| /** |
| * This class implements PooledDataSourceFactory for the JDBC Connector extension. |
| * It will be used by default for a data-source with type "POOLED" specified when using |
| * the "gfsh create data-source" command. |
| * <p> |
| * The connection pooling is provided by Hikari, a high-performance JDBC connection pool. |
| * <br> |
| * The following data-source parameters will be will be passed to Hikari as the following: |
| * <br> |
| * connection-url --> jdbcUrl<br> |
| * jdbc-driver-class --> driverClassName<br> |
| * user-name --> username<br> |
| * password --> password<br> |
| * max-pool-size --> maximumPoolSize<br> |
| * idle-timeout-seconds --> idleTimeout<br> |
| * <p> |
| * Additional Hikari configuration parameters may be passed to configure the Hikari pool |
| * by specifying them using the --pool-properties of the "gfsh create data-source" command. |
| * <p> |
| * For more information see the "gfsh create data-source" command. |
| * <br> |
| * Additional Hikari options are described at |
