Add a kernel which replaces null values in an array with a scalar value or with values taken from another array: {code} coalesce([1, 2, null, 3], 5) -> [1, 2, 5, 3] coalesce([1, null, null, 3], [5, 6, null, 8]) -> [1, 6, null, 3] {code} The code in {{take_internal.h}} should be of some use with a bit of refactoring. A filter Expression should be added at the same time. -- This message was sent by Atlassian Jira (v8.3.4#803005)
