Ian Cook created ARROW-13561: -------------------------------- Summary: [C++] Implement week kernel that accepts DayOfWeekOptions Key: ARROW-13561 URL: https://issues.apache.org/jira/browse/ARROW-13561 Project: Apache Arrow Issue Type: Improvement Components: C++ Reporter: Ian Cook
Arrow has an {{iso_week}} compute kernel that follows the [ISO 8601 week date definition|https://en.wikipedia.org/wiki/ISO_week_date#First_week]. Add another kernel (maybe named {{week}}) that lets you specify options for how exactly to count weeks, like MySQL's week function: [https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_week|https://www.google.com/url?q=https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html%23function_week&sa=D&source=editors&ust=1628103672101000&usg=AFQjCNHap0KtiiZ83G_PVRPz5T7z6y-lIQ]. I think we can reuse the existing {{DayOfWeekOptions}} to specify the options. -- This message was sent by Atlassian Jira (v8.3.4#803005)
