You can programmatically update the start time of your ADF schedule triggers using the Azure Data Factory REST API.
- Using the ADF REST API, create a web service that reads the start time from the SQL Server table and updates the schedule trigger.
- Using a timer trigger in Azure Functions or Logic Apps, call the web service on a regular basis (for example, every minute). This ensures that the schedule trigger is dynamically updated based on the SQL Server table values.
- Set up your ADF pipeline to use the new schedule trigger. This can be accomplished by either adding a new trigger or updating an existing trigger in your pipeline definition.
You can modify the following code block according to your requirements
// Construct the REST API URL for the schedule trigger
string triggerUrl = $"https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataFactory/factories/{factoryName}/triggers/{triggerName}?api-version=2018-06-01";
DateTime newStartTime = ReadNewStartTimeFromSqlTable();
string payload = $"{{ 'properties': {{ 'startTime': '{newStartTime.ToString("s")}' }} }}";
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
HttpContent content = new StringContent(payload, Encoding.UTF8, "application/json");
HttpResponseMessage response = await client.PatchAsync(triggerUrl, content);
if (response.IsSuccessStatusCode)
{
Console.WriteLine("trigger updated");
}
else
{
string errorResponse = await response.Content.ReadAsStringAsync();
Console.WriteLine(errorResponse);
}
