Subject [GitHub] madlib pull request #291: Feature: Vector to Columns
Date Wed, 11 Jul 2018 19:09:04 GMT
GitHub user ArvindSridhar opened a pull request:

    https://github.com/apache/madlib/pull/291

    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.
