1.5.6. Interoperability Features Between MaxDB and MySQL

MaxDB and MySQL are independent database management servers. The interoperation of the systems is possible in a way that the systems can exchange their data. To exchange data between MaxDB and MySQL, you can use the import and export tools of the systems or the MaxDB Synchronization Manager. The import and export tools can be used to transfer data in an infrequent, manual fashion. The MaxDB Synchronization Manager offers faster, automatic data transfer capabilities.

The MaxDB Loader can be used to export data and object definitions. The Loader can export data using MaxDB internal, binary formats and text formats (CSV). Data exported from MaxDB in text formats can be imported into MySQL using the mysqlimport client program. To export MySQL data, you can use either mysqldump to create INSERT statements or SELECT ... INTO OUTFILE to create a text file (CSV). Use the MaxDB Loader to import the data files generated by MySQL.

Object definitions can be exchanged between the systems using MaxDB Loader and the MySQL tool mysqldump. As the SQL dialects of both systems differ slightly and MaxDB has features currently not supported by MySQL like SQL constraints, we recommend to hand-tune the definition files. The mysqldump tool offers an option --compatible=maxdb to produce output that is compatible to MaxDB to make porting easier.

The MaxDB Synchronization Manager is available as part of MaxDB 7.6. The Synchronization Manager supports creation of asynchronous replication scenarios between several MaxDB instances. However, interoperability features also are planned, so that the Synchronization Manager supports replication to and from a MySQL server.

In the first release, the Synchronization Manager supports inserting data into MySQL. This means that initially only replication from MaxDB to MySQL is supported. In the course of 2005, exporting of data from a MySQL server to the Synchronization Manager will be added, thus adding support for MySQL to MaxDB replication scenarios.
