-- register the HBase table 'mytable' in Flink SQL

 rowkey INT,
 family1 ROW<q1 INT>,

) WITH (

);

-- use ROW(...) construction function construct column families and write data into the HBase table.
-- assuming the schema of "T" is [rowkey, f1q1, f2q2, f2q3, f3q4, f3q5, f3q6]
INSERT INTO hTable
SELECT rowkey, ROW(f1q1), ROW(f2q2, f2q3), ROW(f3q4, f3q5, f3q6) FROM T;

-- scan data from the HBase table
SELECT rowkey, family1, family3.q4, family3.q6 FROM hTable;

-- temporal join the HBase table as a dimension table
SELECT * FROM myTopic
LEFT JOIN hTable FOR SYSTEM_TIME AS OF myTopic.proctime
ON myTopic.key = hTable.rowkey;
