Nate Clark created ARROW-13028: ---------------------------------- Summary: [C++] CSV add convert option to attempt 32bit number inferences Key: ARROW-13028 URL: https://issues.apache.org/jira/browse/ARROW-13028 Project: Apache Arrow Issue Type: Improvement Components: C++ Reporter: Nate Clark Assignee: Nate Clark
When types are being inferred by CSV the numbers are always 64 bit. For large data sets it could be better to use 32 bit types to save over all memory. To do this it would be useful to add an option to ConvertOptions to try 32 bit numbers before 64 bit. By default this option would be disabled. -- This message was sent by Atlassian Jira (v8.3.4#803005)
