@soumilshah thanks for your informative video, but the link you have given in description for pdf files is not working. could you please update that with right url.
Thank you for the video. I have a question on precombine field.Why is precombine field required for upsert and delete operaton even if there is primary key?
One doubt though why do we have 2 tables for MoR and only one table for CoR. What are the use cases for each of these modes? Do they both support all CRUD operations?
MOR gives you two table read optimized and real time. Remember in MOR the RO table gets updated after set number of commits remember as I mentioned the merge happens while reading COW you only have one table and merge happens while you write the data Again they are both meant for specific use cases depending upon what your application need Read or write latency based on that you may decide to go with either
Hi Soumil! Congrats for an excellent video. I have a question, do you know what permissions are required in IAM policy instead of using the admin permissions?
Hi , great videos, but do you have any video for a lambda python code to bulk insert and upsert data into data lake in a hudi table in parquet format? it is crazy I cannot find anything, pyspark is giving me a lot of java errors :( thanks in advance :)
Thanks, Soumil. Great starter! I have some questions: How big is the dataset? select after update took about 8 secs and the delete took 8 mins. Is it normal? It sounds quite slow. How does Hudi compare to iceberg and deltalake in terms performance, in your experience?
It depends there are lot of parameters that’s you can tune Ru using indexes ? Ru using partition Did you use right table type for application Are you using cleaner utility Are you using clustering ?
Hi Soumil - Great video. I have a question, you have mentioned that RO will perform merge depending on the condition - So what is the default condition it will have when we don't specify any conditions. Will it never update the changes?
Any of you face the issue with delete command? After running I cannot longer querty the RT table, and the asset is not being removed. Athena complains about GENERIC_INTERNAL_ERROR: org/objenesis/strategy/InstantiatorStrategy
Thanks yes there is open ticket This is known issue on aws side I will send you ticket where you can watch status github.com/apache/hudi/issues/7430#issuecomment-1373626282 Please note this only occurs for MOR tables
FYI people who see error
Make sure you remove a frok s3 path
Instead of s3a:// use s3://
great video covering comprehensively all major features which a beginner should know on Hudi. Thanks Soumil for taking time to make such videos
omg I enjoyed watching it... great job 👏all my concepts brush ups for interviews. It was so much detailed and you made it easy :)
Great Video!!!! Lot of learning through your Channel always !!!!
Glad to hear it!
you're doing great work. Really appreciate the knowledge you shared .🤝🏻

El código no me esta funcionando me dice que se tiene que crear una base de datos, me ayudas
Soumil can you please share the slides link which you were showing in the video.

I just started i was tryjng to download the pdf for steps to be perform but it us not accessible can you please share the new link
Great video. Love the hands on lab material!
Hi Soumil! Congrats for an excellent video. I have a question, do you know what permissions are required in IAM policy instead of using the admin permissions?
You're doing and amanzing job! I have just one doubt, why at this video the connector was not necessary as I saw it was used in the other videos?
Hi , great videos, but do you have any video for a lambda python code to bulk insert and upsert data into data lake in a hudi table in parquet format? it is crazy I cannot find anything, pyspark is giving me a lot of java errors :( thanks in advance :)
but why do you want to use lambda for ETL kind of work . Lambda is supposed to be used for tiny jobs and not bulk inserts and updates.
Pdf is not available 😢

It depends there are lot of parameters that’s you can tune
Ru using indexes ?
Ru using partition
Did you use right table type for application
Are you using cleaner utility
Are you using clustering ?

It happen after set commit
I don’t know exact number need to refer docs
gdrive link is not working please check
I am getting error that cannot sync using meta sync class HiveSyncTool.. Can you please tell me why does this error occur?
Did you use the code I provided ??
@@SoumilShah Thanks, The issue got fixed.
Hi@@pragattiwari5530 How did you solve this? I'm still getting this error
I'm getting the same error even though I have literally copied the code by @SoumilShah. @pragattiwari5530 how did you fix it?
