Azure Databricks Learning: Databricks and Pyspark: AutoLoader: Incremental Data Load
=====================================================================================
AutoLoader in Databricks is a crucial feature that streamlines the process of ingesting and processing large volumes of data efficiently. This automated data loading mechanism is instrumental for real-time or near-real-time data pipelines, allowing organizations to keep their data lakes up-to-date with minimal manual intervention. By automatically detecting and loading new or modified files from cloud storage, AutoLoader enhances data engineers' productivity, reduces latency in data availability, and ensures data accuracy. It plays a pivotal role in enabling timely insights and analytics, making it an indispensable component in modern data architectures.

Thanks for the amazing video I'm trying to load 4 years worth of historical data with around a 1 million files per day I tried to use autoloader and it's taking 1 day to load just 22 hours worth of data Using directory listing method Can you give me some recommendations to load this data as fast as possible

Exellent. I have one question. Most of the time Interviewer ask on SchemaEvolution what is the ideal option to tell among those four you mentioned or its depend on type of data and type of processing you do.

sorry, one more question related to autoloader. In case if a databricks notebook is moved converted to be run on EMR cluster, does the autoloader equivalent compatible feature exists on EMR side? Asking because I believe autoloader is databricks specific feature
@rajasdataengineering7585
@rajasdataengineering7585 4 месяца назад
Yes that's right. Autoloader is specific to databricks, not spark. So EMR cluster can't support auto loader

Hi Raja, I am getting an error in azure databricks interactive cluster as driver is up but unresponsive likely due to GC. Any idea how to solve this issue ? Can we increase heap memory for this issue ?

Can you please make a video on Job creation how to configure variables\parameters using notebook to deploy one environment to another environment (i.e. Dev to UAT or UAT to Prod) ? Also, make a video on custom logging mechanism to capture the success\failure for each notebook? if you share these it will be helpful.

Hello Sir. i am very much confused. I want to know how people used to apply incremental load in azure DE when autoloader was not there. Please create a video on that. Untill and unless we know about the old method we cant understand the solved Problem. How company used to follow upsert in azure de when data used to keep on changing.?
@rajasdataengineering7585
@rajasdataengineering7585 7 месяцев назад
Hi Prabhat, DE projects used to follow bunch of old methods and I have covered few of them in this video before getting into auto loader. One of the common approach was water mark method

Hello again i have same question i understood using watermark we loaded new data to landing...how can feed the new files to bronze, shall we read whole folder through spark read api. suppose cust1.csv came on first day and cust2.csv came on second day...same goes on for third file as well. so how people used to read the latest file here...we cant directly read third day file bcoz we need to make it dynamic to read latest file so that it could feed it to bronze.Please do answer here@@rajasdataengineering7585
