> When populating one single index or all indexes there is no recovery if something goes wrong. we may need to add error handling when populating indexes.
> the error handling may need to take place at 2 different levels:
> * at the index level when we create or populate a single index: if something goes wrong with populating the index we should go back to the initial state of the index table. (if empty maybe we can purgedata otherwise we can use snapshot)
> *and when we do populate all index the recovery may need to deal with all the updated indexes if something goes wrong. 
>    **One way to deal with it  is to restore all the indexes to their original state .  and the user can correct the issue and rerun the command again to populate al indexes
>    ** another way may be to restore only the index that caused the issue. and the user can correct the issue and then run the populate index on the remaining  index
