Kafka command line tool collection: Help you easily manage message queues

Kafka is a distributed publish-subscribe messaging system that can process A lot of data flow. The Kafka command line tool can help you easily manage Kafka clusters, including creating and managing topics, producing and consuming messages, and monitoring the status of the cluster.

1. Create and manage topics

kafka-topics --create --topic my-topic --partitions 3 --replication-factor 2

This command will create a topic named "my-topic" with 3 partitions and 2 replication factors.

kafka-topics --list

This command will list all topics.

kafka-topics --describe --topic my-topic

This command will describe the details of the topic "my-topic".

2. Producing and consuming messages

kafka-console-producer --topic my-topic

This command will start a console producer that you can use to send messages to the topic "my-topic".

kafka-console-consumer --topic my-topic --from-beginning

This command will start a console consumer that you can use to consume messages from the topic "my-topic".

3. Monitor cluster status

kafka-server-status --url localhost:9092

This command will display the status information of the Kafka server.

kafka-broker-stats --url localhost:9092

This command will display the statistics of the Kafka broker.

kafka-consumer-groups --list --url localhost:9092

This command will list all consumer groups.

4. Other commands

kafka-admin --help

This command will display help information for all Kafka management commands.

kafka-run-class org.apache.kafka.tools.MirrorMaker --help

This command will display the help information of the MirrorMaker tool.

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

Discuss situations where writing platform-specific code in Java might be necessary.Discuss situations where writing platform-specific code in Java might be necessary.Apr 25, 2025 am 12:22 AM

Reasons for writing platform-specific code in Java include access to specific operating system features, interacting with specific hardware, and optimizing performance. 1) Use JNA or JNI to access the Windows registry; 2) Interact with Linux-specific hardware drivers through JNI; 3) Use Metal to optimize gaming performance on macOS through JNI. Nevertheless, writing platform-specific code can affect the portability of the code, increase complexity, and potentially pose performance overhead and security risks.

Java will further enhance platform independence through cloud-native applications, multi-platform deployment and cross-language interoperability. 1) Cloud native applications will use GraalVM and Quarkus to increase startup speed. 2) Java will be extended to embedded devices, mobile devices and quantum computers. 3) Through GraalVM, Java will seamlessly integrate with languages ​​such as Python and JavaScript to enhance cross-language interoperability.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
