Sijie Guo resolved BOOKKEEPER-223.
----------------------------------
Resolution: Won't Do
Fix Version/s: (was: 4.5.0)
There is already an listener based pending read op, which it calls the callback
individually. it doesn't really meet all the requirement here, but it serves
some purpose.
> PendingReadOp tries to read all entries at once

> Issue Type: Bug
> Components: bookkeeper-client
> Reporter: Ivan Kelly
> Assignee: Ivan Kelly
>
> PendingReadOp tries to read all entries from the bookie ensemble at once, and
> fill an enumeration with what comes back. This is bad. If we have a ledger
> with millions of entries, and you try to read the whole thing, you're client
> will crap out. Of course you can get around this by only requesting a little
> bit at a time, but why doesn't the client do this for you, as we are
> effectively exposing a iterator interface anyhow?
