High-Performance Scalability
GBase 8a MPP Cluster can expand its computing and storage capacity by adding
server nodes, supporting clusters with hundreds or thousands of nodes, and the
expansion process can be flexibly monitored and managed with features such as
monitoring, pausing, resuming, and canceling. The system supports online
expansion, with linear performance improvement, without interrupting the current
system operation, and supports adding multiple nodes at once. It also supports
flexible expansion at different levels such as instance-level, database-level, and
table-level.

GBase 8a MPP Cluster has high-performance scaling capabilities:
1)
Online dynamic expansion of cluster nodes;
2)
Each node can process 100TB of effective data while providing both
computing and storage capabilities;
3)
Execution
scheduling
nodes
and
data
computing
nodes
can
be
independently scaled as needed.

The last "Execution and Scheduling Node" and "Data Storage and Computation
Node" in the above figure are newly expanded nodes based on the original nodes.
The scheduling nodes or storage and computation nodes can be expanded. Because
GBase 8a MPP Cluster adopts a high-performance single-node MPP architecture, it
can ensure smooth expansion and linear performance growth during cluster
expansion, as shown in the following figure:
