Hi Shubham, Great content, I am following your series in data bricks environment. When we read a file it generates a job to get the metadata, when I to check the execution metrics in databricks ui, it does not show inputsize/record in databricks but in your docker container it show, where can we check that info in databricks?

3:00 what do you mean by identifying the metadata? what's the use of it in this context?

@easewithdata 2 месяца назад

Metdata means the information about the column names and their datatypes

Can you please do it in databricks

@easewithdata 9 месяцев назад

Hello, You can lift and shift the same code in Databricks and it will work. Only difference, you dont need to generate Spark Session in Databricks notebook, it generates one for you. Hope this helps.
