The HBase Adapter supports standard SQL joins like the following examples.

Inner Join

An inner join selects only rows from both tables that match the join condition:

SELECT Opportunity.Name, Account.Name FROM Account INNER JOIN Opportunity ON Account.Id = Opportunity.AccountId

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

 SELECT Opportunity.Name, Account.Name FROM Account LEFT JOIN Opportunity ON Account.Id = Opportunity.AccountId
