Supported Versions and Interoperability for Confluent Platform¶
This topic provides the supported version and interoperability information for Confluent Platform and its components for Confluent Platform 7.7 and older. Note that older versions are removed as their support windows end. If a newer Confluent Platform version exists, you can select it in the version picker in the lower left to view its interoperability and version support.
Confluent Platform and Apache Kafka compatibility¶
Important
Change Notice: Effective with Confluent Platform 8.0, Confluent Platform, Community version will transition to follow the Kafka release cycle more closely. The Kafka community provides about one year of patch support for a Kafka version, from the minor version release date, and Confluent Community software will soon follow a similar support schedule. Confluent customers using Confluent Enterprise will continue to receive patch updates for three years following minor version release.
| Confluent Platform | Apache Kafka® | Release Date | Standard End of Support | Platinum End of Support |
|---|---|---|---|---|
| 7.7.x | 3.7.x | July 26, 2024 | July 26, 2026 | July 26, 2027 |
| 7.6.x | 3.6.x | February 9, 2024 | February 9, 2026 | February 9, 2027 |
| 7.5.x | 3.5.x | August 25, 2023 | August 25, 2025 | August 25, 2026 |
| 7.4.x | 3.4.x | May 3, 2023 | May 3, 2025 | May 3, 2026 |
| 7.3.x | 3.3.x | November 4, 2022 | November 4, 2024 | November 4, 2025 |
| 7.2.x | 3.2.x | July 6, 2022 | July 6, 2024 | July 6, 2025 |
| 7.1.x | 3.1.x | April 5, 2022 | April 5, 2024 | April 5, 2025 |
| 7.0.x | 3.0.x | October 27, 2021 | October 27, 2023 | October 27, 2024 |
Note the following about Confluent Platform versions and support levels:
Standard support means any support level below Platinum support. For example, if you have Gold support, you have Standard support.
The end of support date applies to minor versions and any maintenance versions that come after the minor version. This means that maintenance versions follow the same two year lifecycle of the minor version. For example, standard support for Confluent Platform 7.0.x ends on October 27, 2023.
The two year support policy is standard. End of support is extended one year for Platinum support agreements.
Platinum tier support is not offered for Confluent for Kubernetes (CFK).
Starting with CFK 2.9, the standard support policy of CFK is for 2 years from the first patch release (
.0) date.You can apply your Confluent Platform Platinum tier support contract to the Confluent Platform components deployed by CFK when both of the following conditions are true:
- You are on a currently supported version of CFK.
- The Confluent Platform version you want to use is compatible with a currently supported version of CFK.
For the CFK-specific support policy and supportability between CFK and Confluent Platform versions, see Supported versions of Confluent Platform and CFK.
Each version of Confluent Platform includes several component services which are only compatible in that specific Confluent Platform version. There are exceptions, including clients and Confluent Control Center, which can be used across versions. All services included in Confluent Platform are supported, including Apache Kafka® and its subcomponents: Kafka brokers, Apache ZooKeeper™, Java and Scala clients, Kafka Streams, and Kafka Connect.
Preview releases¶
Features designated with “preview” status in this documentation are not intended for production use. They should only be used for evaluation and non-production testing purposes or to provide feedback to Confluent.
Confluent encourages customers to submit questions and suggestions about preview features using the Confluent Support Portal.
Preview features are not “Supported Software” under Confluent’s support policies.
Additionally, Confluent may make changes to preview user experience and APIs before they are released for production use.
Operating systems¶
Confluent Platform and clients support these operating systems.
It is recommended that you run Confluent Platform across uniform OS, Confluent Platform, and JAVA versions.
Confluent Platform supports both X86 and ARM64 hardware architecture. ARM64 is supported in Confluent Platform 7.6.0 and later. For more information on required hardware, see Hardware.
| Operating System | 7.7.x | 7.6.x | 7.5.x | 7.4.x | 7.3.x | 7.2.x | 7.1.x | 7.0.x |

- Deprecated
- Support for these OS versions is deprecated because they have reached their end of life. You should not use a deprecated OS in a production deployment. Confluent Platform 7.7 may run on a deprecated OS, but this may change in a future release.
Additional notes about OS support:
- SELinux
Confluent Platform is supported on Amazon Linux, Debian, Oracle Linux, RHEL, CentOS, Debian, Rocky Linux and Ubuntu Operating Systems.
Confluent is not accountable for Security-Enhanced Linux (SELinux) policy development, support, or enforcement. If you experience issues running Confluent Platform with SELinux enabled on a supported Linux Operating System, contact your OS provider for assistance.
- Windows
Windows is not currently supported for Confluent Platform.
Windows 8.1 and later, as well as Windows 2016 and later, are supported by the C/C++ and .NET clients.
- macOS
- macOS 10.14 and later is supported for testing and development purposes only.
- File descriptors
- For the file descriptor requirement for Kafka, see File Descriptors and mmap.
- ulimit
Control Center requires many open RocksDB files. Set the
ulimitfor the number of open files to a minimum value of 16384 using theulimit -ncommand.For the other Confluent Platform components, specifically Schema Registry and Replicator, you can leave the
ulimitas the OS default.- RHEL with TLS
When installing Confluent Platform on RHEL8 with TLS encryption, you must add DH Key Size JVM Parameters for each component. For more information, see Strong crypto defaults in RHEL 8 and deprecation of weak crypto algorithms.
Set the following component-level environment variables to the argument:
- Control Center:
CONTROL_CENTER_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - Schema Registry:
SCHEMA_REGISTRY_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - Kafka, ZooKeeper, and Connect:
KAFKA_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - REST Proxy:
KAFKAREST_OPTS=-Djdk.tls.ephemeralDHKeySize=2048 - ksqlDB:
KSQL_OPTS=-Djdk.tls.ephemeralDHKeySize=2048
- Control Center:
- atime
The
atimemount option impacts performance, because every read operation on a file system causes a write operation.Confluent recommends disabling the tracking of
atimeby setting thenoatimeoption when you mount Kafka data disks.
Java¶
You need to separately install the correct version of Java before you start the Confluent Platform installation process.
The following table lists Java support in Confluent Platform by version. Note the following:
- You should use the full JDK to help Confluent Support with troubleshooting and to provide better support if you experience issues with Confluent Platform.
- OpenJDK, Zulu OpenJDK, Eclipse Temurin (formerly known as AdoptOpenJDK), and Oracle are supported with Confluent Platform.
- Docker images support version 11 or 17. For more information, see Docker.
| Confluent Platform | Recommended | Supported |
|---|---|---|
| 7.7.x | 17 | 17, 11, 8 * |
| 7.6.x | 17 | 17, 11, 8 * |
| 7.5.x | 17 | 17, 11, 8 * |
