Abstract
Techniques for performing predicate-based data compression are provided. The techniques include specifying a predicate, wherein the predicate is specified by a user, and using the predicate to filter data compression, wherein using the predicate to filter data compression comprises compressing one or more subsets of data that satisfy the predicate.
Claims20
A method for performing predicate-based data compression, comprising the steps of:
- specifying a predicate, wherein the predicate is specified by a user;
- and
- using the predicate to filter data compression, wherein using the predicate to filter data compression comprises compressing one or more subsets of data that satisfy the predicate.
A computer program product comprising a computer readable medium having computer readable program code for performing predicate-based data compression, said computer program product including:
- computer readable program code for specifying a predicate, wherein the predicate is specified by a user;
- and
- computer readable program code for using the predicate to filter data compression, wherein using the predicate to filter data compression comprises compressing one or more subsets of data that satisfy the predicate.
An apparatus for performing predicate-based data compression, comprising:
- a memory;
- and
- at least one processor coupled to said memory and operative to:
- specify a predicate, wherein the predicate is specified by a user;
- and
- use the predicate to filter data compression, wherein using the predicate to filter data compression comprises compressing one or more subsets of data that satisfy the predicate.
