nope. this patch introduces a way to paginate results via #getRange. this
option is no longer needed.

> We rely on E/PStore interfaces to persist data. Even though E/PStore stands
> for Ephemeral and Persistent stores respectively, the current design for
> EStore does not extend the interface/functionality of PStore at all, which
> hints abstraction for EStore is redundant. This issue proposes a new unified
> Store interface replacing the old E/PStore that exposes an additional method
> that report persistence level as follows:
> {code:title=Store interface}
> interface Store<V> {
> StoreMode getMode();
> V get(String key);
> ...
> }
> enum StoreMode {
> EPHEMERAL,
> PERSISTENT,
> ...
> }
> {code}
> The new design brings in less redundancy, more centralized code, ease to
> reason and maintain.
