public interface ConnectionBuilder
DataSource
object, used to establish a connection to the database that the data source
object represents. The connection properties that were specified for the data source
are used as the default values by the ConnectionBuilder
. The following example illustrates the use of ConnectionBuilder
to create a Connection
:
DataSource ds = new MyDataSource();
ShardingKey superShardingKey = ds.createShardingKeyBuilder()
.subkey("EASTERN_REGION", JDBCType.VARCHAR)
.build();
ShardingKey shardingKey = ds.createShardingKeyBuilder()
.subkey("PITTSBURGH_BRANCH", JDBCType.VARCHAR)
.build();
Connection con = ds.createConnectionBuilder()
.user("rafa")
.password("tennis")
.shardingKey(shardingKey)
.superShardingKey(superShardingKey)
.build();
