We then divide the number of partitions by the total number of consumer streams (threads) to determine the number of partitions to assign to each consumer. If it does not evenly divide, then the first few consumers will have one extra partition.DEFAULT:rangeSource Kafka再平衡机制详解 1)...
Currently a replica only has two possible states, follower or leader. And it is identified by the 3-tuple (topic, partition, broker). This works for the current implementation because there can be at most one such replica on a broker. However, now we can have two such replicas on a bro...
The following picture from the Kafka documentation describes the situation with multiple partitions of a single topic. Server 1 holds partitions 0 and 3 and server 2 holds partitions 1 and 2. We have two consumer groups, A and B. A is made up of two consumers and B is made up of four...
A log for a topic named "my_topic" with two partitions consists of two directories (namelyand) populated with data files containing the messages for that topic. The format of the log files is a sequence of "log entries""; each log entry is a 4 byte integerNstoring the message length w...
From the file, ports in use by kafka and zookeeper services can be identified. There should be java processes listening at these ports. a) Check the kafka port listed in the server.properties file with the netstat command, port 9092. ...
/** * Find the topic partitions that have change based on the replica given. * * The changes identified are: * 1. topic partitions for which the broker is not a replica anymore * 2. topic partitions for which the broker is now the leader * 3. topic partitions for which the broker ...
For a table without a primary key, if you selectPartitions are identified by the hash values of the primary key, topics are synchronized to different partitions based on the hash value of the database_name.schema.table_name. Partitions are differentiated by the hash values of database_name.sc...
Inconclusion, Kafka topics are a crucial component of the Apache Kafka ecosystem. They provide a way to organize and store related events and messages in a durable and scalable manner. Kafka topics are identified by their unique names and can be partitioned into one or more partitions, which ...
