2025
This page lists the new features, optimizations, and bug fixes for AnalyticDB for PostgreSQL Serverless Pro instances released in 2025.
To apply the latest changes to your instance, update to the latest minor engine version in the AnalyticDB for PostgreSQL console. For instructions, see Update the minor version of an instance.
December 2025 (V7.1.0.4)
New features
Feature | Description | Reference |
Virtual Warehouse (VW) [Disabled by default] | Enables single-write and multiple-read operations, isolating compute resources so multiple services can run read/write splitting and parallel processing independently. Create or revoke a VW in minutes, and scale up or down, start or stop, or upgrade a VW at any time to match workload demands and reduce resource usage and costs. Multiple VWs share the same data without replication, preventing data redundancy and ensuring consistency. Backup and recovery are supported for O&M. To enable this feature, submit a ticket to request access. |
Bug fixes and optimizations
Area | Description |
Storage node | Fixes a stability issue that occurred when storage nodes performed OID rollbacks. |
Backup and recovery | Fixes a stability issue caused by incorrect status checks for backup points. |
Master node | Fixes a memory leak on the master node. |
December 2025 (V7.1.0.3)
Bug fixes
Area | Description |
High availability | Fixes stability issues during database restarts and upgrades to enhance high availability. |
November 2025 (V7.1.0.2)
Bug fixes
Area | Description |
Beam | Fixes a stability issue with the local file cache for Beam column-oriented tables. |
Beam | Fixes a stability issue in the Beam write path. |
ORCA optimizer | Fixes a stability issue in the ORCA optimizer. |
September 2025 (V7.1.0.1)
New features
Feature | Description |
Local File Cache [Disabled by default] | Caches hot spot data from storage nodes to local disks, improving access performance for row-store heap tables and indexes. Most effective when the shared buffer hit rate is low and query performance has degraded, because it reduces remote read overhead and improves access latency. Requires reserved local disk space. No database restart is required after enabling. To enable this feature, submit a ticket to request access. |
Optimizations
Area | Description |
Beam table DDL performance | Improves index creation performance on |
Storage compression | Changes the default compression type for Beam to |
Real-time write performance | Optimizes I/O for the stats collector to improve real-time write performance for Beam. |
| Significantly improves the execution performance of |
