Query Planning

This section describes the method configuration, cost constants, planning algorithm, and some configuration parameters for the optimizer.

Two parameters are involved in the optimizer:
- INT_MAX indicates the maximum value of the INT data type. The value is 2147483647.
- DBL_MAX indicates the maximum value of the FLOAT data type.
In addition to customer services, global query planning parameters also affect database O&M and monitoring services, such as WDR generation, scale-out, redistribution, and data import and export.
