Profile metrics

In the Path Information view, the area to the right of each query path contains profile metrics for that path.

• Disk—Bytes of data accessed from disk by each query path. If none of the query paths accessed the disk data, all the values are 0.

• Memory—Bytes of data accessed from memory by each query path.

• Sent—Bytes of data sent across the cluster by each query path.

• Received—Bytes of data received across the cluster by each query path.

• Time—Number of milliseconds (ms) that the query path took to process on a given node, shown on progress bars. The sum of this data does not match the total time required to execute the query. This mismatch occurs because many tasks are executed in parallel on different nodes.

  Hover over the progress bars to get more information, such as total bytes and percentages.

  Note

  The time data in the profile metrics might not match the times in the Query phase duration chart. These times can differ because the query phase duration graph uses the longest execution time for a given phase from all the nodes. Network latency can add more data, which is not taken into account in these calculations.
