Retrieve a key/data pair from the database. In the presence of duplicate key values, Get returns the first data item for key. If the data is a partial DatabaseEntry, PartialLen bytes starting PartialOffset bytes from the beginning of the retrieved data record are returned as if they comprise the entire record. If any or all of the specified bytes do not exist in the record, Get is successful, and any existing bytes are returned.
