Abstract
A journaled database system may comprise data nodes that maintain a collection of data and provide read access to the data to a client in accordance with a read schema and write access to the client in accordance with a write schema. A change to the schemas may be proposed. A materialization schema may be identified based on correlated determinations that both of the read schema and the write schema are satisfiable based on the materialization schema. The proposed changes may be accepted when the read schema and write schema are simultaneously satisfiable.
