Bulk access to topics, consumer groups or transactional ids with a prefix can now be granted using a single rule. Access control for topic creation has also been improved to enable access to be granted to create specific topics or topics with a prefix.
Host name verification is now enabled by default for SSL connections to ensure that the default SSL configuration is not susceptible to man-in-the-middle attacks. You can disable this verification if required. You can now dynamically update SSL truststores without broker restart.
With this new feature, you can store sensitive password configs in encrypted form in ZooKeeper rather than in cleartext in the broker properties file. The replication protocol has been improved to avoid log divergence between leader and follower during fast leader failover.
We have also improved resilience of brokers by reducing the memory footprint of message down-conversions. By using message chunking, both memory usage and memory reference time have been reduced to avoid OutOfMemory errors in brokers. Kafka clients are now notified of throttling before any throttling is applied when quotas are enabled.
This enables clients to distinguish between network errors and large throttle times when quotas are exceeded. We have added a configuration option for Kafka consumer to avoid indefinite blocking in the consumer. We have dropped support for Java 7 and removed the previously deprecated Scala producer and consumer. Kafka Connect includes a number of improvements and features. KIP enables you to control how errors in connectors, transformations and converters are handled by enabling automatic retries and controlling the number of errors that are tolerated before the connector is stopped.
More contextual information can be included in the logs to help diagnose problems and problematic messages consumed by sink connectors can be sent to a dead letter queue rather than forcing the connector to stop.
KIP adds a new extension point to move secrets out of connector configurations and integrate with any external key management system. The placeholders in connector configurations are only resolved before sending the configuration to the connector, ensuring that secrets are stored and managed securely in your preferred key management system and not exposed over the REST APIs or in log files.
Scala users can have less boilerplate in their code, notably regarding Serdes with new implicit Serdes. Message headers are now supported in the Kafka Streams Processor API, allowing users to add and manipulate headers read from the source topics and propagate them to the sink topics. Windowed aggregations performance in Kafka Streams has been largely improved sometimes by an order of magnitude thanks to the new single-key-fetch API. We have further improved unit testibility of Kafka Streams with the kafka-streams-testutil artifact.
Here is a summary of some notable changes: Kafka 1. ZooKeeper session expiration edge cases have also been fixed as part of this effort. Controller improvements also enable more partitions to be supported on a single cluster. KIP introduced incremental fetch requests, providing more efficient replication when the number of partitions is large. Some of the broker configuration options like SSL keystores can now be updated dynamically without restarting the broker.
See KIP for details and the full list of dynamic configs. Delegation token based authentication KIP has been added to Kafka brokers to support large number of clients without overloading Kerberos KDCs or other authentication servers. Additionally, the default maximum heap size for Connect workers was increased to 2GB. Several improvements have been added to the Kafka Streams API, including reducing repartition topic partitions footprint, customizable error handling for produce failures and enhanced resilience to broker unavailability.
See KIPs , , , and for details. Here is a summary of a few of them: Since its introduction in version 0. For more on streams, check out the Apache Kafka Streams documentation, including some helpful new tutorial videos.
These are too many to summarize without becoming tedious, but Connect metrics have been significantly improved KIP , a litany of new health check metrics are now exposed KIP , and we now have a global topic and partition count KIP Over-the-wire encryption will be faster now, which will keep Kafka fast and compute costs low when encryption is enabled. Previously, some authentication error conditions were indistinguishable from broker failures and were not logged in a clear way.
This is cleaner now. Use the following command to startup ZooKeeper:. By default, ZooKeeper will generate a number of log statements at start-up as shown below. One of the log entries will mention 'binding to port 0.
This indicates that ZooKeeper was successfully started. Open the Kafka releases page which contains the latest binary downloads. Kafka is written in Scala , which is a programming language that has full support for functional programming. Scala source code is intended to be compiled to Java bytecode so that the resulting executable code runs on a Java virtual machine. This only matters if you are using Scala yourself.
If not the case, go ahead and choose the highest supported version. Extract the gzipped TAR file, downloaded in the previous step. Use following command to startup Kafka:. When starting, Kafka will generate a number of log statements as shown below. The last log entries will mention '[Kafka Server 01], started'. This means that a Kafka instance is up and running.

This blog post was originally published on the Confluent blog. Is Windows your favorite development environment? The Windows Subsystem for Linux 2 makes it all possible. In the 'Windows specifications' section, find the 'OS build. If not, you need to update Windows Turn on the Windows Subsystem for Linux feature before installing a Linux distribution. Open PowerShell as an administrator, and run the following command:.
Download the Linux kernel update package , which is a regular Windows Installer. Double-click the. WSL 2 is ready to use. This blog post uses Ubuntu Select Ubuntu When the installation is complete, click Launch.
The shell opens and displays the following message:. Run the package manager to get the latest updates. In the Ubuntu shell window that opened above, run the following commands:. Kafka requires the Java runtime to be version 8 or higher. Check the Java version in your Linux installation:.
There are a lot of ways to install Java. On Ubuntu, this is one of the simplest:. You can install Kafka by using a package manager, or you can download the tarball and extract it to your local machine directly. Select a mirror from the Kafka download site and download the tarball. The following command downloads Apache Kafka version 2.
Run the following commands to untar the Kafka archive, and cd to the kafka directory:. There will be a lot of output, and ZooKeeper will be ready in a short time, typically around a second or two. Open another terminal session. Change the directory to the kafka directory, and start the Kafka broker:. If you arrange the windows to be side-by-side, your output should resemble the following screenshot:. Open another terminal session and run the kafka-topics command to create a Kafka topic named quickstart-events :.
Arrange the producer and consumer terminal windows to be side by side. In the producer terminal, type a few more messages, and watch as they appear in the consumer terminal. Superficially, this appears to work, but there are limitations: Kafka uses specific features of POSIX to achieve high performance, so emulations—which happen on WSL 1—are insufficient.
For example, the broker will crash when it rolls a segment file. Another approach that works well is to run Kafka in Docker containers. You may recall a time when Linux was anathema to Microsoft. Even File Explorer was integrated nicely with the Linux file system. The second means that WSL 1 consumes a lot of resources.
WSL 1 was not sufficient to run Kafka reliably. Now the path is clear for devs to build Kafka and ksqlDB apps on Windows. Published at DZone with permission of Jim Galasyn.
