Hello, thank you a lot for making this video material. They are great. I have failed my first attempt to pass the snowpro core certification exam, now I have 1 week to study again. And that's the reason how I found your videos. I will watch all of them before taking it again. I hope I can pass the second attempt.
Glad you think so! I have currently 3 courses live, find the link below.. for now .. all of them are available in discounted price... www.udemy.com/course/automatic-data-ingestion-using-snowflake-snowpark-python-api/?couponCode=NEW-YEAR-2024 www.udemy.com/course/snowpark-python-ingest-json-data-automatically-in-snowflake/?couponCode=NEW-YEAR-2024 www.udemy.com/course/snowflake-dynamic-table-masterclass-e2e-data-pipeline/?couponCode=AC7896594913CDFA6155
First of all, amazing tutorial, I"m a Databricks user and this video is very helpful for me, thanks!. Correct me if I'm wrong but on 18:49 that CRON setup would mean that the task will run at minute 5 past every hour from 9 through 17 on Sunday (9:05,10:05,11:05,...17:05) instead of every 5 minutes. I think 5 minutes would be something like */5 9-17 * * SUN (9:05,9:10, 9:15,...17:05).
I need to check once again as this content was created long back.. but you have a point.. I would suggest try it out and experience it. Thanks for your note..
to run A & B parallel, you need to make both of them child a dummy task..that may not have anything.. but just select current_database() as sql statement.. so fork is possible... if join is possible or not... I need to check... it was not possible .. but I heard that snowflake made some changes in task tree design.. but need to check..
Very informative session, I love the way you articulate it.. I definitely recommend it to anyone who is interested in learning snowflake and it’s insights

Hi Sir, I am preparing for Snowpro Certification by seeing your video playlist, very useful and informative. Snowpro is showing as function created while creating procedure becoz procedure created with return boolean that is applicable for function.
I would request you to watch ch-21 UDFs or Functions - ua-cam.com/video/xnjCbgu0Qj4/v-deo.html Stored Procedure - ua-cam.com/video/CsH2sB6gwlw/v-deo.html
you can do it.. but if the root task is running, then you can not resume the child task.. if you try doing it.. it will throw error... (root/parent does not know if it has a child task, so it can be resume.. but if root/parent is resumed, child can not be attached or resume)...
Very Nice Series.Truly SF made simple. I have a question. we know task can be run periodically after a specific interval but can we schedule a task to begin from a future timestamp say from 01-04-2022 16:00 and repeat every 1hr after that? Does it support start time scheduling?
Never thought of this scenario, let me think and come back to you. There is no direct way in snowflake to serve this use case in snowflake and there are many control table approach where, either task is activated only after 01-Apr. But a good use case and I will surely investigate and let you know if I find a good solutions. And Yes, thank you 🙏 @Ameya for watching my video and your word of appreciation really means a lot to me.
I have a table with 4 insert statements but last 2 rows should be insert after 2 minutes of initial 2 insert. Can we create a task for that and if we can do so how to suspend the task once insertion is done otherwise it will keep inserting the last 2 rows after every 2 mins??
Got a doubt. In industry, Are the companies using any tools to implement data load logics including data cleansing , modifying additive fields, etc ? If so suggest me one or two tools ?
Please let me know when you are going to release all the lectures. I am preparing for the snowpro certification it would very helpful if you release the all the lectures. Thank you for providing such a quality contain for free
does task depend on more than one task , just like how a task is having child task ? how this scenario works? As I saw a flow chart in snowflake task doc having root task to update customer task, update product task which are acting as a parent to sales fact table ?
yes, it is possible.. the newer version of snowflake supports that..and you can check it in my end to end project ua-cam.com/video/qDmqE89DSQQ/v-deo.html
I did not get when you say "Validation".. task object in snowflake is a handler which can invoke a single SQL or a stored procedure and you can do anything as long as it is a call to SQL statement or a stored procedure. There is no specific limitation. Feel free to post your query to my insta account (instagram.com/learn_dataengineering/) Thanks for your note.
Loved your question.. First class entity in programminng world - An entity that can be constructed at run-time, passed as a parameter, returned from a function, or assigned into a variable. So in the context of this video, most of the action can be done using SQL statement or via scripting way...
I think your description of the cron timing might be incorrect. You state that `5 9-17 * * SUN` will run every 5 minutes between 9 and 17, but what this really says is that it will run at HH:05 between 9 and 17 - so at 9:05, 10:05, 11:05, etc. To get the every 5 minutes that you mention, I think you would need `0/5 9-17 * * SUN`
Task can be Created by SysAdmin role but resuming the task has to happen from Account Admin role , can you please tell us what is the reason for this behaviour ? since a role which creates a task should ideally be able to resume the same
You're welcome! ----- and yes, I know many of us are not fully aware of snowpark Python API, if you want to manage snowflake more programatically.. you can watch my paid contents (data + code available) .. many folks don't know the power of snowpark... these 2 videos... will help you to broaden your knowledge..

