one mode or quantile is required
Yibo Cai created ARROW-11368:
--------------------------------
Summary: [C++][Compute] Return scalar if only one mode or quantile is required
Key: ARROW-11368
URL: https://issues.apache.org/jira/browse/ARROW-11368
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Yibo Cai
Assignee: Yibo Cai
Mode and quantile kernels support returning multiple values and always return vector to hold multiple values. If only one value is required, a vector of size 1 is returned. It's better to return a scalar instead in this case.
