Which version of opengauss supports MOT feature?

It should be introduced in all versions~

The official description is as follows:

openGauss introduces the MOT (Memory-Optimized Table) storage engine, which is a transactional row store optimized for multi-core and large-memory servers.

MOT is the state-of-the-art, production-grade feature of the openGauss database, which provides higher performance for transactional workloads.

Enterprises can use MOT in mission-critical, performance-sensitive online transaction processing (OLTP), which can achieve high performance, high throughput, predictable low latency, and high utilization of multi-core servers.

MOTs are created side-by-side with normal disk-based tables. The efficient design of MOT enables almost complete SQL coverage and supports the full set of database features such as stored procedures and custom functions.