couple of SQL Script file link is not working as ch-17,ch-18,showing error file does not exist ,pls look into it and also for few chapter has not give SQL script link into description such ch-8,ch-9, could you please provide it ?
A task is limited to a single predecessor task; however, a task can have a maximum of 100 child tasks (i.e. other tasks that identify the task as a predecessor); in addition, a simple tree of tasks is limited to a maximum of 1000 tasks total (including the root task) in either a resumed or suspended state. Each parent task can have 100 child tasks-- this point is clear but what do you mean by "A simple tree of tasks is limited to a maximum of 1000 tasks total". Could you please explain this point in detailed way
Update : A DAG is limited to a maximum of 1000 tasks total (including the root task). A single task can have a maximum of 100 predecessor tasks and 100 child tasks.
Thanks for creating the course. Your content is more extensive and better than paid courses on udemy!

how was your re-take? any tips on clearing cert from your experience
Great content. The only channel I go to for snowflake.
The way you explain things are really "Simplified". Hats off to you man.
Thank you 🙏 for watching my video and sharing your feedback and your word of appreciation really means a lot to me.

I have Task A and Task B should be run in parallel after both the task completed I need to start the Child Task C. Is it possible?
to run A & B parallel, you need to make both of them child a dummy task..that may not have anything.. but just select current_database() as sql statement.. so fork is possible... if join is possible or not...

Nice. quick question. I am able to resume my parent tasks before I resum my child task. is it very new feature or bug or anything I missed?
you can do it.. but if the root task is running, then you can not resume the child task.. if you try doing it.. it will throw error... (root/parent does not know if it has a child task, so it can be resume.. but if root/parent is resumed, child can not be attached or resume)...
Great video, sir!
I just realized that Snowsight does include Graph representation on tasks, I believe it's a new feature recently included! :)
Thanks for the info!
Good work sir👍🏻 very informative video make more videos on snowflake

NICE.Do we have DAG ready as of date in snowflake . is it public or general usage?
yes...it is there..
you can watch my end to end data pipeline and it has also covered the DAG
ua-cam.com/video/qDmqE89DSQQ/v-deo.html
Your presentation is good as always.
Which software are you using for slideshow?
Glad you linked them... its standard presentation.. I use my personal template..
@@DataEngineering thank you . You mean is it PPT?
I am using video scribe for my videos..i do videos on visas and jobs. But videoscribe is costly.
Hi, how I can set up my task to start after a table update for Talend like a trigger?
I have a table with 4 insert statements but last 2 rows should be insert after 2 minutes of initial 2 insert.
Can we create a task for that and if we can do so how to suspend the task once insertion is done otherwise it will keep inserting the last 2 rows after every 2 mins??
Got a doubt. In industry, Are the companies using any tools to implement data load logics including data cleansing , modifying additive fields, etc ? If so suggest me one or two tools ?
The most popular is dbt and to onboard data.. it is fivetran (+dbt)
hello sir, you have used sequence object in this video, do you have a video explaining the sequence object
Yes, it is explained briefly in ch-07
Good content. In task now DAG of Tasks is added by Snowflake so please include that portion in this tutorial.
Thanks for your note.. I will review and will add in my future video.
Excellent
Thank you so much 😀
You can download this cheat sheet, that has detail for all the chapters.

