When percentage is an array, each value of the percentage array must be between 0.0 and 1.0. The regex string should be a Java regular expression. The function returns null for null input. timeExp - A date/timestamp or string. The function returns NULL if the index exceeds the length of the array and but we can not change it), therefore we need first all fields of partition, for building a list with the path which one we will delete.
