Release 8.8
What's New
Flow View:
- Updated context panel for output objects. For more information, see View for Outputs.
Changes in System Behavior
Import:
Improvements have been made in how double quotes are handled in CSV files during import to align Trifacta Wrangler with other systems that support CSV import.
Example values in source CSV file:
"""My product""",In stock,"16,000",0.05
Note that the value
16,000must be double-quoted, since the value contains a comma, which is the field delimiter.Previously, this value appeared in the Transformer page in columns as the following:
c1 c2 c3 c4 """My product"""
In stock
"16,000"
0.05
As of this version, the Trifacta application handles the values in a better manner when displaying them in the Transformer page:
c1 c2 c3 c4 "My product"
In stock
16,000
0.05
c1: Escaped values (tripe double-quotes) in the source no longer render in the application as triple double-quotes and are represented as quoted values.
c3: Note that the double quotes in
c3have been stripped. Leading and trailing quotes are trimmed if the quotes are balanced within a cell.NOTE: This change in behavior applies only to newly created imported datasets sourced from a CSV file. Existing imported datasets should not be affected. However, if a newly imported dataset is transformed by a previously existing recipe that compensated for the extra quotes in the Transformer page, the effects on output data could be unpredictable. These recipes and their steps should be reviewed.
This change does apply to any newly imported dataset sourced from CSV and may cause the data to change. For example, if you export an older flow and import into a new workspace or project, this change in parsing behavior applies to the datasets that are newly created in the new environment. Recipes may require review upon import.
When results are generated in CSV, output files should continue to reflect the formatting of the source data before import. See above.
Tip: You can also choose the Include quotes option when creating a CSV output.
When profiling is enabled, values that appear in CSV as
""are now marked as missing.

New Known Issues
| Ticket | Description |
|---|---|
| TD-63517 | Unpivoting a String column preserves null values in Spark but converts them to empty strings in Photon. Running jobs on the different running environments generates different results. Workaround: After the unpivot step, you can add an Edit with formula step. Set the columns to all of the columns in the unpivot and add the following formula, which converts all missing values to null values: IF(ISMISSING($col),NULL(),$col) |
