Although you can increase this limit by enabling high throughput mode, you might also consider whether you want to break down your workflow's actions into smaller workflows so that the number of actions that run in each workflow stays under the limit. Refactor actions into multiple, smaller workflows.Īs mentioned earlier, a Consumption logic app workflow is limited to a default number of actions that can run over a 5-minute period. To control throttling, turn off the trigger's Split On behavior and have your workflow process the entire array with a single call, rather than handle a single item per call. This behavior effectively triggers multiple concurrent runs up to the Split On limit. If a trigger returns an array for the remaining workflow actions to process, the trigger's Split On setting divides up the array items and starts a workflow instance for each array item. To raise this limit to the maximum number of actions, turn on high throughput mode on your logic app resource.Ī Standard workflow has no limit on the number of actions that can run during any interval.ĭisable array debatching or "Split On" behavior in triggers. Each trigger instance fires before the previous workflow instance finishes running.Īlthough the default number of trigger instances that can concurrently run is unlimited, you can limit this number by turning on the trigger's concurrency setting, and if necessary, select a limit other than the default value.Ī Consumption workflow has a default limit for the number of actions that can run over a 5-minute rolling interval. Limit the number of workflow instances that can run at the same time.īy default, if your workflow's trigger condition is met more than once at the same time, then multiple instances of that trigger fire and run concurrently or in parallel. To handle throttling at this level, you have the following options: Under Chart Title, from the Metric list, select Http 4xx. For more information, see View metrics for workflow health and performance in Azure Logic Apps. The chart now shows throttled events for both actions and triggers in your logic app workflow. In the second metric bar, from the Metric list, select Trigger Throttled Events. In the first metric bar, from the Metric list, select Action Throttled Events. Under Chart Title, select Add metric, which adds another metric bar to the chart. On the logic app resource menu, under Monitoring, select Metrics. In the Azure portal, open your logic app resource. To find throttling events at this level, follow these steps: If your logic app resource exceeds these limits, your logic app resource gets throttled, not just a specific workflow instance or run. The following sections describe the common levels at which your workflow might experience throttling:Īzure Logic Apps has its own throughput limits. Throttling can create problems such as delayed data processing, reduced performance speed, and errors such as exceeding the specified retry policy.įor example, the following SQL Server action in a Consumption workflow shows a 429 error, which reports a throttling problem: If your logic app workflow experiences throttling, which happens when the number of requests exceed the rate at which the destination can handle over a specific amount of time, you get the "HTTP 429 Too many requests" error. To find out which models can be trained, check out the trainable language models collection.Applies to: Azure Logic Apps (Consumption + Standard) Input and output (including any files) are automatically deleted after an hour, so you must save a copy of any files in the output if you'd like to continue using them. To get the final result of the prediction you should either provide a webhook URL for us to call when the results are ready, or poll the get a prediction endpoint until it has one of the terminated statuses. As models can take several seconds or more to run, the output will not be available immediately. Calling this operation starts a new prediction for the version and inputs you provide.
