 **MOT Engine (beta release)**
 
-The Memory-Optimized Tables (MOT) storage engine is a transactional rowstore optimized for many-core and large memory and delivering extreme OLTP performance and high resources utilization. With data and indexes stored totally in-memory, a NUMA-aware design, algorithms that eliminate lock and latch contention and query native compilation (JIT), MOT provides low latency data access and more efficient transaction execution. See [MOT Engine documentation](https://opengauss.org/en/docs/1.1.0/docs/Developerguide/mot.html).
