ABSTRACT:
The invention relates to a system for maintaining a log of incoming records for a database system. Seek points are inserted into the compressed data log in a manner that allows recovery to start from a specified point without a need for decompressing earlier portions of the log. The initial block of data is used as the compression dictionary. A new compression sequence using the same initial compression dictionary is started at each seek point.
