[@NishaSharma-nd1dk]

Thanks sir g

[@aniket1015]

I really appreciate your wonderful work sir. THANK YOU for everything.

[@sivaranjaniduraisamy8766]

why are we allowing the write operation on t2? Because anyway that is also not required. The final value should be what t3 writes right?

[@AllRounder-q9g]

Very good explanation

[@vipingautam1257]

sanchit sir lecture was amazinggg

[@umairalvi7382]

Excellent explanation sir.

[@KNOWLEDGEGATE_kg]

Thank you so much, It would be great if you give us a review on our app play.google.com/store/apps/details?id=in.knowledgegate.www. It will help new audience to build trust on us 😀

[@chakshujain7557]

At 10:29, Sir, why W1(Q) is blind write as T1 is reading then writing. I think only W2(Q) and W3(Q) is blind write? Kindly correct if I am wrong.

[@prayagkhurana4499]

correct!! and by the way it can write without any problem bcoz t1 is writting after t2 performed write ysss plzz explain??

[@anonymousdrake1704]

@@prayagkhurana4499 Time stamping k according T1 ko rollback krna chahiye tha(kyunki vo apne time slot se baad aaya dubara write operation perform krne)...but uski baad mei value T3 ne override kr deni thi...toh hmne Thomas Write Rule k accordingT1 ki write value ignore krdi saare T1 transaction ko rollback krne se acha...

[@lakshsinghania]

@@anonymousdrake1704 hnji sahi baat boli

[@gouravsisodiya8304]

​@@anonymousdrake1704but T1 transaction ko T3 se kya matlab ? T3 to abhi tak system me aayi nhi h... Han T2 ki wajah se T1 rollback hoti ya T1 write skip hota... But T3 ko to koi role nhi samjh aaya.....

[@aayush5474]

Even if there are blind writes it does not mean that schedule is view serialuzable. Polygraph is used in this case.

[@Tanush-od5nj]

bro can you explain how this transaction is view serializable

[@Arjit_IITH]

Very Nice Video Sir. Keep Posting!

[@radiagulzan]

thaaank youuu!!!

You're welcome.. Keep learning !!

[@shashankrustagi2812]

If you would have made this video before GATE 2019, I would have believed ki how u think, and we all would have gotten 2 marks for that question on Thomas write rule.

[@gouravkhator4169]

[@vinayaksharma-ys3ip]

[@meghanajwala2971]

in the 3 transactions example, what if w(Q) of T1 was the last operation and w(Q) of T3 didn't exist only or was there before T1's w(Q). do we still ignore it?
