Entity columns can be persisted in the storage as any Java type including non-`Comparable` ones. When querying for column value, some implementations (for example, [jdbc one](https://github.com/SpineEventEngine/jdbc-storage/blob/master/rdbms/src/main/java/io/spine/server/storage/jdbc/query/QueryPredicates.java)) may require that column...
