The performance of MaxCompute tables depends on whether they comply with table design specifications. To measure the performance of MaxCompute tables, we recommend that you establish a performance benchmark before optimizing tables.
|Test item||Test value|
|Data synchronization time||-|
|Occupied storage space||-|
|Query execution time||-|
|Estimated charge for a query||-|
Record the data synchronization time
Record the occupied storage space
You can run the DESCRIBE command to query the physical storage size of a table or a partition in the table, as shown in the following figure.
Record the query execution time and the estimated charge for a query
If you use DataWorks to query data, you can view the estimated charge on the graphical user interface (GUI) when a node is running or by clicking the icon .After the node is run, you can view the query execution time in the operational log.
