Hi, 

*Context* : I have a hierarchy wherein a parent (few levels below root) is 
a persistent-actor (let us call this as partition-manager (this Id is 
ensured to be unique). It starts few child actors which are again 
persistent (let us call them as partition-handler-X where X is some unique 
number to ensure uniqueness of persistence-id). In addition to 
partition-handler-X, 
partition-manager also spawns few regular non-persistent actors

Above scheme works without any issues. 

*Problem* : Off late we encountered a situation wherein there are very 
sporadic journal-write failures (using LevelDB plugin). Write-failure may 
as well be triggered by an environment issue. While we are investigating 
the same, I also intend to have a level of protection at the actors' level 
to use Backoff supervision strategy

*Clarification* : Is it advisable to use Backoff supervisor strategy for 
partition-manager 
(parent) as well as partition-handler-X (children) persistent-actors to 
cope with sporadic journal-write failures without disturbing any other 
actors of same hierarchy ?

Regards
Muthu
