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") .setShardingKey(shardingKey) .setSuperShardingKey(superShardingKey) .build();
