• # of interactions with Anypoint Exchange assets
• # of APIs managed by Anypoint Platform
• # of System APIs managed by Anypoint Platform
• # of API clients registered for access to APIs
• # of API implementations deployed to Anypoint Platform
• # of API invocations
• # or fraction of lines of code covered by automated tests in CI/CD pipeline
• Ratio of info/warning/critical alerts to number of API invocations

What is output of Dataweave flatten function?


A. Object


B. Map


C. Array


D. LInkedHashMap





C.
  Array

Explanation:
Correct answer is Array.
Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [ 1, 2, 3, 4, 5, [6], null ]).
This example defines three arrays of numbers, creates another array containing those three arrays, and then uses the flatten function to convert the array of arrays into a single array with all values.
Source
%dw 2.0
output application/json
var array1 = [1,2,3]
var array2 = [4,5,6]
var array3 = [7,8,9]
var arrayOfArrays = [array1, array2, array3]
---
flatten(arrayOfArrays)
Output
[ 1,2,3,4,5,6,7,8,9 ]
