Hey, one thing about English - please guys correct me if I am wrong, but I am pretty sure what I am talking about - you shouldn't say inside a sentence "how does it work", but "what it works". Despite that, the content is awesome!

[@AdamMarczakYT]

You can if you ask a question. "How does it work" is a question structure, not a statement. it should be "how it works" if I'm stating a fact. You wrote "What it works" but I assume that's a typo. It's one of my common mistakes, my English teacher tries to fix it but it is still a common issue for me ;) Thanks for watching!

[@veerboot81]

Hi Adam, very nice work this, I made this for a client of mine and found out one important thing: within the For each not all blocks are executed as if they are working together atomically. What I mean is that if you start two thinks in parallel using the For Each block and within the for each block you have two blocks - say block A and B - connected using parameters (item()) within these blocks say X and Y. Block A starting with item X will not necessarily be using the item X in block B although connected! So I want to suggest one extra advice to use only one block in a For Each block at max if using parameterazed block within or if you need more than one block start a separate pipeline within the For Each block which will have the multiple blocks. These pipelines will be started as separate childs and to the work in the correct order. With kind regards, Jeroen

[@AdamMarczakYT]

Hey, not sure I understood what you meant here. Using parameters is not making any connection between the actions.

[@veerboot81]

@@AdamMarczakYT I'm using a for each loop to load tables with dynamic statements, if I need more than one block (like a logging call to sl server, a copy block to load the data and a logging block after being done with loading these blocks can be in the for each loop itself, but if you start in parallel multiple times different load of tables the blocks will not follow each other sequencially, but will be running through each other, so the logging will not belong to the copy block for example. I will see if I can make an example if I find the time. To solve this I start always another pipeline within the for each and put the blocks in this pipeline. This will create child pipelines in the for each loop ensuring the right order of execution of the blocks (logging start, copy and logging end)

[@AdamMarczakYT]

[@rubensanchez6366]

Very interesting video Adam. I found quite enlightening your idea of storing metadata. probably it could be maintained separately tracking last record loaded so we could use it as an input for delta loads through queries instead of reloading the full table on each run.

[@AdamMarczakYT]

You can either use watermark or change tracking patterns check this out docs.microsoft.com/en-us/azure/data-factory/tutorial-incremental-copy-overview?WT.mc_id=AZ-MVP-5003556

[@szymonzabiello2622]

Hey Adam. Great video! Two questions regarding the pipeline itself. 1. How do we approach Source Version Control of the pipeline? In SSIS we could export a package and commit to Git or use TFS. How do we approach versioning in Azure? 2. What is the approach to deploy this pipeline in upper environment? Assuming that this pipeline was created in dev, how do I approach deployment in i.e. UAT?

[@AdamMarczakYT]

I think this page describes and answers both of your questions. docs.microsoft.com/en-us/azure/data-factory/continuous-integration-deployment?WT.mc_id=AZ-MVP-5003556 thanks for watching :)

Very good explanation! I will try to read a list of tables but not export but do mask certain columns. I guess i have to use a derved column inside the for each loop maybe. Three parameters: schema_name, table_name and column_name. But how to make: update . set = sh2() where Key in (select Key from othertable) in a derived column Name context?

[@agnorpettersen]

I reseached and tried one thing. Seems to work. Have the lookup and foreach like this video and inside the loop i put the function. There I make an dynamic sql statement picking up the variables from the table i have in lookup.

[@feliperegis9989]

Hey Adam, awesome work and explanation! Do you have another video explaining how to deal with massive data copies from tables in bulk using ADF and that may resolve issues with maximum data or rows of data? Can you make a video with a demo explaining how to deal with this kind of scenarios that you mentioned that's the story for another day? Thanks a lot in advance!! =D

[@AdamMarczakYT]

Thanks. Well, Lookup shouldn't be used for data, but for metadata driven approach, so 5000 rows limit is very good here. It is rare when you will copy over 5000 tables/files with different structure)/etc. If you do you can do different techniques but in those cases I probably would shift approach entirely. Will think about this.

[@YenBui-dn2ek]

Thanks for your great video. Is there any limitation in terms of a number of tables, or table size when we use copy multiple in bulk according to your experience?

Very nice Adam !!! I didn't checked yet but do you have the process reading from blob storage the csv files and transfered the data to the table ? If you have it can you pls provide the link ?

[@AdamMarczakYT]

Hey, thank you. I didn't make video on reversed scenario as I thought it might be too similar to this one. Just use Get Metadata instead of lookup to get the list of files and upload them to a table. Note that for this to work files or paths should contain the name of the table so you know which file goes to which table. :)

Excellent. Well, in this case replace lookup with Web Activity and query table storage rest api docs.microsoft.com/en-us/rest/api/storageservices/query-tables?WT.mc_id=AZ-MVP-5003556 and loop over the response.

[@Dadwalfamilyadventures]

Hi Adam, this is awesome session. One question: Where in Azure documentation I can find the information regarding all possible output variable of a given activity e.g. when you were explaining about lookup activity, you talked about the property "firstrow". Where can I find such properties supported by all activities in Azure documentation ?

[@AdamMarczakYT]

Thanks! For details always check the docs by googling "ADF action". For lookup this would pop up which explains everything you asked docs.microsoft.com/en-us/azure/data-factory/control-flow-lookup-activity

[@shruthil7913]

Hi Adam, there is a way to copy in different tables in SQL. (Example : car csv to cars SQL table and Plane csv to plane csv table automatically, without manual intervention.

Hi there. Well this video is all about it, just reverse the order and use GetMetadata for blob storage action instead of the Lookup :)
