DynamoDB - Update Map Object by appending Another Map Object to it

Question

I want to update a Map Object in DynamoDB by adding another map object to it.

Here they add a single key value pair to a map. I want to add multiple key value pairs to a map in one request. There should be something like map_append similar to list_append. How can I do this? I went through the docs but could not find anything similar.

Thanks in advance!

Just use multiple SET update expressions separated by commas, following the example of the question you cited. SET map.#number1 = :string1, map.#number2 = :string2, map.#number3 = :string3
