bag_merge

The bag_merge function merges two or more property bags, discarding duplicate keys.

Syntax

​

     bag_merge( Bag1, Bag2[, ...] )

Parameters

​

Returns

​

Returns a single property bag containing the merged results of all input bags.

If the same key is present in multiple input bags, only the value associated with the key from the leftmost argument is kept.

The order of the key-value pairs returned is undetermined.

Example

​

print foo = dynamic({'A1':12, 'B1':2, 'C1':3}), bar = dynamic({'A2':81, 'B2':82, 'A1':1})
 | project result = bag_merge(foo, bar)

Input (before bag_merge):

{
  "foo": {
    "A1": 12,
    "B1": 2,
    "C1": 3
  },
  "bar": {
    "A2": 81,
    "B2": 82,
    "A1": 1
  }
}

Output (after bag_merge):

{
  "result": {
    "A2": 81,
    "B2": 82,
    "A1": 12,
    "B1": 2,
    "C1": 3
  }
}
