I have 1 question, at 6:25 you have mentioned 1core = 2vcPU, But at 43:00 You mentioned 4core = 4vCPU means 1core = 1vCPU. Can you please clear that for me. Thanks
if it is onpremises 1 core = 2 Vcpu if it is cloud everything is Vcpu. if it is showing as 1 cpu means 1vcpu in cloud. And note: some cores can have 1 Thread and come cores can have 2 threads. just check intel documentation. u will get more clarity
core vs vCPU depends on 2 factors.(for VMs) 1) Hyper-Threading support of CPU 2) Virtualization Platform ex : for Quad-core CPU scenario - CPU supports Hyper-Threading and you are using modern Virtualization Platform (e.g., VMware, VirtualBox, Hyper-V, KVM) then No of cores - 4 No of threads - 4*2 = 8 (Hyper threading means 1 Core = 2 Threads) No of Vcpus - 1 per each thread - so total 8 Scenario - CPU supports Hyper-Threading or you are a Virtualization Platform that does not support Hyper-Threading (could n't find examples) then No of cores - 4 No of threads - 4*1 = 4 No of Vcpus - 4
I am from US having 25 years exp. New to spark. Excellent session. Only question is what is databricks to do with spark here? Also is there a tutorial explain various topics within databricks (hive, spark, cluster, et...) Thank you
Very well explained
excellent video. thanks for sharing sir
Thank you 👍
Amazingly Explained..!!!
Thank you 👍
explication belle, claire, concise et nette. Merci frère
Good explanation about spark core. Thanks 👍🏻
Thanks for the spark videos
Thank you so much for the explanation. You have explained in so much detail and with so much clarity. This will definitely help everyone.
Nice explanation Bro..Thanks for sharing
Thank you 👍
@@TRRaveendra Thank you very much! Can you share with us the documents in pdf or word? Thank you.
loved it!
Thank You Sir, Your Explanation is Fabulous...
🙏
Thank you
Clear explanation. Thankyou!!
THANKYOU SIR , THIS WAS WHAT I NEEDED
Thanks
thanks brother its really helped for beginner's
Thanks you sir very nice explained... Please share any live session to meeting 🤝
Helped my interview .thanks ❤
thank you. All the best.
If we have 4 cores then 8 task can run in parallel right ?

core vs vCPU depends on 2 factors.(for VMs)
1) Hyper-Threading support of CPU
2) Virtualization Platform
ex : for Quad-core CPU
scenario - CPU supports Hyper-Threading and you are using modern Virtualization Platform (e.g., VMware, VirtualBox, Hyper-V, KVM) then
No of cores - 4
No of threads - 4*2 = 8 (Hyper threading means 1 Core = 2 Threads)
No of Vcpus - 1 per each thread - so total 8
Scenario - CPU supports Hyper-Threading or you are a Virtualization Platform that does not support Hyper-Threading (could n't find examples) then
No of cores - 4
No of threads - 4*1 = 4
No of Vcpus - 4
Hi can you please please make video of spark executor memory calculation in depth
but why to create an rdd

Spark is the underlying distributed computing system that Databricks runs on top of
