Connection Pools and Data Sources previous: datasource.html nexttitle: Applications DataSource next: ds-ds.html --- PostgreSQL™ includes one implementation of `ConnectionPoolDataSource` named `org.postgresql.ds.PGConnectionPoolDataSource`. JDBC requires that a `ConnectionPoolDataSource` be configured via JavaBean properties, shown in [Table 11.1, “`ConnectionPoolDataSource` Configuration Properties”](ds-cpds.html#ds-cpds-props), so there are get and set methods for each of these properties. **Table 11.1. `ConnectionPoolDataSource` Configuration Properties**
