Andrew Lamb created ARROW-11164: ----------------------------------- Summary: [Rust][DataFusion] Implement optional second argument to ltrim and rtrim functions Key: ARROW-11164 URL: https://issues.apache.org/jira/browse/ARROW-11164 Project: Apache Arrow Issue Type: Improvement Components: Rust - DataFusion Reporter: Andrew Lamb Attachments: 103891510-f84d8800-50b7-11eb-929e-94f56c2364cd.png
https://github.com/apache/arrow/pull/9108 adds the ltrim and rtrim functions to datafusion, following postgres. However, postgres offers a second optional argument (the character to trim) that is not yet implemented, as described on https://www.postgresql.org/docs/9.1/functions-string.html For example: !103891510-f84d8800-50b7-11eb-929e-94f56c2364cd.png! This ticket tracks the work to add support for the second optional arguments (what character to trim) - it would probably be a good introductory item for new contributors.
