org.apache.hadoop.hive.ql.util.jdbm.RecordManager
An interface to manages records, which are uninterpreted blobs of data.
The set of record operations is simple: fetch, insert, update and delete. Each record is identified using a "rowid" and contains a byte[] data block. Rowids are returned on inserts and you can store them someplace safe to be able to get back to them. Data blocks can be as long as you wish, and may have lengths different from the original when updating. @author Alex Boisvert @author Cees de Groot @version $Id: RecordManager.java,v 1.3 2005/06/25 23:12:31 doomdark Exp $
