I’m creating a data model where performant reads, and consistent data across references take precedence over writes.

What are best practices for CRUD update operations on a document field, and all documents that reference that document and also stores some of the associated information?

Example:

Collection A

{
    _id: 123,
    title: "Document title",
    body: "Lorem ipsum dolor sit amet..."
}

Collection B

{
    _id: 456,
    name: "Another document 01",
    collectionA: {
        _id: 123,
        title: "Document title"
        }
}

Collection C

{
    _id: 789,
    name: "Another document 02",
    collectionA: {
        _id: 123,
        title: "Document title"
        }
}

Collection A UPDATED

{
    _id: 123,
    title: "New Document title added!",
    body: "Lorem ipsum dolor sit amet..."
}
