Foreign table created in Parquet format usually contains the following columns:
  • Location
  • Several other user specified columns in Parquet format specified while creating foreign table

User can create an object of class "tbl_teradata" on a foreign table using "tbl()", similar to creating an object of class "tbl_teradata" on a regular table. With the created tbl_teradata, user can easily access and process the data using various API's offered by tdplyr and other R packages that work with tbl objects.

How to access actual data and path variables

Unlike foreign tables on JSON and CSV format data, tdplyr tbl_teradata on Parquet data provides direct access to the actual data in Parquet files, as described in Accessing Foreign Table Created On Parquet Data.
