Examples of BookKeeper

org.apache.bookkeeper.client.BookKeeper
BookKeeper client. We assume there is one single writer to a ledger at any time. There are four possible operations: start a new ledger, write to a ledger, read from a ledger and delete a ledger. The exceptions resulting from synchronous calls and error code resulting from asynchronous calls can be found in the class {@link BKException}.
