Benjamin Kietzman created ARROW-5423: ----------------------------------------
Summary: [C++] implement partial schema class to extend JSON conversion Key: ARROW-5423 URL: https://issues.apache.org/jira/browse/ARROW-5423 Project: Apache Arrow Issue Type: New Feature Components: C++, Python Reporter: Benjamin Kietzman Assignee: Benjamin Kietzman Currently the JSON parser supports only basic conversion rules such as parsing a number to {{int64}}. In general users will want more capable conversions like parsing a base64 string into binary or parsing a column of objects to {{map<string, string>}} instead of {{struct<string...>}}. This will require extension of {{arrow::json::ParseOptions::explicit_schema}} to something analagous to a schema but which supports mapping to more than a simple output type. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
