Configuration
4 minute read
The parameters listed in the table represent the specific configuration settings that we customize from the default configuration provided by PostgreSQL. These parameters are tailored to suit our platform’s requirements and are carefully selected to optimize performance and reliability.
Note: Parameters marked with an asterisk (*) are dynamically calculated based on available compute resources, allowing for seamless vertical scaling.

Column Explanation
- Parameter: This column lists the configuration parameters.
- Type: Indicates the data type of the configuration parameter (e.g., integer, string).
- Default: Displays the default value for each parameter.
- Modifiable: Indicates whether the parameter can be modified (
true/false). - Restart Required: Specifies whether a server restart is required for changes to take effect (
true/false). - Min: Shows the minimum permissible value for numeric parameters.
- Max: Displays the maximum permissible value for numeric parameters.
- Allowed Values: Lists the values allowed for string parameters.
