Recommendations
Tair (Enterprise Edition) is a distributed NoSQL database service that features high availability and high performance. Tair provides various series of instances based on storage mediums such as DRAM, NVM, and Enterprise SSDs (ESSDs) to meet your requirements for low-latency access, persistence, and reduced overall costs. Tair provides you with higher performance, more data structures, and more flexible storage methods to meet business requirements in different scenarios. For more information, see Overview.
DRAM-based instances: use the multi-threading model and provide read and write performance approximately three times that of Redis Open-Source Edition instances with the same specifications. DRAM-based instances also provide multiple enhanced data modules to eliminate your concerns about storage structures and timeliness and allow you to focus on application development.
Persistent memory-optimized instances: use persistent memory to provide large-capacity in-memory databases that are compatible with open source Redis. A persistent memory-optimized instance persists each operation without the need to rely on traditional disk storage for data persistence. Compared with a Redis Open-Source Edition instance, a persistent memory-optimized instance reduces costs by up to 30% and delivers almost the same throughput and latency. This improves the reliability of business data.
ESSD/SSD-based instances: store data in ESSDs or standard SSDs and are compatible with the core data structures and APIs of open source Redis. ESSD/SSD-based instances can provide large-capacity, low-cost, and persistent database services. ESSD-based instances not only reduce costs and improve data reliability, but also reduce the amount of reserved memory that is required for the forks of open source Redis.
