nit:
I see that Ev->Get()->GetPutStatus() is passing result to success.
I suggest considering the possibility of naming the variable not success but specifying the success of which operation is expected here.

Changelog entry
split actions:
on execute we have to write into db only
on complete we have to write to memory storage
in other way we have problem in case execution not finished, but gc finished before and if binary killed in this time, we have problem with meta withno blobs
