17.1.5.3. NDB and InnoDB Feature Usage Summary

When comparing application feature requirements to the capabilities of InnoDB with NDB, some are clearly more compatible with one storage engine than the other.

The following table shows required supported features for applications according to which of these two storage engines each of them is usually better suited:

Preferred application requirements for InnoDB

Preferred application requirements for NDB

  • Foreign keys

  • Full table scans

  • Very large databases, rows, or transactions

  • Transactions other than READ COMMITTED

  • Write scaling

  • 99.999% uptime

  • Online addition of nodes and online schema operations

  • Multiple SQL and NoSQL APIs (see MySQL 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
