@Rocky when will be the expected release date of 4.2 version for starrocks kubernetes

Based on the current StarRocks release roadmap and historical versioning patterns as of October 2026, here is the expected status for StarRocks 4.2: Expected Release Date While an exact date for StarRocks 4.2 has not been officially announced, it is expected to be released in late 2026 (likely between late October and December). This is based on the following: * Minor Version Cadence: StarRocks typically aims for a minor version release (e.g., 4.0 to 4.1 to 4.2) approximately every four months. * Version 4.1 Timeline: StarRocks 4.1 was released in May 2026. Following the 4-month cycle, version 4.2 was projected for a September/October 2026 release. * Current Status: As of mid-October 2026, version 4.1 is still receiving active maintenance patches (v4.1.6 was released on September 30, 2026), suggesting that the 4.2 release is likely imminent or scheduled for the coming weeks. StarRocks on Kubernetes For Kubernetes deployments (via the StarRocks Operator or Helm Charts): * Operator Versioning: The StarRocks Kubernetes Operator follows its own versioning (currently in the v1.11.x range) and does not have a "version 4.2." * Engine Version: The Operator generally adds support for new minor engine versions (like 4.2) shortly after the core engine is released. You can usually deploy the latest engine version by updating the

tag in your

StarRocksCluster

CRD once the Docker images are available. Anticipated Changes in 4.2 Pre-release documentation and community discussions suggest that StarRocks 4.2 will include: * Extended VARCHAR limits: Increasing the maximum length for VARCHAR columns up to 2 GiB. * Improved Kubernetes recovery: Further refinements to the "FE In-Place Recovery" and "Cluster Snapshot" features introduced in earlier 3.x and 4.x versions to enhance disaster recovery on K8s. For the most up-to-date announcement, you should monitor the StarRocks GitHub Releases page or the official StarRocks Slack community.

@Rocky what is the current latest version and what is the java version for 4.2

As of mid-October 2026, the current status of StarRocks versions and the Java requirements for the upcoming 4.2 release are as follows: Current Latest Version The current latest stable version of StarRocks is v4.1.6, which was released on September 30, 2026. This version includes various performance enhancements, bug fixes, and behavior changes, such as: * Networking: The default AWS SDK HTTP client has been switched back to the SDK's native client (Poco is now opt-in). * Memory Management: Jemalloc's dedicated oversize arena is now enabled by default to reduce fragmentation in BE and CN nodes. * Adaptive Layout: Further refinements to the adaptive tablet management features introduced in the 4.1 branch. Java Version for StarRocks 4.2 For the upcoming StarRocks 4.2 release, the Java baseline is expected to be upgraded: * Required Version: JDK 21 LTS. * Context: There is a formal proposal to move the Java baseline from JDK 17 to JDK 21 for the 4.2 release to provide a longer support window and leverage newer JVM features. * Comparison: * StarRocks 3.5 to 4.1: Requires JDK 17 or later. * StarRocks 4.2 (Expected): Will require JDK 21 LTS as the minimum supported version for the Frontend (FE) and Java-dependent features (like Java UDFs and JNI-based connectors). If you are planning to upgrade to 4.2 once it is released, you should prepare your environment by ensuring JDK 21 is installed on all nodes where Java components are running.

@Rocky is there release date for starrocks 4.2 with java 21

As of November 3, 2026, there is no officially announced specific day for the StarRocks 4.2 release, but it is expected to arrive in late 2026 (likely November or December). Here is the current status regarding the release and its Java 21 requirement: Expected Release Date * Cadence: StarRocks typically follows a release cycle of one minor version every four months. * Timeline: StarRocks 4.1 was released in May 2026. Following the standard 4-month cadence, version 4.2 was initially anticipated around September/October 2026. * Current Status: As of late October 2026, the community is still releasing maintenance patches for the 4.1 branch (v4.1.7 was released on October 26, 2026). This suggests that version 4.2 is in the final stages of stabilization and its release is likely imminent. Java 21 Requirement It is confirmed through official community proposals (such as Issue #74519) that StarRocks 4.2 will upgrade the Java baseline to JDK 21 LTS. * Minimum Version: JDK 21 will become the minimum supported version for the Frontend (FE), Java-extensions, and the build/CI environment. * Reasoning: This move is intended to align with the long-term support window of JDK 21 (which extends to late 2029) and to allow the engine to eventually leverage newer JVM features like Virtual Threads (JEP 444). * Preparation: If you plan to upgrade to 4.2, you should ensure your environment is ready for JDK 21, as older versions like JDK 17 will no longer be supported for the 4.2 core components.
