Put database settings operation
-
Use
PutDatabaseSettingsOperation
to modify the default database configuration. -
Only database-level settings can be customized using this operation.
See article Configuration overview to learn how to customize the server-level settings. -
Note: for the changes to take effect, the database must be reloaded.
Reloading is accomplished by disabling and enabling the database using ToggleDatabasesStateOperation.
See the following example:
// 1. Modify the database settings:
// ================================
// Define the settings dictionary with the key-value pairs to set, for example:
var settings = new Dictionary<string, string>
{
["Databases.QueryTimeoutInSec"] = "350",
["Indexing.Static.DeploymentMode"] = "Rolling"
};
// Define the put database settings operation,
// specify the database name & pass the settings dictionary
var putDatabaseSettingsOp = new PutDatabaseSettingsOperation(documentStore.Database, settings);
// Execute the operation by passing it to Maintenance.Send
documentStore.Maintenance.Send(putDatabaseSettingsOp);
// 2. RELOAD the database for the change to take effect:
// =====================================================
// Disable database
var disableDatabaseOp = new ToggleDatabasesStateOperation(documentStore.Database, true);
documentStore.Maintenance.Server.Send(disableDatabaseOp);
// Enable database
var enableDatabaseOp = new ToggleDatabasesStateOperation(documentStore.Database, false);
documentStore.Maintenance.Server.Send(enableDatabaseOp);
// 1. Modify the database settings:
// ================================
// Define the settings dictionary with the key-value pairs to set, for example:
var settings = new Dictionary<string, string>
{
["Databases.QueryTimeoutInSec"] = "350",
["Indexing.Static.DeploymentMode"] = "Rolling"
};
// Define the put database settings operation,
// specify the database name & pass the settings dictionary
var putDatabaseSettingsOp = new PutDatabaseSettingsOperation(documentStore.Database, settings);
// Execute the operation by passing it to Maintenance.SendAsync
await documentStore.Maintenance.SendAsync(putDatabaseSettingsOp);
// 2. RELOAD the database for the change to take effect:
// =====================================================
// Disable database
var disableDatabaseOp = new ToggleDatabasesStateOperation(documentStore.Database, true);
await documentStore.Maintenance.Server.SendAsync(disableDatabaseOp);
// Enable database
var enableDatabaseOp = new ToggleDatabasesStateOperation(documentStore.Database, false);
await documentStore.Maintenance.Server.SendAsync(enableDatabaseOp);
Syntax:
PutDatabaseSettingsOperation(string databaseName, Dictionary<string, string> configurationSettings)
Parameter | Type | Description |
---|---|---|
databaseName | string |
Name of database for which to change the settings. |
configurationSettings | Dictionary<string, string> |
The configuration settings to set. |
Get database settings operation
-
Use
GetDatabaseSettingsOperation
to get the configuration settings that were customized for the database. -
Only settings that have been changed will be retrieved.
// Define the get database settings operation, specify the database name
var getDatabaseSettingsOp = new GetDatabaseSettingsOperation(documentStore.Database);
// Execute the operation by passing it to Maintenance.Send
var customizedSettings = documentStore.Maintenance.Send(getDatabaseSettingsOp);
// Get the customized value
var customizedValue = customizedSettings.Settings["Databases.QueryTimeoutInSec"];
// Define the get database settings operation, specify the database name
var getDatabaseSettingsOp = new GetDatabaseSettingsOperation(documentStore.Database);
// Execute the operation by passing it to Maintenance.SendAsync
var customizedSettings = await documentStore.Maintenance.SendAsync(getDatabaseSettingsOp);
// Get the customized value
var customizedValue = customizedSettings.Settings["Databases.QueryTimeoutInSec"];
Syntax:
GetDatabaseSettingsOperation(string databaseName)
Parameter | Type | Description |
---|---|---|
databaseName | string |
The database name for which to get the customized settings. |
// Executing the operation returns the following object:
public class DatabaseSettings
{
// Configuration settings that have been customized
public Dictionary<string, string> Settings { get; set; }
}
