What data types are supported by MySQL Cluster?
MySQL Cluster NDB 6.x, supports all of the usual MySQL data types, including those associated with MySQL’s spatial extensions; however, the NDBCLUSTER storage engine does not support spatial indexes. (Spatial indexes are supported only by MyISAM; see Section 11.13, “Spatial Extensions”, for more information.) In addition, there are some differences with regard to indexes when used with NDBCLUSTER tables.
MySQL Cluster supports all of the usual MySQL data types, with the exception of those associated with MySQL’s spatial extensions. (See 章 16. Spatial Extensions.) In addition, there are some differences with regard to indexes when used with NDB tables. Note: MySQL Cluster Disk Data tables (that is, tables created with TABLESPACE … STORAGE DISK ENGINE=NDBCLUSTER) have only fixed-width rows. This means that (for example) each Disk Data table record containing a VARCHAR(255) column requires space for 255 characters (as required for the character set and collation being used for the table), regardless of the actual number of characters stored therein. See 項14.13. 「MySQL Cluster の既知の制限」, for more information about these issues.
In MySQL 4.1, MySQL Cluster supports all of the usual MySQL data types, except for those associated with MySQL’s spatial extensions. (Spatial data types and spatial indexes are supported only by MyISAM; see Chapter 16, Spatial Extensions, for more information.) In addition, there are some differences with regard to indexes when used with NDB tables.
