When comparing application feature requirements to the capabilities of InnoDB withNDB, some are clearly more compatible with one storage engine than the other.
The following table lists supported application features according to the storage engine to which each feature is typically better suited.

| Preferred application requirements forInnoDB | Preferred application requirements for NDB |
|---|---|
| Foreign keys Note NDB Cluster 7.5 supports foreign keys Full table scans Very large databases, rows, or transactions Transactions other thanREAD COMMITTED | Write scaling 99.999% uptime Online addition of nodes and online schema operations Multiple SQL and NoSQL APIs (seeNDB Cluster APIs: Overview and Concepts) Real-time performance Limited use of BLOB columns Foreign keys are supported, although their use may have an impact on performance at high throughput |
