Feature: Vector to Columns JIRA: MADLIB-1240 The vec2cols function enables users to split up a single column into multiple columns, given that the input column contains array entries. For example, if the input column contained ARRAY[1, 2, 3] in one of its rows, the output table will contain 3 different columns, one for each element of the array.
