use of com.apple.foundationdb.record.metadata.MetaDataException in project fdb-record-layer by FoundationDB.

 * exists, and the order of any existing fields is preserved. Note that types are identified by name, so renaming
 * top-level message types may result in validation errors when trying to update the record descriptor.
