--------------------------------
Assignee: Matthieu Morel
> Optional recovery of expired and checkpointed PEs.
> --------------------------------------------------
>
> Key: S4-42
> URL: https://issues.apache.org/jira/browse/S4-42
> Project: Apache S4
> Issue Type: New Feature
> Affects Versions: 0.4
> Reporter: Matthieu Morel
> Assignee: Matthieu Morel
> Fix For: 0.4
>
>
> S4 provides a caching mechanism for PEs, and PEs can be assigned a time to
> live. After that time, the PE instance is removed from the cache and may be
> garbage collected.
> When combining with the checkpointing mechanism, expired but checkpointed PEs
> are restored from a former checkpoint.
> This may or may not be desired, depending on the use case. Therefore we must
> provide an option to restore - or not - the state of an expired but
> checkpointed PE.
