Use PowerExchange for MapR-DB to read data from column families in a MapR-DB binary table or write data to column families in a MapR-DB binary table. You can read data from or write data to a column family or a single binary column.

You can connect to a MapR-DB data store and view all the MapR-DB binary tables. When you select a MapR-DB table, you can view all the column families. If you know the schema of the data source, you can specify the columns in the column families when you create the data object. If you do not know the schema of the data source, you can search the rows in a MapR-DB table to identify the columns and their occurrence probability.

You can validate and run MapR-DB mappings in the native environment or on the Blaze and Spark engines in the Hadoop environment.
