Alibaba Cloud releases minor versions of ApsaraDB for Redis from time to time to implement new features, fix known issues, and improve user experience. This topic describes the release notes for minor versions of ApsaraDB for Redis Enhanced Edition (Tair). We recommend that you update minor versions of instances during off-peak hours.
View or update the minor version of an instance
You can view the current minor version of an instance in the ApsaraDB for Redis console. For more information about update operations and usage notes, see Update the minor version.

- The system automatically detects the minor version of an instance. If the instance is of the latest minor version, the Minor Version Upgrade button is not displayed or is dimmed.
- Minor version updates may differ from region to region. The minor version of an instance displayed in the ApsaraDB for Redis console prevails.
ApsaraDB for Redis Enhanced Edition (Tair)
The rapid development of the Internet makes business scenarios more diverse and complicated. ApsaraDB for Redis Enhanced Edition (Tair) is a high-availability and high-performance NoSQL database service. It provides several series of instances based on storage media such as dynamic random-access memory (DRAM), non-volatile memory (NVM), and ESSDs to meet your requirements for low-latency access, persistence, and reduced overall costs. Tair provides higher performance, more data structures, and more flexible storage methods to meet your requirements in a variety of scenarios. For more information about ESSDs, see ESSDs.
- Tair DRAM-based instances that are compatible with Redis 6.0: Redis 6.2 and earlier. In addition, this instance series supports the extended data structures of Tair.
- Tair DRAM-based instances that are compatible with Redis 5.0: Redis 5.0 and earlier. In addition, this instance series supports the extended data structures of Tair.
- Tair Persistent memory-optimized instances: Redis 6.0 and earlier. This instance series has limits on specific commands. For more information, see Limits on commands supported by Tair instances.
- Tair ESSD-based instances: Redis 4.0 and earlier. This instance series has limits on specific commands. For more information, see Limits on commands supported by Tair instances.
Series | Description |

DRAM-based instances |
|
Persistent memory-optimized instances |
|
ESSD-based instances | ESSD-based instances are developed based on ESSDs and are compatible with core data structures and APIs of open source Redis. These instances can provide large-capacity, low-cost, and persistent database services. ESSD-based instances reduce costs and improve data reliability. In addition, ESSD-based instances reduce the amount of memory that is reserved for the forks of native Redis databases. This series type is suitable for scenarios that store warm and cold data, and require compatibility with open source Redis, large capacity, and high access performance. |
Hybrid-storage instances (phased out) | Hybrid-storage instances store data in both memory and disks. During off-peak hours, hybrid-storage instances can separate hot data from cold data to ensure a high memory access speed and provide a larger storage than ApsaraDB for Redis Community Edition instances. This allows hybrid-storage instances to balance performance with costs. Note Hybrid-storage instances are phrased out. For more information, see End-of-Sale for ApsaraDB for Redis hybrid-storage instances. We recommend that you choose Persistent memory-optimized instances. If you have purchased a hybrid-storage instance, you can submit a ticket to migrate the data of the instance. |
