The $pushAll operator is similar to the $push but adds the ability to append several values to an array at once.
db.collection.update( { field: value }, { $pushAll: { field1: [ value1, value2, value3 ] } } );
Here, $pushAll appends the values in [ value1, value2, value3 ] to the array in field1 in the document matched by the statement { field: value } in collection.
If you specify a single value, $pushAll will behave as $push.
