Then get a iterator and call the next method to get the next element and construct a new Messageandmetadata instance to return 3. Clearcurrentchunk: Clears the current data block, that is, the

kafkaproducer class. This class consists of partitioner, metadata, recordaccumulator, sender, and metrics. Partitioner is a class used to calculate the part of a message. As the name suggests, metadata stores the metadata of the Kafka cluster. The updates of metadata are related to topics. The recordaccumulator is similar to a queue. All messages sent by the producer are sent to the queue for processing. The sender class uses NiO to send and receive

on the subject or content. The Publish/Subscribe feature makes the coupling between sender and receiver looser, the sender does not have to care about the destination address of the receiver, and the receiver does not have to care about the sending address of the message, but simply sends and receives the message based on the subject of the message. Cluster (Cluster): To simplify system configuration in point-to-point communication mode, MQ provides a Cluster (cluster) solution. A cluster is

The main design objectives are as follows: Provides message persistence in a time-complexity O (1) manner, guaranteeing constant-time complexity of access performance even for terabytes or more data High throughput rates. Capable of single-machine support for transmission of messages up to 100K p

-round. 3 Implementing the Architecture A schema implementation architecture is shown in the following figure: Analysis of 3.1 producer layer The service assumptions within the PAAs platform are deployed within the Docker container, so in order to meet the non-functional requirements, another process is responsible for collecting logs and therefore does not invade the service framework and processes. Using flume ng for log collection, this open source component is very powerful, can be seen

Introduced Kafka is a distributed, partitioned, replicable messaging system. It provides the functionality of a common messaging system, but has its own unique design. What does this unique design look like? Let's first look at a few basic messaging system terms: Kafka the message to topic as a unit.• The program that will release the message to Kafka topic

Kafka is a distributed streaming platform, what exactly does it mean. The streaming platform has the following three main functions:☆ Publish and subscribe stream records, similar to Message Queuing or enterprise-level messaging systems.☆ You store stream records in a fault-tolerant manner.☆ Timely processing when the flow record is generated. Kafka is used in two major categories of applications:☆ Establis
