This article details Zhihu's security anti‑fraud system challenges with its self‑managed MongoDB cluster, the strategic move to Alibaba Cloud MongoDB services, the step‑by‑step migration plan, and the operational and performance benefits achieved after the successful cloud transition.
This guide walks through accessing a production TiDB cluster via pod IP, Service ClusterIP, or DNS, initializing users and databases, and performing scaling and version upgrades by editing the cluster's YAML configuration in Kubernetes.
This guide walks you through the complete process of setting up a production‑grade TiDB 8.4.0 cluster on a self‑managed Kubernetes environment using the latest TiDB Operator, covering environment prerequisites, PV pool initialization, operator installation, CRD creation, and full cluster deployment with detailed commands and configurations.
OceanBase’s open‑source ecosystem—spanning data migration tools, developer utilities, a database proxy, and robust operational management—delivers comprehensive, open, and compatible support that enhances development, migration, and maintenance, positioning it as a competitive enterprise‑grade distributed relational database.
OceanBase employs a shared‑nothing distributed cluster design where each node runs its own SQL, storage, and transaction engines, evolving through versions 0.5 to 4.0 to improve scalability, high availability, and low latency, while supporting multi‑tenant deployments and TPC‑C benchmark success.
This guide details the upgrade procedures, prerequisites, and impact considerations for OceanBase, OBproxy, OCP, and OB‑DashBoard across Kubernetes and bare‑metal environments, providing step‑by‑step commands, dashboard actions, and DBA precautions to ensure a smooth transition.
This guide walks you through upgrading the ob‑operator, creating S3 credentials, configuring an OBTenantBackupPolicy YAML, applying the backup, and verifying the backup status to achieve a full data backup of an OceanBase 4.2.5 tenant to Baidu Cloud BOS using Kubernetes.
This guide walks you through deploying OceanBase OBProxy and the OceanBase Dashboard on a Kubernetes cluster using yaml manifests, a setup script, and Helm, covering environment requirements, configuration details, verification steps, and access instructions.
This guide walks you through installing the OB‑Operator, preparing Kubernetes prerequisites, deploying the operator and an OceanBase cluster, and verifying the deployment, providing practical commands and configuration examples for a production‑ready setup.
This guide details three online TiDB migration scenarios—including placement‑rule replica placement, TiCDC with BR backup, and hybrid strategies—covering preparation, network and resource requirements, configuration commands, region balancing, PD leader transfer, and post‑migration cleanup for seamless cross‑data‑center database relocation.
