Tair is an in-memory database service based on ApsaraDB for Redis Community Edition and brings enterprise-level features and multiple storage media with cost-effectiveness.
DRAM-based instance: delivers ultra-high throughput and triples the performance of open source Redis, which is suitable for industries such as livestreaming, e-commerce, and online education.
Persistent memory-optimized instance: implements real-time data persistence at 70% the cost of ApsaraDB for Redis Community Edition, which is an ideal choice for the gaming industry.
ESSD-based instance: provides storage capacities of up to hundreds of terabytes, which is suitable for the storage of large amounts of warm and cold data with high performance.
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
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
