Confluent Cloud includes different types of server processes for steaming data in a production environment. In addition to brokersand topics, Confluent Cloud provides implementations of Kafka Connect, Schema Registry, and ksqlDB. Explore how you can process data in-flight to create high-quality, reusable streams delivered anywhere in real-time.

Build your proof of concept on our fully managed, cloud-native service for Apache Kafka®. When you are finished with the Quick Start, delete the resources you createdto avoid unexpected charges to your account. In this step, you run a Flink SQL statement to hide personal information inthe users stream and publish the scrubbed data to a new Kafka topic, namedusers_mask. You can produce example data to your Kafka cluster by using thehosted Datagen Source Connector for Confluent Cloud.

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. Bring real-time, contextual, highly governed and trustworthy data to your AI systems and applications, just in time, and deliver production-scale AI-powered applications faster. Embrace the cloud at your pace and maintain a persistent data bridge to keep data across all on-prem, hybrid and multicloud environments in sync.

  1. Confluent makes Kafka enterprise ready and provides customers with the complete set of tools they need to build apps quickly, reliably, and securely.
  2. Performing real-time computations on event streams is a core competency of Kafka.
  3. Connect your data in real time with a platform that spans from on-prem to cloud and across clouds.
  4. If your stream processing application goes down, its state goes with it, unless you’ve devised a scheme to persist that state somewhere.

This topic describesKafka use cases, the relationship between Confluent and Kafka, and key differences betweenthe Confluent products. Each Confluent Platform release includes the latest release of Kafka and additional tools and services that make iteasier to build and manage an event streaming platform. An data streaming platform would not be complete without the ability to process and analyze data as soon as it’s generated.

Confluent Platform¶

Many ofthe commercial Confluent Platform features are built into the brokers as afunction of Confluent Server. “Our transformation to a cloud-native, agile company required a large-scale migration from open source Apache Kafka. With Confluent, we now support real-time data sharing across all of our environments, and see a clear path forward for our hybrid cloud roadmap.” Connect your data in real time with a platform that spans from on-prem to cloud and across clouds.

Confluent Platform provides all of Kafka’s open-source features plus additional proprietary components.Following is a summary of Kafka features. For an overview ofKafka use cases, features and terminology, see Kafka Introduction. Likewise on the consume side, if a consumer reads a message that has an incompatible schema from the version the consumer code expects, Schema Registry will tell it not to consume the message. Schema Registry doesn’t fully automate the problem of schema evolution—that is a challenge in any system regardless of the tooling—but it does make a difficult problem much easier by keeping runtime failures from happening when possible. Kafka Connect, the Confluent Schema Registry, Kafka Streams, and ksqlDB are examples of this kind of infrastructure code.

The (KRaft) and (ZooKeeper) files that ships with Confluent Platform have replication factors setto 1 on several system topics to support development test environments and Quick Start for Confluent Platform scenarios. For real-world scenarios, however, a replicationfactor greater than 1 is preferable to support fail-over and auto-balancing capabilities on both system and user-created topics. Kafka provides high throughput event delivery, and when combined with open-source technologies such as Druid can form a powerful Streaming Analytics Manager (SAM). Events are first loaded in Kafka, where they are buffered in Kafka brokers before they are consumed by Druid real-time workers. Scale Kafka clusters up to a thousand brokers, trillions of messages per day, petabytes of data, hundreds of thousands of partitions. Today, Kafka is used by over 80% of the Fortune 100 across virtually every industry, for countless use cases big and small.

Apache Kafka is an open-source distributed streaming system used for stream processing, real-time data pipelines, and data integration at scale. Originally created to handle real-time data feeds at LinkedIn in 2011, Kafka quickly evolved from messaging queue to a full-fledged event streaming platform capable of handling over 1 million messages per second, or trillions of messages per day. Apache Kafka® is an open-source, distributed, event streaming platform capable of handlinglarge volumes of real-time data. You use Kafka to build real-time streaming applications.Confluent is a commercial, global corporation that specializes in providing businesseswith real-time access to data. Confluent was founded by the creators of Kafka, and itsproduct line includes proprietary products based on open-source Kafka.

Its job is to maintain a database of all of the schemas that have been written into topics in the cluster for which it is responsible. That “database” is persisted in an internal Kafka topic and cached in the Schema Registry for low-latency access. Schema Registry can be run in a redundant, high-availability configuration, so it remains up if one instance fails. Kafka can connect to nearly any other data source in traditional enterprise information systems, modern databases, or in the cloud. It forms an efficient point of integration with built-in data connectors, without hiding logic or routing inside brittle, centralized infrastructure.

However they are deployed, they are independent machines each running the Kafka broker process. Each broker hosts some set of partitions and handles incoming requests to write new events to those partitions or read events from them. Apache Kafka consists of a storage layer and a compute layer top growth stocks for march 2021 that combines efficient, real-time data ingestion, streaming data pipelines, and storage across distributed systems. In short, this enables simplified, data streaming between Kafka and external systems, so you can easily manage real-time data and scale within any type of infrastructure.

To Maximize Kafka, You Need Confluent

Self-managing open source Kafka comes with many costs that consume valuable resources and tech spend. Take the Confluent Cost Savings Challenge to see how you can reduce your costs of running Kafka with the data streaming platform loved by developers and trusted by enterprises. In order to make complete sense of what Kafka does, we’ll delve into what an event streaming platform is and how it works. So before delving into Kafka architecture or its core components, let’s discuss what an event is.

Step 2: Run Flink SQL statements¶

This will help explain how Kafka stores events, how to get events in and out of the system, and how to analyze event streams. “Confluent Cloud made it possible for us to meet our tight launch deadline with limited resources. With event streaming as a managed service, we had no costly hires to maintain our clusters and no worries about 24×7 reliability.” Once applications are busily producing messages to Kafka and consuming messages from it, two things will happen. These are brand new applications—perhaps written by the team that wrote the original producer of the messages, perhaps by another team—and will need to understand the format of the messages in the topic. Order objects gain a new status field, usernames split into first and last name from full name, and so on.

Quick Start for Confluent Cloud¶

Confluent’s cloud-native, complete, and fully managed service goes above & beyond Kafka so your best people can focus on what they do best – delivering value to your business. 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. Connect seems deceptively simple on its surface, but it is in fact a complex distributed system and plugin ecosystem in its own right. And if that plugin ecosystem happens not to have what you need, the open-source Connect framework makes it simple to build your own connector and inherit all the scalability and fault tolerance properties Connect offers. All of these are examples of Kafka connectors available in the Confluent Hub, a curated collection of connectors of all sorts and most importantly, all licenses and levels of support. Connect Hub lets you search for source and sink connectors of all kinds and clearly shows the license of each connector.

This allows Kafka to guarantee that messages having the same key always land in the same partition, and therefore are always in order. Partitioning takes the single topic log and breaks it into multiple logs, each of which can live on a separate node in the Kafka cluster. This way, the work of storing messages, writing new messages, and processing existing messages can be split among many nodes in the cluster. Since Kafka topics are logs, there is nothing inherently temporary about the data in them. Every topic can be configured to expire data after it has reached a certain age (or the topic overall has reached a certain size), from as short as seconds to as long as years or even to retain messages indefinitely. When you write an event to a topic, it is as durable as it would be if you had written it to any database you ever trusted.
