The queries in KADB are usually I/O-bound. When customers desire high performance for near-realtime processing, the best way is to cache all the needed data in memory to reduce IO. However, this approach is currently limited by memory capacity, and can be cost-prohibitive for large datasets.
With Intel® Optane™ DC persistent memory (App Direct Mode), Kingbase can take advantage of the larger memory capacities per socket to store data closer to the CPU and eliminate the I/O bottleneck, while achieving better price-performance (see chart).1 2 3
Improved price-performance: Kingbase customers will benefit from similar performance (being able to process almost the same number of transactions per second), at lower cost2, and while meeting SLA targets for the response time.
