Why Oracle MySQL with HA only provides single primary node with 3-nodes cluster?

Hi there!

I am finding any mysql cloud service which provides HA based on InnoDB Cluster with multi-primary and clusters with more than 5 nodes.

According to MySQL official documentation, InnoDB Cluster have multi-primary mode and more cluster nodes. But orcale mysql cloud service provides only single primary node with 3-nodes cluster.

My business needs database which is capable of handling large volumes of traffic with high TPS.

And I need db with extensible strucure to scale out cluster nodes when my business needs to cope with more traffic.
