Cross-Cluster Search Optimization

原文（中文）

A preliminary tag search improves computer functioning by reducing cross-cluster searches. Today's cloud service providers maintain large, distributed datasets stored by multiple clusters having many nodes. Many cross-cluster searches generate no search results, but unsuccessful cross-cluster searches still consume much hardware resources, network bandwidth, and electrical energy. The preliminary tag search eliminates unfruitful cross-cluster searches. The preliminary tag search may identify only the cross-cluster searches that will generate positive search results. The preliminary tag search may identify wasteful cross-cluster searches that would generate no search results. Prior to conducting cross-cluster searches, a distributed database service may first perform the preliminary tag search that identifies successful/unsuccessful cross-cluster searches. The distributed database service may then decline or skip unsuccessful cross-cluster searches.
