Abstract
Tables in a database can include an internal RowID column. For each new row or new version of a row in the table, a new RowID can be assigned and stored in the RowID column. RowID values can be stored using either or both of range compression and block compression, or other compression approaches. In response to receipt of a query of the database table, at least one of a forward look up and a reverse lookup of a DocID value associated with a specific RowID value can be performed.
