Really Enjoying Thanks sirji

Sir pls provide the questions in description

If the column already exists then withcolumn update that col else it creates new column based on logic

How many have transitioned from other role to data engineering?.. that's more interesting and important

This is called explanation 😊

Are row_number values correct shown at 22:00 ? I mean if we are partitioning by marks, then how can output look as shown in the video?

The row_number values for marks are not correct (35:16). The correct output is: Marks Row_number 100 1 100 2 99 1 98 1 98 2 98 3 97 1 96 1 95 1

DAG-Direct Acyclic Graph which contains the RDD states after each transformation it is only triggered when an action is called, that gives you data lineage. Stop confusing yourself and others with made up stories. DAG is not a sequence of actions!

Sir konsa course Kiya tha enn sbb nee ? Fee's kitne ? Kitne months baad placement huve ? Course mode online tha ke offline ? Pls answer all this question one by one 😊 pls 🙏

SQL CHAMPIONSHIP PROGRAM ke baare me batav...

You are doing great work. Lot of respect

if i started learning for now than there are very less data engineering internships(if one has data internship it is easy to get a job ,and that person also get hand on experience ) ,,,,so should i do data analyst first only for internship and after that i will study for data engineering for job because it is also a good way , and i need to do an internship because it is in our college criteria , they do not support much if you do not have done internship?? "Congratulations on your well-deserved award! Your dedication and hard work have truly paid off"

Date format, sum case, group by Array max occured number

Solution for the first coding question is wrong , in both the loops they are incrementing the freq and also need to compare the length of both lists first , that'll be the base case

Reverse string on every occurrence of I letter Avg of logged time

Very nice content. Extremely useful

like i had faced lots of similar questions and tried to answers but i noted lot of points in her explanation , very helpful for me

Count the highest reportee for manager Tell all the class names who has atleast 5 students

String n col name manipulation

Users with max skills Remove space from col names Matrix using two list

Source type, project discussion Handling duplicates Delta lake feature Spark vs dbx Power bi connect to synapse Spark architecture Dag Client mode vs cluster mode Df vs dataset Normalisation 2nd highest salary in dep

This is amazing, very well explained Sumit Sir! Do you give career advice also?

Spark core -Rdd (flexible) high level apis- Df and Spark sql (easy to write query) Transformation n action Spark submit process Deployment modes Types of transformation Repartition n coalesce Methods for schema enforcement - ddl, struct Consecutive wins in sql

Java used in Hadoop Bound to work on mapreduce Can only work on batch process not real time in map reduce

Data lake vs delta lake Unity catalog Data profiling Data governance

Predicate pushdown What opt used in spark Transformation used Groupby n reduceby Faced oom error ? Salting Data skewness Data spillness Cache persists Lru Repartition vs coalesce Rnk densernk rno What happen submit spark job

I definitely learnt something. Thanks.🎉

first one Select name from salary_table as a where salary>(select salary from salary_table where id =a.managerid)

What is the answer to the last question - 'When we align transformations and action in a DAG, what is that graph called?'

Dear Sir, hope you are doing well, when can we expect the next video on Python? It's been more than 3 months now, that you haven't posted any followed video on Python. I guess everyone is eagerly waiting. Please post it asap. Thanks

sir please upload more videos. We are waiting for the next

interview Series are good , please upload remaining 10 questions , eagerly waiting sir

Master and slave architecture we have driver node acts master node multiple worker nodes submitted spark jobs contexts of spark node - create jobs and execute plan spark cluster entry point driver will request resource manager send back to driver also do iteration of jobs

Great questions....

The interview series is really helpful, Thank you
