See additional notes below on storage engine.

Creating

Here is a quick example:

java.util.Map params = new java.util.HashMap();
params.put(MySQLDataStoreFactory.DBTYPE.key, "mysql");
params.put(MySQLDataStoreFactory.HOST.key, "localhost");
params.put(MySQLDataStoreFactory.PORT.key, 3309);
params.put(MySQLDataStoreFactory.DATABASE.key, "database");
params.put(MySQLDataStoreFactory.USER.key, "geotools");
params.put(MySQLDataStoreFactory.PASSWD.key, "geotools");

DataStore dataStore=DataStoreFinder.getDataStore(params);

Storage Engine

The MySQL Datastore is capable of creating new tables via DataStore.createSchema(). The storage engine connection parameter controls what storage engine is used for the new table. The default is MyISAM which is the only engine that supports spatial indexing. However depending on the use of the able other engines may be appropriate. For instance InnoDB is fully transaction safe so is more suitable to tables that will be undergoing many concurrent edits.

Example:

params.put(MySQLDataStoreFactory.STORAGE_ENGINE, "MyISAM");
