Whenever I watch lectures on some other KZbin channel, it makes me mentally tired within an hour since I have to comprehend the core concept of the video myself as they usually provide only shallow explanation. But your simplistic examples of these concepts make me feel that I am learning effortlessly and hence, I can watch your videos for hours. thank you so much sir.

[@subhradeepbiswas51]

Hi Sanchit, 1st of all thank u so much for your effort. Its been truly helpful. One question though, is it always true that T2 will read the value of A from local buffer (which has been altered by T1 in your example) ? Asking this because, uncommitted values r not visible to other sessions, right? Can u plz clarify? Thanks again for ur help.

These are the problems caused by concurrency that's why we use the concept of isolation

How will transaction t2 know that a failure occurred in t1?

[@gauravraj2604]

videos of multi level indexing like B Tree, B+ Tree are not available ? Need your help Sir.

[@coppercu9335]

Hi Gaurav bhaiya

[@gauravraj2604]

jante h hum tmko?

[@Gokuda]

Sir , you said that committing of T2 should be done after the T1 , so my question is that is this just commit the part which needs to be done by T2 after T1 or there must be a read R(A) after T1 commits because if T2 is not reading the value of A then whats the sense in committing after T1

[@ganapatibiswas5858]

Example in the beginning sums up the whole dirty read problem....

[@devlowanshi3820]

Amazing

[@akv169]

sir why there is a need for a txn2 to take value from txn1 , txn 2 can take its own value to read

[@VishalThakur-hv6qd]

so sir in that case (solution of dirty ready) . The waiting and respose time will be increase for T2 transaction . if someone know please reply.

[@souravsingh763]

It mean traction in happening on same device at same time as you mentioned local buffer RAM

[@vinayaksharma-ys3ip]

💯💯👍

[@sajalagrawal1430]

sir u rocks

[@Shivam-kz2dg]

One doubt : even if T2 is committing after t1 still how will T2 come to know that t1 has rollbacked or the answer T2 copied was wrong ? As there is logical isolation then t1 rollbacked will not tell T2 to rollback as well so how is T2 committing after t1 has committed , a solution to dirty read problem?