Thank you for providing such a quality contain for free
will publish them soon.
@@DataEngineering thank you
Can snowcli tasks be scheduled?
you mean SnowSQL CLI.... if so.. yes, it can be done by any interface, Snow
does task depend on more than one task , just like how a task is having child task ? how this scenario works?

yes, it is possible.. the newer version of snowflake supports that..and you can check it in my end to end project
ua-cam.com/video/qDmqE89DSQQ/v-deo.html
@@DataEngineering thank you, I will go through.
can i use a validation using task !!
I did not get when you say "Validation".. task object in snowflake is a handler which can invoke a single SQL or a stored procedure and you can do anything as long as it is a call to SQL statement or a stored procedure.
There is no specific limitation. Feel free to post your query to my insta account (instagram.com/learn_dataengineering/)
Thanks for your note.
Can we setup a timeout for child task in dag?
as of now, no such feature.. may be snowflake will introduce it in future..
Now in Snowsight, we have ability to see hierarchal tasks in graphical display and please update video at 23:52.So folks can use feature.
wow..thanks for your note.. will try this..
Hello. I noticed t hat on this and the previous video #17, you used the term "First Class Object". What does that mean? Thanks.
Loved your question..
First class entity in programminng world - An entity that can be constructed at run-time, passed as a parameter, returned from a function, or assigned into a variable.
So in the context of this video, most of the action can be done using SQL statement or via scripting way...
I think your description of the cron timing might be incorrect. You state that `5 9-17 * * SUN` will run every 5 minutes between 9 and 17, but what this really says is that it will run at HH:05 between 9 and 17 - so at 9:05, 10:05, 11:05, etc. To get the every 5 minutes that you mention, I think you would need `0/5 9-17 * * SUN`
thanks for your note.. let me check
Task can be Created by SysAdmin role but resuming the task has to happen from Account Admin role , can you please tell us what is the reason for this behaviour ? since a role which creates a task should ideally be able to resume the same

Is someone else facing the same issue?
Just know I listed your Tasks video and very nice explanation. If possible can you cover a few real-time examples it's very useful to us?.

, Thank you so much for accepting my concern ji.
couple of SQL Script file link is not working as ch-17,ch-18,showing error file does not exist ,pls look into it and also for few chapter has not give SQL script link into description such ch-8,ch-9, could you please provide it ?
let me check and see if I can find the scripts and script link and fix it.
If we create a DAG in snowflake, and sub child task failed. Is there any way to rerun the failed task?
Sorry for the delayed response..when you say "redutn the failed task". what do you mean by it? More like Apache Oozie?
A task is limited to a single predecessor task; however, a task can have a maximum of 100 child tasks (i.e. other tasks that identify the task as a predecessor); in addition, a simple tree of tasks is limited to a maximum of 1000 tasks total (including the root task) in either a resumed or suspended state.
Each parent task can have 100 child tasks-- this point is clear
but what do you mean by "A simple tree of tasks is limited to a maximum of 1000 tasks total". Could you please explain this point in detailed way
when you create a workflow, you have multiple nodes and total nodes in a task tree should not exceed 1000.
Not able to access sql scripts. Says connection is not secure. Happens in every video
Update :
A DAG is limited to a maximum of 1000 tasks total (including the root task). A single task can have a maximum of 100 predecessor tasks and 100 child tasks.
thanks..
Can a child task have multiple parent task?
No. if you see the syntax, there is only one parent in the SQL syntax.
Not able to access SQL scripts
How to schedule a task every day at 10am? It should trigger only once for the day.
via cron, you can do it...
schedule = 'USING CRON * 10 * * '
# __________ minute (0-59)
# | ________ hour (0-23)
# | | ______ day of month (1-31, or L)
# | | | ____ month (1-12, JAN-DEC)
# | | | | _ day of week (0-6, SUN-SAT, or L)
# | | | | |
