You must tell Control Center about the REST endpoints for all brokers in your cluster,
and the advertised listeners for the other components you may want to run. Without
these configurations, the brokers exponential function python and components will not show up on Control Center. Start with the file you updated in the previous sections with regard to replication factors and enabling Self-Balancing Clusters.

integration is seamless – if you are already using Kafka with Avro data, using
Schema Registry only requires including the serializers with your
application and changing one setting. Tiered Storage provides options for storing large volumes of Kafka data
using your favorite cloud provider, thereby reducing operational burden and cost. With Tiered Storage, you can keep data on cost-effective object storage, and
scale brokers only when you need more compute resources. Cluster Linking directly connects clusters together and mirrors topics
from one cluster to another over a link bridge. Cluster Linking simplifies
setup of multi-datacenter, multi-cluster, and hybrid cloud deployments. If the Control Center mode is not explicitly set,
Confluent Control Center defaults to Normal mode.

  1. Confluent Platform is a full-scale data streaming platform that enables you to easily access,
    store, and manage data as continuous, real-time streams.
  2. It is the de facto technology developers and architects use to build the newest generation of scalable, real-time data streaming applications.
  3. Connect seems deceptively simple on its surface, but it is in fact a complex distributed system and plugin ecosystem in its own right.
  4. The following image provides an example of a Kafka environment without Confluent Control Center and a similar
    environment that has Confluent Control Center running.

Go above & beyond Kafka with all the essential tools for a complete data streaming platform. Scale Kafka clusters up to a thousand brokers, trillions of messages per day, petabytes of data, hundreds of thousands of partitions. Reduced infrastructure mode means that no metrics and/or monitoring data is visible in Control Center and
internal topics to store monitoring data are not created. Because of this, the resource burden of running Control Center is lower in Reduced infrastructure mode.

To learn more about KRaft, see KRaft Overview and Kraft mode
under Configure Confluent Platform for production. Born in Silicon Valley, data in motion is becoming a foundational part of modern companies. Confluent’s cloud-native platform is designed to unleash real-time data. It acts as a central nervous system in companies, letting them connect all their applications around real-time streams and react and respond intelligently to everything that happens in their business. Data streaming enables businesses to continuously process their data in real time for improved workflows, more automation, and superior, digital customer experiences. Confluent helps you operationalize and scale all your data streaming projects so you never lose focus on your core business.

The following image shows an example of Control Center running in Normal mode. This may not sound so significant now, but we’ll see later on that keys are crucial for how Kafka deals with things like parallelization and data locality. Values are typically the serialized representation of an application domain object or some form of raw message input, like the output of a sensor. « These Confluent capabilities are a big help to us, because instead of having to roll our own, we can simply take advantage of what Confluent has built on top of the open-source platform. »

And when ready to deploy, the platform creates a significant ongoing operational burden — one that only grows over time. Build lightweight, elastic applications and microservices that respond immediately to events and that scale during live operations. Process, join, and analyze streams and tables of data in real-time, 24×7. Available locally or fully-managed via Apache Kafka on Confluent Cloud. For KRaft, the examples show an isolated mode configuration for a multi-broker cluster managed by a single controller. This maps to the deprecated ZooKeeper configuration, which uses one ZooKeeper and multiple brokers in a single cluster.

In the context of Apache Kafka, a streaming data pipeline means ingesting the data from sources into Kafka as it’s created and then streaming that data from Kafka to one or more targets. An abstraction of a distributed commit log commonly found in distributed databases, Apache Kafka provides durable storage. Kafka can act as a ‘source of truth’, being able to distribute data across multiple nodes for a highly available deployment within a single data center or across multiple availability zones. Build a data-rich view of their actions and preferences to engage with them in the most meaningful ways—personalizing their experiences, across every channel in real time. The librdkafka library is the C/C++ implementation of the Kafka protocol, containing both Producer and Consumer
support. It was designed with message delivery, reliability and high performance in mind.

Monitoring services and Normal mode¶

Control Center includes the following pages where you can drill down to view data and
configure features in your Kafka environment. The following table lists Control Center pages and what they display depending on the mode for Confluent Control Center. Management services are provided in both Normal and Reduced infrastructure mode. By default Control Center operates in Normal mode, meaning both management and monitoring features are enabled. Kafka Connect, the Confluent Schema Registry, Kafka Streams, and ksqlDB are examples of this kind of infrastructure code.

Kafka Connect

The simplicity of the log and the immutability of the contents in it are key to Kafka’s success as a critical component in modern data infrastructure—but they are only the beginning. An event is any type of action, incident, or change that’s identified or recorded by software or applications. For example, a payment, a website click, or a temperature reading, along with a description of what happened.

The users topic is created on the Kafka cluster and is available for use
by producers and consumers. This quick start gets you up and running with Confluent Cloud using a
Basic Kafka cluster. The first section shows how to use Confluent Cloud to create
topics, and produce and consume data to and from the cluster. The second section walks you through how to add
ksqlDB to the cluster and perform queries on the data using a SQL-like syntax. Kafka provides high throughput event delivery, and when combined with open-source technologies such as Druid can form a powerful Streaming Analytics Manager (SAM). Druid consumes streaming data from Kafka to enable analytical queries.

If you don’t plan to complete Section 2 and
you’re ready to quit the Quick Start, delete the resources you created
to avoid unexpected charges to your account. Depending on the chosen cloud provider and other settings, it may take a few
minutes to provision your cluster, but after the cluster has provisioned,
the Cluster Overview page displays. Unlock greater agility and faster innovation with loosely coupled microservices. Use Confluent to completely decouple your microservices, standardize on inter-service communication, and eliminate the need to maintain independent data states. It can read and write
Avro data, registering and looking up schemas in Schema Registry. Because it
automatically translates JSON data to and from Avro, you can get all the
benefits of centralized schema management from any language using only HTTP and

One of the primary advantages of Kafka Connect is its large ecosystem of connectors. Writing the code that moves data to a cloud blob store, or writes to Elasticsearch, or inserts records into a relational database is code that is unlikely to vary from one business to the next. Likewise, reading from a relational database, Salesforce, or a legacy HDFS filesystem is the same operation no matter what sort of application does it. You can definitely write this code, but spending your time doing that doesn’t add any kind of unique value to your customers or make your business more uniquely competitive.

For developers who want to get familiar with the platform, you can start with the Quick Start for Confluent Platform. This quick start shows you how to run Confluent Platform using Docker on a single broker, single cluster
development environment with topic replication factors set to 1. Commonly used to build real-time streaming data pipelines and real-time streaming applications, today, there are hundreds of Kafka use cases. Any company that relies on, or works with data can find numerous benefits.


Confluent products are built on the open-source software framework of Kafka to provide customers with
reliable ways to stream data in real time. Confluent provides the features and
know-how that enhance your ability to reliably stream data. If you’re already using Kafka, that means
Confluent products support any producer or consumer code you’ve already written with the Kafka Java libraries. Whether you’re already using Kafka or just getting started with streaming data, Confluent provides
features not found in Kafka. This includes non-Java libraries for client development and server processes
that help you stream data more efficiently in a production environment, like Confluent Schema Registry,
ksqlDB, and Confluent Hub.
