Hi Kant, Not sure about what you meant in "query it using SQL"? Do you mean running ad-hoc SQL queries on that joined data? If that's what you meant, then you'll need some SQL server first, then write the joined data to that SQL server. ElasticSearch and Cassandra are ready-to-use options. Writing a custom sink function to write to your own SQL server is also a not-so-difficult solution.
