RonDB supports read-what-you-write consistency which is actually more than any eventual consistency database provides. Thus when you have written something into RonDB you can trust that it is seen by you and others. RonDB provides row locking, this means that the application can provide a stricter guarantee if desirable. Concurrency control and consistency in a database is too complex to handle here, for an in-depth coverage of RonDB consistency, see https://docs.rondb.com/rondb_concepts/
