> Need procedure to garbage collect ledgers
> -----------------------------------------

> Key: ZOOKEEPER-464
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-464
> Project: Zookeeper
> Issue Type: New Feature
> Components: contrib-bookkeeper
> Reporter: Flavio Paiva Junqueira
> Assignee: Erwin Tam
> Fix For: 3.4.0
>
> Attachments: ZOOKEEPER-464.patch, ZOOKEEPER-464.patch

>
> An application using BookKeeper is likely to use a large number of ledgers
> over time. Such an application might not need all ledgers created over time
> and might want to delete some of these ledgers to free up some space on
> bookies. The idea of this jira is to implement a procedure that enables an
> application to garbage-collect unwanted ledgers.
> To garbage-collect a ledger, we need to delete the ledger metadata on
> ZooKeeper, and delete the ledger data on corresponding bookies.
