ENHANCEMENTS FOR OPTIMIZING QUERY EXECUTIONS

摘要

In an approach for optimizing query executions a processor receives a request to transfer data from a first table to a second table. A processor detects a relationship between the first table and the second table, wherein the relationship is based on a similarity between the first table and the second table. A processor identifies at least a first access path for transferring the data from the first table to the second table. A processor calculates a first cost of transferring the data from the first table to the second table using the first access path based on the similarity between the first table and the second table, wherein the first cost indicates estimated processor usage to transfer the data.
