Use Cases of Tumbling Window: - It creates windows for the set recurrence time. Each window have a window starttime and endtime. These variables can be accessed in pipeline expression language using system variables from tumbling window trigger. 1. In Copy Data from RDBMS, we can use these start and end variables to fetch the incremental data. 2. Tumbling window can be set for older days for backfilling. We can set older start and older end date and load older data without disturbing regular loads through scheduled trigger. Trigger starts at windowEndTime, for data b/w windowStartTime and windowEndTime. Delay option: Instead of starting at windowEndTime, it will start at windowEndTime + delay. Concurreny: Number of windows which can run in parallel. (Helpful in historical load)
Thanks for sharing your knowledge. Also instead of explaining the features of tumbail triggers, if you can create quickly create a pipeline and schedule it using the tumbail triggers and show us advantages over schedule triggers , it will help us to understand better...
I can see history and future dates in the Schedule Trigger also (main advantage you mentioned). How does it make it different from Tumbling window then? Dependency and Concurrent runs are the only additional features. Thanks!
The main differences are you can use system variables to get the schedule times from Tumbling window. For example, you can have you SQL like this, select * from xxx where time between tumbling start and tumbling end(pseudo code). In schedule trigger, it doesn't interact with your pipeline.
@WafaStudies Hello Brother, Explanation in the video is superb. I have a query in one of the point which was said. You mentioned "In schedule trigger, we will not be able to schedule from back dates and its only available in tumbling trigger". But I am able to create a schedule trigger with old dates. Can you please suggest
Hello, Brother some great work was done here in these tutorials... Can you please put the presentation as well so that we can use them for reference...
So trigger can be activated for historic date, they it will be executed at once in the present date or will it execute as per day by day in the present date taking historic date .
Using tumbling window in one window time frame you mean to say we will get the data in that window time frame only na ? i.e from 5:14 AM to 6:14 AM whatever data is there new we will get that only right? It will not take the whole data from past.
I have a requirement to trigger a pipeline on First Thursday of the month Followed by Wednesday? Example: If 1st of the month is Thursday then pipeline should be triggered on 8th i.e. the first Thursday followed by a Wednesday. Otherwise trigger on first Thursday.
Hi. Great info. Quick question. Does Tumbling triggers only give access to startdate and enddate output Parameters or i can access any other parameters through them ?
Hi , I am following your videos from last 1 month...Great effort... Just want to know one thing why one will backfill the dates in the tumbling window triggers
Hi , I have a requirement to process files on daily basis I am using tumbling window. Can I pass tumbling window trigger time as a pipeline parameter to dataflow parameter in last modified date under dataflow source settings. If yes,please let me know how.

Yet another nice video, thanks. However, I have two things I am still not clear on, 1. Historic data processing. Lets assume if I am setting trigger start date as past date then would that trigger even fire tasks? As it will check what's date its supposed to start and that past date will never come. So, I think trigger will never fire for historic date. 2.You mentioned about Tumbling Window Triggers maintain 'state'. However, didnt elaborate what does 'maintaining state' means. Please explain.
Hi.. once data is pulled on real time basis from source db to target db.. I need to apply complex transformation aggregation on huge set of data and it's multi hierarchy. What approach do you recommend to do this transformation on real time basis for huge set of data for reporting purpose?
Thanks For Sharing knowledge but i am confused how can it possible historical date will run in current date for example hisorical date 6 mar 2021 and current date is 2 aug 2022. Please describe briefly.
In tumbling trigger you given past time ..actual your laptop time 10:45 AM. but start time 5:45 AM .. is there any use giving past time to start time..?
if max concurrency is 50, then once it starts execution, lets say 1 window trigger is finished first & rest 49 triggers are still work in progress. In that case, will it wait until all rest 49 triggers are finished? or it will automatically start 51st trigger?

I always used to confuse between Scheduled and tumbling trigger. You have explained it so well. Thanks!!!
Welcome 😄
very detailed explanation on adf i came across so far! thank you for the videos! keep posting :)
Thank you 🙂
Very good video..please continue to keep on this type of post..
Thank you a lot ...I understood clearly ... Explanation is very clear😊
Welcome 🤗
Very nice explanation brother. Keep it up. It helped me a lot really. !!
Thank you ☺️
Great job man,keep it up,Thanks
Thank you 😊
fantastic explanation sir...
Tumbling window concepts cleared !
why do we need to run the trigger in back date can you please explain and how we will get the data for that particular back date?
Thanks for sharing your knowledge. Also instead of explaining the features of tumbail triggers, if you can create quickly create a pipeline and schedule it using the tumbail triggers and show us advantages over schedule triggers , it will help us to understand better...
Agree. But at that time I didn't had an free subscription to run that. But surely in my real-time scenarios playlist I will do one video on that.

It suited for Bank Transaction, Share Market Trades (Profit/Loss) particular duration in past

Can we create a dependency in between tumbling window and other triggers?
Is there anyway to adjust the tumbling window trigger to adjust according to US daylight savings?
If you select past time, all those windows match the criteria then how they will execute all at once?

Example:
If 1st of the month is Thursday then pipeline should be triggered on 8th i.e. the first Thursday followed by a Wednesday. Otherwise trigger on first Thursday.

If current window is running and new window has arrived, what will happen..? Will it stop current execution and will re-trigger for it new scheduled ?
same doubt .i want trigger to wait till the previous trigger is completed .

Explained so well, @wafastudies can u share the ppt please.
nice explanation, what kind of windows we create through the triggers

Same question.. How does it trigger on historic date or is it the date it run on SQL query to get historic data?? Plz explain

Thanks For Sharing knowledge but i am confused how can it possible historical date will run in current date for example hisorical date 6 mar 2021 and current date is 2 aug 2022. Please describe briefly.

That might b UTC time and my laptop time is ist
Thank You so much
Welcome 😊
how can you run tumbling trigger for historical data? I mean those dates will never come again
Can we create a trigger in AdF From other application like SAP. A trigger from SAP to ADF PIPE LINE Can you shed some light please
Total how many windows can open maximum?
Where can we get the ppt of this?
can we copy files in aws S3 to azure blob using tumbling window using adf ? Please can you advise ?
yes
if max concurrency is 50, then once it starts execution, lets say 1 window trigger is finished first & rest 49 triggers are still work in progress. In that case, will it wait until all rest 49 triggers are finished? or it will automatically start 51st trigger?
It will start automatically next one
Can you please share the PPT in your Git hub library
Thankyou sir
CAN I GET THE PPT IN THIS VIDEO

okay
Fully confused....there is no clarification
