Thanks for the detailed explanation. When trying I am getting only two partitions out of which one file size is zero and the other one is the full file (where the split was for 4 when calculated). Could you please help me sort the issue as where I went wrong?
Hi, Thank your for this video, very helpful. Quick question: how can I set up the dataflow in order to have only the first file with the header and the other ones with only the data please ? I need to split a file into chunks before sending it through API and thus i need to have only the first file with the header. Thanks !
hi Thank you so much for explanation can you please tell me that now my datasets are partitioned then how can i now use these portioned datasets in my transformation in my databricks notebook? how can now load this split datasets? in SCALA
@All About BI! Hi Maam, What if my JSON file has 4 GB in ADLS and wants to load the data into SQL DB, Do you recommend the same process - where it creates around 4000 files and loads using DF? please advise the best solution to achieve it. I tried large clusters with memory-optimized, partitions but had no luck. DF is failing due to OOM. Pls suggest.
So I have .gz file which is 20gb in sftp.. I want it into ADLS as it is as a .gz file.. with this approach I can partition it and then how do I compress it back?
Hi.. Anybody faced duplicate issue..? The source file is being splitted as expected, but one or few splitted files have duplicate records.. i have cross checked, there is no issue in source file..
Just one question - lets say I split a file which contains the fact table data into 5 files. When I load the data from DataLake to SQL DW, how the splitting would help?
@@AllAboutBI My apologies, I'm not clear. Lets say you break a fact csv into 6 csvs. So while you load to DW fact table, you'll be using a FOREACH loop and eventually it'll be loading sequentially
@@rajeevsharma2664 no, no need to use foreach .. make ur data flow source to point to the folder where the files are present like, output/*.CSV.. By giving wildcard file name, data flow will load all matching files in parallel
Hi mam, I am trying to apply same scenario, but while validation I m getting error as "linked service with self hosted integration runtime is not supported in data flow"
Ya thank you.. that issue is resolved.. but now my files are not splitting in same size.. I have 34 MB file if I split file size is diff.. how to deal with it..
@@AllAboutBI as I can't load more than 16 mb file in snowflake table.. in a single column.. so I tried your way but one file is splitted and generated with 17 mb size..
keep it up, very good series. really enjoying it. i am learning ADF
Thanks dorgeswati!
@Titan Forest Try flixzone. You can find it by googling :)
Very good explanation
Thanks for sharing knowledge
Welcome 🙏
Hi,
Thanks for posting this video.
Can you please clarify how you ensured the files were split by country?
Good Interview Question might be.How to do an incremental data processing in azure data factory or data bricks if the file size is large

Glad to hear that
A good video ! How do we partition the file by date instead of size ?
May be you have to check this ua-cam.com/video/hVfGr8AD35I/v-deo.html

Hi mam,can you please help understand how the data in the same files distributed?? How to we identify what data is available in which files
Can u show a scenario to copy only a set of fields from tables(say 10 columns data from overall 20 columns) in SQL into ADLS as csv files
So I have .gz file which is 20gb in sftp.. I want it into ADLS as it is as a .gz file.. with this approach I can partition it and then how do I compress it back?
Can it be done without using data flow?
Hi Ma’am if we have multiple datasets in a single file how do we split the file into individual dataset
Is this one applicable for Database to Database ?
Without Dataflows how can we do . Can you please explain
Super thank you : )
Can we split large xml files also into smaller xml files.

.json - files

can we split large parquet file into small parquet files using same method ?
Yes aditi
Very nice
Thanks mam

Data flow can point to the folder which has the split files. It can load all files parallely.

Hey, as the error says, you can't connect to an on prem data store inside data flow
