Hi, I implemented two array functions that are useful to us and I wonder if you think it would be useful to add them to the distribution. The functions are used for filtering arrays based on indexes:
array_allpositions (named after array_position) - takes a column and a value and returns an array of the column's indexes corresponding to elements equal to the provided value array_select - takes an array column and an array of indexes and returns a subset of the array based on the provided indexes. If you agree with this addition I can create a JIRA ticket and a pull request. -- Petar Zečević --------------------------------------------------------------------- To unsubscribe e-mail: dev-unsubscr...@spark.apache.org
