Data Import Handelr Question

[Yuval Dotan]

Hi
I want to use the DIH component in order to import data from old postgresql
DB.
I want to be able to recover from errors and crashes.
If an error occurs I should be able to restart and continue indexing from
where it stopped.
Is the DIH good enough for my requirements ?
If not is it possible to extend one of its classes in order to support the
recovery?
Thanks
Yuval
