File order matters, the statements of a give file are executed before the statements of the following files. These statements are only executed if the schema is created ie if hibernate.hbm2ddl.auto is set to create or create-drop. The default value is /import.sql

Maximum JDBC batch size. A nonzero value enables batch updates.

Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. If 0, JDBC driver default settings will be used.

TransactionManagerLookup implementor to use for obtaining the TransactionManager

TransactionFactory implementor to use for creating Transactions

JDBC URL

Tells the JDBC driver to attempt to retrieve row Id with the JDBC 3.0 PreparedStatement.getGeneratedKeys() method. In general, performance will be better if this property is set to true and the underlying JDBC driver supports getGeneratedKeys().

Optimize the cache for minimal puts instead of minimal gets

Enable the query cache (disabled by default)

Use bytecode libraries optimized property access
