NICE SIR

[@rajasdataengineering7585]

Keep watching!

[@TomaszBI]

Well explained. Does snapshots contains whole data? I mean If you would delete a row in one version, would it still be possible to go back?

[@rajasdataengineering7585]

Thank you. Yes it is possible to go back

[@muruganandhams7834]

Sir, Are you taking any online class on AZURE Data Engineer

[@rajunaik8803]

Hi Raja, is there any upper limit for timestamp or version to do the time travel ?

[@rajasdataengineering7585]

Hi Raju, good question. As long as old files are available, time travel can be performed. Vacuum command deletes the inactive old files by default for 7 days. If vacuum command not executed and old files are available, time travel can be performed

[@horrorstory_10]

can i disable this feature of time travel so no one can retrive previous version of table

[@robingarg8391]

Use vacuum
