1、在构建实时数仓的时候，通常会把dim层的数据存入hbase，这样做的好处一个是利用hbase的幂等性的功能，维度表基本上都会有数据唯一性，第二个在实时性要求的场景下，可以做数据点查关联，效率上得到一定的保障。

部分sink代码如下：

private transient Connection hbaseConnection;

    private transient Connection hbaseConnection;

    private Admin hbaseAdmin;

    private Table driBaseInfoResTable;


    @Override
    public void open(Configuration parameters) throws Exception {
        super.open(parameters);

        org.apache.hadoop.conf.Configuration configuration = HBaseConfiguration.create();

        configuration.set("hbase.zookeeper.quorum", "192.168.11.1,192.168.11.2,192.168.11.3");

        hbaseConnection = ConnectionFactory.createConnection(configuration);

        hbaseAdmin = hbaseConnection.getAdmin();


        if (!hbaseAdmin.tableExists(TableName.valueOf("test:dim_dri_base_info"))) {
            log.error("hbase table not exists: {}", "test:dim_dri_base_info");
        }

    }


    /**

        Tuple6 tuple6 = new Tuple6<String, Integer, Integer, Integer, Integer, Long>();
