Time Expansion Ratio of how long the query took to execute versus how long it could have ideally run. The larger the number, the more the execution time of the query was expanded. For example, a value of 10x to indicates an expansion of 10 times the ideal execution time.
Total AMP CPU Total amount of CPU consumed by AMPs in processing queries
Total I/O Total number of I/O requests
