At ArcGIS Enterprise 10.9.1 or higher it is recommended that you add or edit big data file shares through your portal contents page instead of ArcGIS Server Manager. Learn more about adding big data file shares in the portal.
Hints allow you to provide help to manifest generation with delimited file parameters such as field names, encoding, field delimiter, and quote characters. It is recommended that you upload a hints file before editing individual datasets if the file and datasets include the following characteristics:
- You have a delimited file without headers, and want to apply field names to your data.
- The quote and delimiter characters were not recognized when the manifest was first generated.
- The encoding of your dataset was not recognized.
If you upload a hints file, you need to regenerate the manifest. Only datasets with hints provided or new datasets will be updated, and changes made to any other datasets not in the hints file will remain the same.
The following is an example of a hints file, outlining hints for datasets named hurricanes and earthquakes:
# earthquake dataset (# means comment)
# hurricane dataset
The following table outlines the hints parameters:
The names of the fields to be used for the specified dataset. This is useful for delimited files without headers.
The type of delimiter applied to separate fields.
The character used for quotes.
The type of encoding applied.
Character that marks the end of a record.
Flag indicating whether the delimited file has a header row.
