There are several ways to do this. The design was meant to be extended by a trait that would do the actual read/write. Check out TDIndexedDatasetReader. You can create a similar trait called MySQLIndexedDatasetReader. There are other examples in that file for reading and writing. Also check the driver for how they are used.
If you don’t like any of those you can use them to write your own code. The IndexedDataset includes an RDD based DRM with int keys to rows and columns, it also includes BiMaps called BiDictionary to translate back and forth between the ints and the original string row and column ids.

After running spark-rowsimilarity I want to read data returned by function directly write it back to mysql db. But I don;t know how to read the data from indexeddataset returned by val data = SimilarityAnalysis.rowSimilarityIDS(myIDs) In debugger it shows datatype as Indexeddataset which contains (matrix,rowIDs,columnIds).
