Abstract
A method, apparatus, and computer implemented instructions for restricting a fan-out type search of a distributed database. A search request is received indicating that a requesting node originating the search request desires to avoid receiving search results including inaccessible nodes. Responsive to receiving the search results from other nodes, the search results are filtered to remove search results from inaccessible nodes to form filtered search results. The filtered search results are passed to the requesting node.
Claims15
A method in a data processing system for restricting a fan-out type search of a distributed database, the method comprising the data processing system implemented steps of:
- receiving a search request indicating that a requesting node originating the search request desires to avoid receiving search results including inaccessible nodes;
- responsive to receiving the search results from other nodes, filtering the search results to remove search results from inaccessible nodes to form filtered search results;
- passing the filtered search results to the requesting node.
A data processing system for restricting a fan-out type search of a distributed database, the data processing system comprising:
- receiving means for receiving a search request indicating that a requesting node originating the search request desires to avoid receiving search results including inaccessible nodes;
- filtering means, responsive to receiving the search results from other nodes, for filtering the search
- results to remove search results from inaccessible nodes to form filtered search results;
- passing means for passing the filtered search results to the requesting node.
A computer program product in a computer readable medium for restricting a fan-out type search of a distributed database, the computer program product comprising:
- first instructions for receiving a search request indicating that a requesting node originating the search request desires to avoid receiving search results including inaccessible nodes;
- second instructions, responsive to receiving the search results from other nodes, for filtering the search results to remove search results from inaccessible nodes to form filtered search results;
- third instructions for passing the filtered search results to the requesting node.
