Whitney Sorenson commented on BOOKKEEPER-257:
---------------------------------------------
I need ledger ids for a different reason; simply:
I have multiple writers writing multiple ledgers.
I have separate readers reading those ledgers.
I don't want to maintain state between them about what the list of all ledgers
are, since BK already has this state.
I am currently using some gross code that reads the ledgers directly from ZK.

> Key: BOOKKEEPER-257
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-257
> Project: Bookkeeper
> Issue Type: New Feature
> Reporter: Ivan Kelly
> Fix For: 4.3.0
>
>
> When an application is using bookkeeper it must keep a copy of the ledger ids
> it creates so that they can be used later, and once they are no longer
> useful, deleted. However, in the case of a crash between ledger creation and
> persisting the application copy of the id, the ledger will be dangling.
> Therefore I propose we have the ability to get a list of all ledger ids,
> which clients can use for garbage collection. However, I don't think it
> should be part of the BookKeeper class, rather part of a new BookKeeperAdmin
> class.
