Abstract
Reducing data skew when performing computational jobs (such as responding to complex queries or queries on big data sets). To gather performance information for a vertex in a distributed stage, the distributed stage is processed and the resulting performance information being generated. The system then identifies a performance outlier of the vertices, which varies from a performance norm of other vertices. A trigger instruction is then generated that is structured to trigger the performance outlier vertex to gather data distribution information of the data that the performance outlier vertex previously processed. The trigger instruction may thus be executed to cause the performance outlier vertex to gather the data distribution information for evaluation for data skew.
