You can verify your download by following these procedures and using these KEYS. Kafka 3. For more information, please read the detailed Release Notes. Here is a summary of some notable changes:. Kafka 2. Kafka 1. The Apache Kafka Project Management Committee has packed a number of valuable enhancements into the release.

Here is a summary of a few of them:. You can download releases previous to 0. Download 3. The current stable version is 3. This only matters if you are using Scala and you want a version built for the same Scala version you use. Otherwise any version should work 2. Here is a summary of some notable changes: log4j 1. Here is a summary of some notable changes: The deprecation of support for Java 8 and Scala 2. Here is a summary of some notable changes: TLSv1.

Here is a summary of some notable changes: TLS 1. Here is a summary of some notable changes: Allow consumers to fetch from closest replica. Support for incremental cooperative rebalancing to the consumer rebalance protocol.

MirrorMaker 2. New Java authorizer Interface. Support for non-key joining in KTable. Administrative API for replica reassignment. Kafka Connect now supports incremental cooperative rebalancing. Kafka Streams now supports an in-memory session store and window store. The AdminClient now allows users to determine what operations they are authorized to perform on topics. There is a new broker start time metric.

We now track partitions which are under their min ISR count. Consumers can now opt-out of automatic topic creation, even when it is enabled on the broker. Kafka components can now use external configuration stores KIP We have implemented improved replica fetcher behavior when errors are encountered.

Here is a summary of some notable changes: Java 11 support Support for Zstandard, which achieves compression comparable to gzip with higher compression and especially decompression speeds KIP Avoid expiring committed offsets for active consumer group KIP Provide Intuitive User Timeouts in The Producer KIP Kafka’s replication protocol now supports improved fencing of zombies.

Previously, under certain rare conditions, if a broker became partitioned from Zookeeper but not the rest of the cluster, then the logs of replicated partitions could diverge and cause data loss in the worst case KIP Here is a summary of some notable changes: KIP adds support for prefixed ACLs, simplifying access control management in large secure deployments. 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. Kafka can now tolerate disk failures better. With KIP, Kafka now handles disk failure more gracefully.

A single disk failure in a JBOD broker will not bring the entire broker down; rather, the broker will continue serving any log files that remain on functioning disks. Since release 0. As anyone who has written or tested a wire protocol can attest, this put an upper bound on throughput.

Thanks to KAFKA, this can now be as large as five, relaxing the throughput constraint quite a bit. These different versions only matter if you are using Scala and you want a version built for the same Scala version you use.

Setting Up and Running Apache Kafka on Windows – Goavega – Kafka Producer :


Apache Kafka is a distributed streaming platform. Kafka is used for building real-time data pipelines and streaming apps. Kafka can be used to publish and subscribe to stream of records, similar to a message queue or enterprise messaging system.

Kafka can be run on both Linux and Windows. First thing that you need to do is download Kafka. Latest version is Kafka 2. Once you have downloaded the zip folder, all you need to do is extract it. Inside the bin folder, you will find a separate Windows folder which will have the executable file for Windows. To do a basic check you can have 2 terminals open and you can have producer and consumer running separately. Any message you type on the producer window would appear on the consumer window in real time like below.

Before testing the Java code for Producer and Consumer, make sure to have a Kafka clients jar added to your build path. Any recent jar should ideally work. More partitions allow greater parallelism for consumption, but this will also result in more files across the brokers. This value is recommended to be increased for installations with data dirs located in RAID array. The following configurations control the flush of data to disk. There are a few important trade-offs here: 1. Durability: Unflushed data may be lost if you are not using replication.

Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks. The settings below allow one to configure the flush policy to flush data after a period of time or every N messages or both. This can be done globally and overridden on a per-topic basis. The number of messages to accept before forcing a flush of data to disk log.

The policy can be set to delete segments after a period of time, or after a given size has accumulated. Deletion always happens from the end of the log. The minimum age of a log file to be eligible for deletion due to age log. Segments are pruned from the log unless the remaining segments drop below log. Functions independently of log. When this size is reached a new log segment will be created.

This is a comma separated host:port pairs, each corresponding to a zk server. You can also append an optional chroot string to the urls to specify the root directory for all kafka znodes. The rebalance will be further delayed by the value of group. The default value for this is 3 seconds.

We override this to 0 here as it makes for a better out-of-the-box experience for development and testing. However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
