I am using Synapse. As you mentioned, ADF is integrated into that. I am able to replicate your demos in Synapse Analytic. Thanks. Good job !

Is DQ stand for data quality in synapse big data? What is BG DQ?

[@ranjansrivastava9256]

Dear Maheer, Really very Informative Video. Could you please prepare one video for the Data Reconciliation in ADF the way you have created and from there we can able to send email to the customer or stakeholder like we have checked the data quality before sharing the report to the customers. Really appreciable for that.

How did I miss this video.. This is amazing 😊 Thanks

[@WafaStudies]

Thank you 😊

[@sumanyarlagadda6271]

The shortcut to a clear-cut explanation is your knowledge sharing videos on ADF. Great to follow your channel or playlist. Thank you so much🙇 🎆

[@WafaStudies]

Thank you for your kind words ☺️

[@sonamkori8169]

Thank You sooo much for wonderful explanation.

Hi ,how can we get updated records as part of incremental load ?

[@srikanthreddy8779]

It is helpful for my scenario..

[@WafaStudies]

Thank you ☺️

which ETL tool can I use to compare data between on-prem SSMS and ADLS gen 2

[@durgalakshmi3213]

hi..so when u add the sink at the last, will only the new column get added ?

[@ayocs2]

hello sir, is it appropriate to use Exists against two database source (SQL Server and Postgres)
i want to insert only the non existing rows from one database to another
and also to note that I've to do this on production data; and sink is postgres

[@guddu11000]

how to exculde column from columns function, lets say 1 have 5 columns and want to use just 4 column but don't want to select individual column rather i want to use column() funtion and exculde a columnfrom it

[@SushilChauhan]

remove it from mapping

[@NeumsFor9]

When I have a small column set like this, I like to concatenate a delimiter to minimize collisions as a safe practice. Been burned before whwn not using it.

[@akashsharma4769]

Hello sir. Firstly I wanna thank you for this amazing series on adf it's been helping a lot. Sir , will you be adding more real world scenarios to this playlist or its the end of this series.

Is data quality DQ in analytics? What is BG DQ

[@srinivasarao416]

Hi Brother, it is just like SCD2 . shall we use same SCD2 logic here. Please let me know

[@ksnaveenkumar1]

Have you tried this approach with large volume of data? I am curious to see the performance with large datasets.

[@CoolGuy]

If the volume is large, use ADB.

[@sunilpandey7197]

Hi Maheer, Thank you for good quality videos on Azure!
Could you please help me with the following:
1. I need to test two Azure SQL DB's -
- Need to compare if all the data rows are same, give output if there are any different rows or missing rows in the target DB table
2. All general ETL sceanrios - Schema, tables count, table data etc.
3. Transformation testing - if the table has any transoformation then test it on the target Azure DB table w.r.t to Source Table
Overall idea is to to proper ETL testing
Please let me know if that's possible? If yes, then please point me right direction by providing some links or reference to go through?
Regards,
Sunil

how to replace a null records in a table with someother value using ADF?

[@WafaStudies]

U can use dataflows for this. Use derived column transformation

[@spranavshanker]

Can you please create this scenario using pipeline and activity, without using mapping dataflow. I think this will not be best approach with large data and costlier.

[@mankaransaggu15]

hi sir .. how we can connect with you.... need some help with a use case

[@NaveenKumar-kb2fm]

Can you please do the same using ADB and post it

[@hnii99]

Good work bro 👍

[@WafaStudies]

Thank you 😊

[@harithad1757]

Too good

Thank you ☺️

Sir, please make a video on Incremental Data Loading Using ADF and Change Tracking for multiple tables.

[@maheshreddy732]

did u get any info on this Multiple tables?

[@sunilveerendravattikuti3848]

Hi Maheer,
I have a query here. If I use exist transformation(does not exist rows) directly without using any other transformation before. I think we will get the same result right? Pls clarify. Thanks.

[@WafaStudies]

In that case for condition inside exists u need to add multiple conditions for multiple columns and to check. Instead generating one unique column(hash) based on all columns and then using that inside condition is best way.

[@sunilveerendravattikuti3848]

@@WafaStudies yeah. Thanks Maheer.

[@Ankita_ki_Art]

Great
