Todd Farmer reassigned ARROW-13028: ----------------------------------- Assignee: (was: Nate Clark) > [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 > Priority: Major > Labels: pull-request-available > Time Spent: 40m > Remaining Estimate: 0h > > 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 (v8.20.10#820010)
