hibernate default connection pooling

Question

Does Hibernate use connection pool by default? If so what is the default value for *connection.pool_size*? Doesn\'t it conflicts with *hibernate.connection.release_mode*? Is

Answer 1

I found no documentation about Hibernate default values for connection pool, so I looked in the source code and found (class DriverManagerConnectionProviderImpl in hibernate-core-4.3.8.Final):

hibernate.connection.initial_pool_size = 1;
hibernate.connection.min_pool_size = 1;
hibernate.connection.pool_size = 20;
hibernate.connection.pool_validation_interval = 30;
hibernate.connection.autocommit = false;
