Petar Zecevic created SPARK-26826: ------------------------------------- Summary: Array indexing functions array_allpositions and array_select Key: SPARK-26826 URL: https://issues.apache.org/jira/browse/SPARK-26826 Project: Spark Issue Type: New Feature Components: SQL Affects Versions: 2.4.0 Reporter: Petar Zecevic
This ticket proposes two extra array functions: `array_allpositions` (named after `array_position`) and `array_select`. These functions should make it easier to: * get an array of indices of all occurences of a value in an array (`array_allpositions`) * select all elements of an array based on an array of indices (`array_select`) Although higher-order functions, such as `aggregate` and `transform`, have been recently added, performing tasks above is still not simple, hence this addition. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
