July 14, 2025

This release introduces a shared‑storage single‑replica deployment mode that significantly reduces overall instance costs. In addition, we have enhanced instance operations, data development, and data migration features and coverage.

Shared‑storage single‑replica deployment

The shared‑storage single‑replica deployment mode is now generally available. In this mode, each instance maintains only a single full‑featured replica while still supporting cross‑zone disaster recovery. This release currently supports the Tencent Cloud self‑operated channel.

The RTO (Recovery Time Objective) of this mode is at the minute level, which is slightly higher than the RTO < 8 seconds offered by the multi‑replica deployment mode, but it significantly reduces both compute and storage costs. Compared with the Shared Nothing Architecture, the Shared Storage Architecture also enables faster scaling.

The shared‑storage single‑replica deployment mode is ideal for scenarios such as testing and learning, workloads with low business continuity or high‑availability requirements, and non‑critical workloads focused on cost reduction.

Instance operations

• Added support for creating pay‑as‑you‑go cluster instances via Open API, covering the self‑operated channels and the Alibaba Cloud Marketplace channel.

• Binlog monitoring is now supported for analytical instances.

• When an account is overdue, instances in the recycle bin are automatically deleted to prevent additional charges.

Data development

• On the domestic site of OceanBase Cloud, SQL Console and Data Import now support Baidu Cloud.

• On the domestic site of OceanBase Cloud, Data Archiving and Data Cleanup now support AWS China.

Data migration

• On the domestic site of OceanBase Cloud, Data Migration now supports the AWS cloud provider.

Users can set IOPS upper and lower limits, configure resource group weights, and implement more flexible strategies for balancing resource contention. Default background task resource isolation policies are provided to prevent background tasks from competing with business IOPS.

• Proactive operations and fault self-healing:

  • New proactive operations events feature supports proactive operations event notifications, enabling users to respond and manage them uniformly.

  • New in-platform messaging feature allows users to receive proactive operations event notifications.

  • New fault self-healing feature (allowlist access) can automatically recover from business anomalies, reducing fault response time and ensuring service continuity.

• Instance recycle bin supports instance recovery:

  • Enhanced instance recycle bin capabilities now support instance recovery based on backup data stored in the recycle bin, with support for querying recovery history records. This completes the cycle from instance deletion and backup storage to instance recovery.

• Feature extensions:

  • Custom alert templates now support webhook channels.

  • Database proxy introduces maximum connection management, allowing users to configure appropriate maximum connection numbers based on business needs.

Enhanced database security capabilities

• Database account security: Extended database password character range and optimized complexity rule display, improving password management flexibility.
