>            Reporter: Alexander Lapin
>            Priority: Major

> h3. Motivation
> {code:java}
> client1.sql(CREATE TABLE t1);
> client.beginRO()
> client.sql(SELECT * from t1); // Given request should see t1.
> ...
> {code}
> However it won't be true by default because we may step back for idle safe time propagation period that might be greater than delay duration in metadata sync logic.
> h3. Definition of Done
>  * Both clients and embedded nodes should have an ability to see same-actor schema adjustments though RO requests.
> h3. Implementation Notes
> Seems that it's required to adjust observable timestamp within DDL operations or we may consider setting DD greater than idle safe time propagation period.
