Guide to using correct startup commands for Kafka cluster deployment
How to correctly use the Kafka startup command for cluster deployment
Kafka is a distributed stream processing platform that can handle large amounts of real-time data. It can be used to build a variety of applications such as real-time data analysis, machine learning, and fraud detection.
To deploy a Kafka cluster, you need to install Kafka software on each server. Then you need to configure each server so that they can communicate with each other. Finally, you need to start the cluster.
Install Kafka software
You can download the Kafka software from the Apache Kafka website. Once the download is complete, you'll need to unzip it into a directory on each server.
Configuring Kafka Server
To configure the Kafka server, you need to edit the config/server.properties
file. This file contains various settings such as:
-
broker.id
: A unique ID for each server. -
listeners
: The port the server listens on. -
log.dirs
: The directory where Kafka logs are stored. -
zookeeper.connect
: The address of the ZooKeeper cluster.
Start Kafka Cluster
To start the Kafka cluster, you need to run the following command on each server:
kafka-server-start config/server.properties
This will start Kafka server. You can run the following command on each server to verify that the server is running:
kafka-server-info
This will display status information for the server.
Create a topic
To create a topic you need to run the following command:
kafka-topics --create --topic my-topic --partitions 3 --replication-factor 2
This will create a topic named "my-topic" , the topic has 3 partitions and 2 replicas.
Producing data
To produce data to the topic you need to run the following command:
kafka-console-producer --topic my-topic
This will open a console where you can Enter the data to be sent to the topic.
Consuming Data
To consume data from a topic you need to run the following command:
kafka-console-consumer --topic my-topic --from-beginning
This will open a console where you can View the data in the topic.
Manage cluster
You can use the following command to manage the Kafka cluster:
-
kafka-topics
: management theme. -
kafka-partitions
: Management partitions. -
kafka-replicas
: Manage replicas. -
kafka-consumers
: Manage consumers. -
kafka-producers
: Manage producers.
Troubleshooting
If you are having trouble using Kafka, you can check out the following resources:
- Apache Kafka Documentation: https://kafka.apache.org/documentation/
- Kafka User Forum: https://groups.google.com/g/kafka-users
- Kafka JIRA: https: //issues.apache.org/jira/projects/KAFKA

Generative artificial intelligence is affecting or expected to affect many industries, and the time for supply chain network transformation is ripe. Generative AI promises to significantly facilitate real-time interactions and information in the supply chain, from planning to procurement, manufacturing and fulfillment. The impact on productivity of all these processes is significant. A new study from Accenture calculates that all working hours of end-to-end supply chain activities of more than 40% of enterprises (43%) may be affected by production artificial intelligence. In addition, 29% of the working time in the entire supply chain can be automated through production AI, while 14% of the working time in the entire supply chain can be significantly increased through production AI. This emerging technology has the potential to impact the entire supply chain, from design and planning, to sourcing and manufacturing, to fulfillment.

MongoDB is a non-relational database that has been widely used in many large enterprises. Compared with traditional relational databases, MongoDB has excellent flexibility and scalability. This article will delve into the deployment and capacity planning of MongoDB clusters to help readers better understand and apply MongoDB. 1. The concept of MongoDB cluster MongoDB cluster is composed of multiple MongoDB instances. The instance can be a single MongoDB process running on different machines.

Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.

MongoDB is a document-based, distributed database suitable for storing large data sets, managing unstructured data, application development, real-time analytics, and cloud storage with flexibility, scalability, high performance, ease of use, and Community support and other advantages.
