updateBulk Only Updating Last Record, Missing Updates for Other Records with the Same Key

[tanchekwei]

Below example updating as expected, Each item in the array contains both the content and done keys in its changes property.

await Messages.table.bulkUpdate([
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello!",
            "done": false
        }
    },
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello! How",
            "done": false
        }
    },
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello! How can I",
            "done": false
        }
    },
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello! How can I assist",
            "done": false
        }
    }
])

However, the code below only updates the last item in the array, which only updates { done: true }, causing the content changes in the other array items to be missing.

[
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello! How can I assist you",
            "done": false
        }
    },
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello! How can I assist you today",
            "done": false
        }
    },
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "content": "Hello! How can I assist you today?",
            "done": false
        }
    },
    {
        "key": "ffce6291-2fdf-4103-9960-1b208da10222",
        "changes": {
            "done": true
        }
    }
]

Is the behavior of updateBulk intentional when passing in array items with the same key?"

Interesting. I don't think that use case was anticipated when implementing it, but it would probably make sense to support it and apply all changes
