Latest Patents

Yash Shah holds a patent titled "Handling data skew for parallel execution with server mapping plans." This patent introduces skew handling techniques that facilitate even load balancing and scaling during parallel execution. The compile-time solution involves issuing a dynamic sampling query to detect partition skew. It determines the number of skewed partitions and employs a hybrid distribution scheme, where skewed partitions utilize a random distribution while non-skewed partitions maintain the original server mapping. In the runtime solution, producer server processes create partition mapping vectors containing essential mapping information. Each producer server process sends its partition mapping vector to the query coordinator (QC), which merges the vectors and determines a skew result based on the merged mapping. The producer server process can then adjust the distribution of skewed partitions according to the skew result.
