what will be the case if we store two files(.csv) in same location then the if condition gives us two different names.

a very good video but dbutils does not seem to work on notebook in lakehouse fabric

@HanumanSagar Жыл бұрын

Hi Bro..Can we do copy directly like dbutils.fs.cp( source path to dest path)? Instead of using for loop and if condition?

@WafaStudies Жыл бұрын

Yes u can. But part file name we should get it first right? So we used for loop and if condition to get filename

Will it not degrade the performance while writing the dataframe?

Yes for large file it may cause driver failure, Coalesce will do shuffle and move it to one partition and then save it.. pandas will collect it to driver node and save it. If df size is large then it is not advisable to to save it under one file but if needed then yes for small files we can use.

@Vikasptl07 Жыл бұрын

Convert df to pandas df and save it as one file

@WafaStudies Жыл бұрын

Yes we can that too. I will cover this in next video 🙂

Pandas DF will be a Problem when the file size is huge as it always runs on a Single Node cluster .

Hi if I am doing same with parquet instead of CSV I am getting error like py4j security error any idea how to workaround this one

@RR.G 5 ай бұрын

I see this code is copying each csv file to a different name, but not creating a single csv file for all the data

This doesnt work for me in Synapse notebook. Getting below error. I am not sure we need to define any library for this. NameError: name 'dbutils' is not defined
