Transformation Override for HDFS Targets

Transformation Override for HDFS Targets

When you configure a transformation override for an HDFS target, you can edit the mass transformations that are applied to specific source tables when they are ingested to the HDFS target.
The following image shows the transformation override that you can configure for an HDFS target:
This screenshots shows the Transformation Override page of the mass ingestion specification. Each row defines one table in the specification and each column defines a different parameter that you can configure. The cells define the specific parameter that you configure for a specific table. You edit the parameters by clicking an empty box or by clicking the pencil icon. In the top-right corner, you have the option Save to save the specification, or the button X to discard the specification.
You can edit the following properties for each target table:
  • Filter By. Filter the columns in the source tables.
  • Drop Columns. Drop columns from the source tables.
  • Replace Columns. Replace values in the source table columns.
  • Trim. Trim spaces from the beginning and end of values in source table columns.
  • Convert to Uppercase. Convert values in source table columns to uppercase.
  • Convert to Lowercase. Convert values in source table columns to lowercase.
