Recommendations
Tair (Enterprise Edition) is a high-availability, high-performance distributed NoSQL database service. Tair offers instance series based on DRAM, NVM, and Enterprise SSDs (ESSDs), providing low-latency access, data persistence, and lower overall costs. Tair also delivers enhanced data structures and flexible storage methods for a wide range of scenarios. For more information, see Overview.
-
DRAM-based instances: use a multi-threading model and deliver read/write performance approximately three times that of same-spec Redis Open-Source Edition instances. DRAM-based instances also provide enhanced data modules, allowing you to focus on application development without worrying about storage structures and timeliness.
-
Persistent memory-optimized instances: use persistent memory to provide large-capacity, Redis-compatible in-memory databases that persist each operation without relying on traditional disk storage. Compared with Redis Open-Source Edition instances, persistent memory-optimized instances reduce costs by up to 30% while delivering comparable throughput and latency, improving business data reliability.
-
ESSD/SSD-based instances: store data on ESSDs or standard SSDs and are compatible with the core data structures and APIs of open source Redis. These instances deliver large-capacity, low-cost, persistent database services while improving data reliability and reducing the reserved memory required for open source Redis forks.
