MySQL 8.4 Release Notes
NDB Cluster has a range of unique attributes that make it ideal
to serve applications requiring high availability, fast
failover, high throughput, and low latency. Due to its
distributed architecture and multi-node implementation, NDB
Cluster also has specific constraints that may keep some
workloads from performing well. A number of major differences in
behavior between the NDB and
InnoDB storage engines with regard
to some common types of database-driven application workloads
are shown in the following table::
