Hello, I am working on converting some internal data sources to Arrow data. One particularly sets of data we have contains many string columns that can be dictionary-encoded (basically string enums)
The current internal C++ API I am using gives me an iterator of "row" objects, for each string column, the row object exposes a method "getStringField(index)" that return me a "string_view" and I want to construct a dictionary-encoded Arrow string column from it. My question is: (1) Is there a way to do this using the Arrow C++ API? (2) Does the internal C++ API need to return something other than a "string_view" to support this? Internally the string column is already dictionary-encoded (although not in Arrow format) and it might already know the dictionary and the encoded (int) value for each string field, but it doesn't expose it now. Thanks, Li
