Alibaba Cloud releases minor versions of ApsaraDB for Redis from time to time to provide more 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 proxy nodes that belong to 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 does not exist 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.
Introduction to 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 cost. 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.
Series type | Description |
---|---|
Performance-enhanced instances |
|
Persistent memory-optimized instances | Persistent memory-optimized instances adopt Intel Optane DC persistent memory to provide you with in-memory databases that have a large capacity and are compatible with open source Redis. A persistent memory-optimized instance persists each operation and does not use disks to implement data persistence. Compared with an ApsaraDB for Redis Community Edition instance, it reduces costs by up to 30% and delivers almost the same throughput and latency. This helps improve the reliability of business data. |
Storage-optimized instances | Storage-optimized instances were 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. Storage-optimized instances reduce costs and improve data reliability. In addition, storage-optimized instances reduce the amount of reserved memory that is required for the forks of open source Redis. This series type applies to 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 strike a balance between performance
and cost.
Note Hybrid-storage instances are discontinued. For more information, see Sales of ApsaraDB for Redis hybrid-storage instances are discontinued. We recommend that you use performance-enhanced instances that provide higher performance and more features.
If you have purchased s hybrid-storage instance, you can submit a ticket to migrate the data of the instance. |
