Release notes​

1.9​

1.9.1​

Improvements

  • [Helm Chart] The operator will not create PersistentVolumeClaim (PVC) for log storage when logStorageSize is set to 0. #398
  • [Operator] The operator can detect whether the values of mountPath and name in storageVolumes are duplicated. An error is returned when duplicate values exist. #388
  • [Operator] The number of FE nodes cannot be scaled down to 1. #394
  • [Operator] The values of the feEnvVars, beEnvVars and cnEnvVars fields in multiple values YAML files can be merged. #396
  • [Operator] Add spec.containers.securityContext.capabilities in the StarRocksCluster CRD to customize the Linux capabilities of containers. #404

Bug Fixes

Fixed the following issues:

  • [Operator] The annotations field in service can be updated. #402 #399
  • [Operator] The modification of statefulset and deployment is patched instead of updated. It solves the problem that upgrading CN will cause all CN pods to be terminated and restarted when CN and HPA are enabled. #397
  • [Operator] The modification of service object is patched instead of updated. It prevents the operator from overwriting the modification, for example, when a Kubernetes Cloud provider is used and the service object is modified by that Kubernetes Cloud provider. #387

1.9.0​

New features

  • Add StarRocksWarehouse CRD to support StarRocks Warehouse. Note that StarRocks Warehouse is currently a feature of the StarRocks Enterprise Edition. #323

Enhancements

  • Add the status.reason field in StarRocksCluster CRD. When the apply operation of a subcontroller fails during cluster deployment, you can execute kubectl get starrockscluster <name_of_the_starrocks_cluster_object> -oyaml, and view error logs shown in status.reason field in the returned result. #359
  • An empty directory can be mounted in the storageVolumes field. #324

Bug Fixes

Fixed the following issues:

  • The status of the StarRocks cluster was inconsistent with the status of the cluster's FE, BE and CN components. #380
  • The HPA resource is not deleted when autoScalingPolicy is deleted. #379
  • The HPA resource is not removed when starRocksCnSpec is deleted. #357

1.8​

1.8.8​

Bugfixes

  • [Operator] The operator no longer annotates on search service (which is an internal service) when annotations are added by using StarRocksFeSpec.service, StarRocksBeSpec.service, and StarRocksCnSpec.service. #370

1.8.7​

Enhancements

  • Add the livenessProbeFailureSeconds and readinessProbeFailureSeconds fields in StarRocksCluster CRD. When StarRocks is under heavy workload and the time of liveness and readiness probes still use default values, the liveness and readiness probes may fail and cause the containers to restart. In this case, you can add larger values to these two fields. #309

1.8.6​

Bug Fixes

Fixed the following issue:

  • An error sendfile() failed (32: Broken pipe) while sending request to upstream is returned during a Stream Load job. After Nginx sends the request body to FE, the FE then redirects the request to the BE. At this point, the data cached in Nginx may already be lost. #303

Doc

1.8.5​

Improvements

  • [Helm Chart] The annotations and labels can be customized for the service account of the operator: The Operator creates a service account named starrocks by default, and users can customize the annotations and labels for the service account starrocks of the operator by specifying the annotations and labels fields in serviceAccount in values.yaml. The operator.global.rbac.serviceAccountName field is deprecated. #291
  • [Operator] FE service supports explicit protocol selection for Istio: When Istio is installed in the Kubernetes environment, Istio needs to determine the protocol of the traffic from the StarRocks cluster, in order to provide additional functionality such as routing and rich metrics. So FE service explicitly defines its protocol as MySQL in the appProtocol field. This improvement is particularly important because the MySQL protocol is a server-first protocol that is incompatible with automatic protocol detection and sometimes may incur connection failures. #288

Bug Fixes

Fixed the following issue:

  • [Helm Chart] The root user's password in StarRocks may not be initialized successfully when starrocks.initPassword.enabled is true and the value of starrocks.starrocksCluster.name is specified. It is caused by the wrong FE service domain name used by the initpwd pod to connect FE service. More specifically, in this scenario, FE service domain name uses the value specified in starrocks.starrocksCluster.name, while the initpwd pod still uses the value of the starrocks.nameOverride field to form the FE service domain name. (#292)

Upgrade notes

  • [Helm Chart] When the value specified in starrocks.starrocksCluster.name is different from the value of starrocks.nameOverride, the old configmaps for FE, BE, and CN will be deleted. New configmaps with new names for the FE, BE, and CN will be created. This may result in the restart of the FE, BE, and CN pods.

