process the data, so when your code changes, you can recalculate the output. There is no time to roll the deployment. For those who want to skip the preface and want to read the document directly, you can go directly to Kafka

There is a simple demo of spark-streaming, and there are examples of Kafka successful running, where the combination of both, is also commonly used one. 1. Related component versionFirst confirm the version, because it is different from the previous version, so it is necessary to record, and still do not use Scala, using Java8,spark 2.0.0,

1. Join for different time slice data streams After the first experience, I looked at Spark WebUi's log and found that because spark streaming needed to run every second to calculate the data in real time, the program had to read HDFs every second to get the data for the inner join. Sparkstreaming would have cached the data it was processing to reduce IO and incr

Kafka is a distributed publish-subscribe messaging system, which is simply a message queue, and the benefit is that the data is persisted to disk (the focus of this article is not to introduce Kafka, not much to say). Kafka usage scenarios are still relatively large, such as buffer queues between asynchronous systems, and in many scenarios we will design as follo

, that is, successive processing of multiple messages for the same data stream partition. Samza's execution and data flow modules are pluggable, although SAMZA is characterized by yarn that relies on Hadoop (another resource scheduler) and Apache Kafka. Comparison of three types of frames: What's in common:All three of these real-time computing systems are open-source distributed, with low latency, scalability, and fault tolerance, all o
