Hi
Has anyone used pmacct on MySQL cluster yet ? And is it possible
knowing the cluster constraints :
* NDB does not support foreign keys or FULLTEXT indexes or indexes on text 
columns
 (indexes on char/varchar are ok).
* Attribute names are automatically truncated to 31 characters.
 Database names and table names can total a maximum of 122 characters
  - the maximum length for an NDB table name is 122 characters,
   less the number of characters in the name of the database of which that 
table is a part.
* The maximum number columns and indexes per table is limited to 128.
* Temporary tables are not supported.
* Every table using the NDBCluster storage engine requires a primary key;
 if no primary key is defined by the user, then a “hidden” primary key will be 
created by NDB.
  This hidden primary key consumes 31-35 bytes per table record.
* The maximum permitted size of any one row is 8KB.
  Note that each BLOB or TEXT column adds 256 + 8 = 264 bytes towards this 
total.

  Thank you for any help

  Peter
