Benefits
Full Compatibility with Redis and Instance Upgrade Without Downtime
Tair is fully compatible with Redis. Migration to and from both databases can be performed out-of-the-box without any code modifications. Additionally, Tair is bundled with a variety of extended data structures that can simplify data storage and development complexity. The configuration change feature of ApsaraDB for Redis Community Edition can be used to upgrade an ApsaraDB for Redis instance to a Tair instance without downtime. View Details
Data Persistence
Tair persistent memory-optimized instances use persistent memory and support command-level real-time persistence, semi-synchronization, and data restoration to a specific point in time. This instance series provides 90% read and write capabilities of ApsaraDB for Redis Community Edition at only 70% of the cost. This makes the instance series an ideal choice to replace solutions that use open source Redis for caching and ApsaraDB RDS for persistent storage. This way, the simplified database system ensures data consistency between caching and persistent data storage. View Details
Data Restoration to a Specific Point in Time
Tair provides the data flashback feature that can restore data to a specific point in time, accurate to the second. This feature enables you to restore an entire instance or specific keys to a new instance or the current instance of a specific point in time. This fine-grained data restoration capability prevents data loss caused by accidental operations and ensures data security. View Details
Global Distributed Cache and Data Synchronization
Global Distributed Cache is an in-house active geo-redundancy database system. The cloud-native geo-replication capability of Tair supports data synchronization across up to three regions. This helps you implement geo-redundancy, disaster recovery, data consistency across regions, and nearby access with reduced latency. View Details
Multiple Extended Data Structures
Tair provides a wide range of built-in extended data structures on top of the support for all open source Redis data structures. These extended data structures accelerate development timelines and improve code security by sparing you large amounts of code and the use of Lua scripts. Additionally, these data structures enable you to implement high-performance distributed locks, multidimensional leaderboards, sliding windows, and JSON file storage with ease. View Details

Multiple Architectures: Standalone, Master-replica, Read/Write Splitting, and Cluster
Standalone for caching-only scenarios, master-replica for automatic failover, read/write splitting for read-intensive scenarios, and cluster for capacity-sensitive scenarios
Standalone Architecture
Designed for caching-only scenarios and scales out smoothly to deliver cost-effective, high QPS performance.
Master-replica Architecture
Provides a master node and a replica node for real-time data synchronization. Automatic failover completes within seconds, and is completely transparent, ensuring the availability of your applications.
Cluster Architecture
Adopts a distributed architecture in which each shard contains a master node and a replica node to implement automatic failover and ensure high availability, provides multiple specifications, and supports push-button scaling.
Read/Write Splitting Architecture
Designed for read-dominant scenarios with a maximum of 100,000 writes per second and 600,000 reads per second to break bottlenecks of hotkey reads.
Enterprise-level Capabilities: Global Distributed Cache, Data Flashback, and Multiple Data Structures
Enterprise-level features for fast implementation in various scenarios
Data Restoration to a Specific Point in Time
Allows you to restore data to a specific point in time within the last seven days by second to prevent data loss caused by accidental operations and improve data security. View Details
Real-time Data Persistence
Implements data persistence without dependence on append-only files (AOF) and Redis Database (RDB) files to prevent data loss from power outages and enhance data reliability. View Details
Global Distributed Cache
Supports real-time read and write synchronization across zones and regions, provides cross-region replication, and achieves geo-redundancy, disaster recovery, and nearby access with reduced latency. View Details
Automatic Scale-up
Handles traffic spikes and prevents out-of-memory errors to ensure business stability.
