Writing to iModels using IModelDb
An IModelDb also serves as a staging area where a backend can change the content of an iModel and then submit the changes to iModelHub.
A backend can make the following kinds of changes:
Use IModelDb.pushChanges to push local changes to iModelHub as a changeset, so that others can see them. After a changeset is pushed to iModelHub, it becomes part of the iModel's permanent timeline. This method automatically pulls and merges new ChangeSets from iModelHub.
Only a single application can push to iModelHub at a time. IModelDb.pushChanges automatically retries push on appropriate failures. However, it is possible that all retry attempts fail, if there are a lot of other applications pushing at the same time. In that case, push should be attempted again later.
An app that modifies models, elements, or codes must use ConcurrencyControl to coordinate with other users.
