I have a schedule trigger that executes a pipeline every day once at 6:15 AM. And now my requirement is I have multiple pipelines which I want to run post-completion of my pipeline part of the said schedule trigger. How can I achieve this using the Tumbling window? I don't find a way.
Thanks,
Vivek
You can add a dependency on the scheduling trigger in the Advanced section of the tumbling window trigger settings.

Is there a specific way to have Azure WebJobs trigger a function once on startup without using external messages/triggers? I know there is the RunOnStartup annotation that can be added to the TimerTrigger trigger but that still requires a time interval to run the function on. In my case, I am simply looking to run the function once on the startup.
WebJobs have two types: Continuous and Triggered.
Here is a table describes the differences between continuous and triggered WebJobs.
If you just want your task run once, you could set it triggered manually. Follow this turorial: Create a manually triggered WebJob
Thanks for asking question! Azure WebJob is known for its ‘Event-driven background processing’ method. Further, WebJobs is a feature of Azure App Service that enables you to run a program or script in the same instance as a web app. To elaborate on this there are continuous and triggered types of Web Jobs.
The continuous type; Starts immediately when the WebJob is created. To keep the job from ending, the program or script typically does its work inside an endless loop. If the job does end, you can restart it. But triggered type Starts only when triggered manually or on a schedule.

I have a Multiple pipelines dependent on each other, I want to use Thumbling window trigger, Requesting you to suggested, Is it right approach? Are there any limitations using Thumbling window trigger?

Tumbling window trigger is a more heavy weight alternative for schedule trigger offering a suite of features for complex scenarios(dependency on other tumbling window triggers, rerunning a failed job and set user retry for pipelines).--MSFT documentation
Limitation:
A tumbling window trigger has a one-to-one relationship with a pipeline and can only reference a singular pipeline.
If one of the dependencies triggers fails, you must successfully rerun it in order for the dependent trigger to run.
A tumbling window trigger will wait on dependencies for seven days before timing out. After seven days, the trigger run will fail
I have a got an ADF V2 Pipeline that runs hourly between 7am and 5pm only. So far I have been using an "Event" trigger that runs hourly and it was fine.
But somehow the load started to run for more than one hour.
As a result, the next load would start while the previous one was still running.
I have been trying to use a "Tumbling Window" trigger to create a self dependency on this pipeline so that it waits for the previous one to be completed before running but could not make it work.
If someone has some experience about how to tackle this problem, any insight would be much appreciated.
Max Concurrency property can be used in tumbling window triggers where if it is set to 1 it will not let the other instance of trigger to be initiated until the other one completes.

I have an Azure Batch service set up with a job schedule that runs every minute.
The job manager task creates 3-10 tasks within the same job.
Sometimes, one of these tasks within the job may take extremely long to complete but usually are very fast.
In the event that one of the tasks takes long to apply, the next iteration of the job manager task does not begin in that case. It basically waits till all the tasks from the previous iteration have completed.
Is there a way to ensure that the job schedule keeps creating a version of the job every minute even if all the tasks from its previous iteration have not been completed?
I know one option is to make the job manager task create additional jobs instead of tasks. But preferably, I was hoping there is some configuration at the job schedule level that I can turn on that will allow the schedule to create tasks without the dependency of completion on the previous job.
This seems like more towards design question, AFAIK, No, the duplicate active job names should not be doable from az batch perspective. (I will get corrected if at all this is doable somehow)
Although in order to further think this you can read through various design recommendations via Azure batch technical overview page or posts like:
How to use Azure Batch in an event based design and terminate/cleanup finished jobs or
Add Tasks to a running Azure batch job and manually control termination
I think simplicity will be better like handling each iteration with unique job name or some thing of other sort but you will know your scenario better. Hope this helps.
Currently, a Job Schedule can have at most one active Job under it at any given time (link) so the behavour you're seeing is expected.
We don't have any simple feature you can just "turn on" to achieve concurrent jobs from a single job schedule - but I do have a suggestion:
Instead of using the JobSchedule to run all the processing directly, use it to create "worker" jobs that do the processing.
E.g.
At 10:03 am, your job schedule triggers to create job processing-20191031-1003.
At 10:04 am, your job schedule triggers to create job processing-20191031-1004.
At 10:05 am, your job schedule triggers to create job processing-20191031-1005.
and so on
Because the only thing your job schedule does is create another job, it will finish very quickly, ensuring the next job is created on time.
Since your existing jobs already create a variable number of tasks (you said 3-10 tasks, above), I'm hoping this won't be a very complex change for your code.
Note that you will need to ensure your concurrent worker jobs don't step on each others toes by trying to do the same work multiple times.
Currently from the Azure portal (old portal) when setting up a scheduled job start time, you can only specify times as half hour intervals like 12:00 or 3:30 but you can't tell it to start from say 12:55. Is there another way to set up a scheduled job that allows for any start time?
You can either use the new portal, which enables you more advanced options along side with the ability to set the scheduling to a minute granularity. Or use the REST api to do a request with a specific time/interval.
Hope this helps!
