AWS DMS for CDC - Avoid creating new databases/tables

Question

We need to sync a users table on one database instance (MySQL) to a users table on another database instance (Aurora/MySQL 8) in real time by using CDC (change data capture).

We use multitenancy, so we have a ton of schemas (databases) on the source like schema_1, schema_2, schema_3, etc. Each of these schemas has it's own users table.

I want these users tables synchronized in real time to the target, but only if the schema and users table already exists on the target database. I do not want to create new schemas on the target.

One reason why I don't want these schemas and tables to be created is that the users table on the source has a bunch of columns that I do not need on the target. Another reason is that this would complicate database migrations (schema migrations through code).

Is there any way to achieve this?

I have it set to:

Option	Value
Migration Type	Replicate data changes only
Table preperation mode	Do nothing

The table mappings are as follows:

{
  "rules": [
    {
      "rule-type": "transformation",
      "rule-id": "891714557",
      "rule-name": "891714557",
      "rule-target": "schema",
      "object-locator": {
        "schema-name": "dev1_schema_%"
      },
      "rule-action": "add-prefix",
      "value": "aurora-db_",
      "old-value": null
    },
    {
      "rule-type": "selection",
      "rule-id": "891590357",
      "rule-name": "891590357",
      "object-locator": {
        "schema-name": "dev1_schema_%",
        "table-name": "users"
      },
      "rule-action": "include",
      "filters": []
    }
  ]
}
