Hi community, I have submitted two PRs with CALCITE-5825 and CALCITE-5826 to add some useful string functions.
In CALCITE-5825, I have added the URL_ENCODE and URL_DECODE function, which is enabled in Spark library. In CALCITE-5826, I have added the FIND_IN_SET function, which is enabled in Hive and Spark library. If someone has time, please help me to review these two PRs, I would appreciate it very much. 1.CALCITE-5825: Jira: https://issues.apache.org/jira/browse/CALCITE-5825 PR: https://github.com/apache/calcite/pull/3318 2.CALCITE-5826: Jira: https://issues.apache.org/jira/browse/CALCITE-5826 PR: https://github.com/apache/calcite/pull/3317 Best, Runkang He
