Working with Amazon DMS endpoints

An endpoint provides connection, data store type, and location information about your data store. Amazon Database Migration Service uses this information to connect to a data store and migrate data from a source endpoint to a target endpoint. You can specify additional connection attributes for an endpoint by using endpoint settings. These settings can control logging, file size, and other parameters; for more information about endpoint settings, see the documentation section for your data store.
