1.2.3 Scale-out for load distribution (Multi-node function)

One database can be shared by multiple HADB servers, which enables multiple HADB servers to coordinate the processing. This makes it possible to use the scale-out technique to realize the load distribution. Server machines can be added as necessary afterwards, which allows for scaling out based on the expansion of business operations.

Note

The function that executes processing by linking multiple HADB servers is called the multi-node function.