1.8.4​

Features

  • [Helm Chart] The metrics of StarRocks clusters can be monitored by using the Prometheus and ServiceMonitor CR. For the user guide, see Integration with Prometheus and Grafana. #284
  • [Helm Chart] Add the storagespec and more fields in starrocksCnSpec in values.yaml to configure the log volume for CN nodes in a StarRocks Cluster. #280
  • Add the terminationGracePeriodSeconds in the StarRocksCluster CRD to configure how long to wait before forcefully terminating a pod when a StarRocksCluster resource is being deleted or updated. #283
  • Add the startupProbeFailureSeconds field in the StarRocksCluster CRD to configure the startup probe failure threshold for the pods in the StarRocksCluster resource. #271

Bug Fixes

Fixed the following issue:

  • The FE Proxy cannot handle STREAM LOAD requests correctly when multiple FE pods exist in the StarRocks cluster. #269

Doc

1.8.3​

Upgrade notes

  • [Helm Chart] Add JAVA_OPTS_FOR_JDK_11 to the default fe.conf file. When the default fe.conf file is used and the helm chart is upgraded to v1.8.3, FE pods may restart. #257

Features

  • [Helm Chart] Add the watchNamespace field to specify the one and only namespace that the operator needs to watch. Otherwise, the operator watches all namespaces in the Kubernetes cluster. In most cases, you do not need to use this feature. You can use this feature when the Kubernetes cluster manages too many nodes, the operator watches all namespaces and consumes too many memory resources. #261
  • [Helm Chart] Add the Ports field in starrocksFeProxySpec in the values.yaml file to allow users to specify the NodePort of FE Proxy service. #258

Improvements

  • The value of the proxy_read_timeout parameter is changed in the nginx.conf file to 600s from 60s, in order to avoid timeout.

1.8.2​

Improvements

  • Increase the maximum memory usage allowed for the operator pods to avoid OOM. #254

1.8.1​

Features

Improvements

  • Remove the related Kubernetes resources when the BeSpec or CnSpec of the StarRocks cluster is deleted, ensuring a clean and consistent state of the cluster. #245

1.8.0​

Upgrade notes and behavior changes

  • [Operator] To upgrade the StarRocksCluster CRD and operator you need to manually apply the new StarRocksCluster CRD starrocks.com_starrocksclusters.yaml and operator.yaml.

  • [Helm Chart]

    • To upgrade the Helm Chart, you need to perform the following:

      1. Use the values migration tool to adjust the format of the previous values.yaml file to the new format. The values migration tool for different operating systems can be downloaded from the Assets section. You can get help information of this tool by running the migrate-chart-value --help command. #206

        migrate-chart-value --input values.yaml --target-version v1.8.0 --output ./values-v1.8.0.yaml

      2. Update the Helm Chart repo.

        helm repo update

      3. Execute the helm upgrade command to apply the adjusted values.yaml file to the StarRocks helm chart kube-starrocks.

        helm upgrade <release-name> starrocks/kube-starrocks -f values-v1.8.0.yaml

    • Two subcharts, operator and starrocks, are added into the kube-starrocks helm chart. You can choose to install StarRocks operator or StarRocks cluster respectively by specifying the corresponding subchart. This way, you can manage StarRocks clusters more flexibly, such as deploying one StarRocks operator and multiple StarRocks clusters.

Features

  • [Helm Chart] Multiple StarRocks clusters in a Kubernetes cluster. Support deploying multiple StarRocks clusters in different namespaces in a Kubernetes cluster by installing the starrocks Helm subchart. #199
  • [Helm Chart] Support to configure the initial password of StarRocks cluster's root users when executing the helm install command. Note that, the helm upgrade command does not support this feature.
  • [Helm Chart] Integration with Datadog: Integrated with Datadog to collect StarRocks clusters' metrics and logs. To enable this feature, you need to configure the Datadog related fields in the values.yaml file. For the detailed user guide, see Integration with Datadog. #197 #208
  • [Operator] Run pods as a non-root user. Add the runAsNonRoot field to allow pods to run as non-root users, which can enhance security. #195
  • [Operator] FE proxy. Add the FE proxy to allow external clients and data load tools that support Stream Load protocol to access StarRocks clusters in Kubernetes. This way, you can use the load job based on Stream Load to load data into StarRocks clusters in Kubernetes. #211

Improvements

  • Add the subpath field in StarRocksCluster CRD. #212
  • Increase the disk size allowed for the FE metadata. The FE container stops running when the available disk space that can be provisioned to store the FE metadata is less than that default value. #210
