Want to find Relation between two table(Identify primary key and foreign key by algorithm)

Hi ,

I am ingesting multiple tables in hadoop [CSV files],

during the ingestion process i want to combine /find relation between tables [primary key and foreign key] , join them and create single de-normalize table from all the table

In this case i want to find key by algorithm/code so automatically identify key and merge all tables

Is there any paper available ?

of can any one suggest me some steps to find keys and relations

Thanks ,

Hi, @Paresh Baldaniya. It's irrelevant to Spark SQL itself. If you use MySQL, the same issue exists there. It's completely up to you. You had better search and find some analytics tools for that.
