Explained so neatly. I watched 3 videos before watching this and though I was not able to understand but this video made me understand the topic logically which, I guess, I'll never forget. Thank you so much.
How does a transaction T know that there is a Write-TS after T (read)? And what if there is a valid write, will it abort in all cases when there is a write after read?
but if TS(Ti) = w TS(x) then overwiting is allowed its also mentioned in silbertz book, but I don't know why its allowed. arent we overwriting concurrent txns write which might lead to issue.

Firstly thanks! My question is what will happen if 2 or more transactions have same time stamp????
not possible
woooow amazing explanation. it is completely clear.
What a clear explanation ! Thanks a lot.
but if TS(Ti) = w TS(x) then overwiting is allowed its also mentioned in silbertz book, but I don't know why its allowed. arent we overwriting concurrent txns write which might lead to issue.
That was truly amazing. I never understood it until I saw your videos.
very well explained......thank you!
that's very good , tricky explaination
best explanation... thank you!
Good explanation
Nicely explained.
What if transaction t0 having lesser time stamp fails then the read performed by t2 is a dirty read right
Is timestamp of youngest transaction == timestamp of the transaction which completed the latest write or read ?
yes
@@lokeshkadiyala9862 No, it's not. It's that transaction which has the highest timestamp value.
thanks..😃😃
can u please explain validation protocol
THANKS!!!
is that an n or x
Thanks for sharing but it's not complete. You forgot to teach read_in_transit and write_in_transit variables.
reference book name?
conservative timestamp?
Rishi Kambil Exactly! I'm searching for the same bruh!🔥
very confusing.. can not clear my concept...
First you say youngest at 6:30 and then say latest at 8:11
They both mean the same thing.
Nice explanation.
Good explanation.
