, Memoryrecoverchannel, FileChannel. Memorychannel can achieve high-speed throughput, but cannot guarantee the integrity of the data. Memoryrecoverchannel has been built to replace the official documentation with FileChannel. FileChannel guarantees the integrity and consistency of the data. When configuring FileChannel specifically, it is recommended that the directory and program log files that you set up FileChannel be saved to a different disk for increased efficiency.Sink when setting up sto

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 Streams D

Kafka topic offset requirements Brief: during development, we often consider it necessary to modify the offset of a consumer instance for a certain topic of kafka. How to modify it? Why is it feasible? In fact, it is very easy. Sometimes we only need to think about it in another way. If I implement kafka consumers myself, how can I let our consumer code control t
-throughput Distributed messaging system) 1.3 Kafka now The Apache Kafka is a distributed, Push-subscribe-based messaging system that features fast, extensible, and durable. It is now an open source system owned by Apache and is widely used by various commercial companies as part of the Hadoop ecosystem. Its greatest feature is the ability to process large amounts of data in real time to meet a variety of
, 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

Kafka instead of log aggregation ). Log aggregation generally collects log files from the server and stores them in a centralized location (File Server or HDFS) for processing. However, Kafka ignores the file details and abstracts them into a log or event message stream. This reduces the processing latency of Kafka and makes it easier to support multiple data so

Before we introduce why we use Kafka, it is necessary to understand what Kafka is. 1. What is Kafka. Kafka, a distributed messaging system developed by LinkedIn, is written in Scala and is widely used for horizontal scaling and high throughput rates.
