What column types are supported by MySQL Cluster?
MySQL Cluster supports all of the usual MySQL column types, with the exception of those associated with MySQL’s Chapitre 18, Données spatiales avec MySQL. In addition, there are some differences with regard to indexes when used with NDB tables. Note: In MySQL 4.1 and 5.0, Cluster tables (that is, tables created with ENGINE=NDBCLUSTER) have only fixed-width rows. This means that (for example) each record containing a VARCHAR(255) column will will require 256 bytes of storage for that column, regardless of the size of the data stored therein. This issue is expected to be fixed in MySQL 5.1.See Section 16.8, « Cluster Limitations in MySQL 4.1 » for more information about these issues.
