Introduction to the Client API

BookKeeper Client API entry point is the org.apache.bookkeeper.client.BookKeeper class.

Usually a Client creates an instance of BookKeeper  and uses it to manage several Ledgers using the LedgerHandle API.

try (BookKeeper bookkeeper = BookKeeper.forConfig(new ClientConfiguration()).build();

           LedgerHandle ledger = bookkeeper.createLedger(BookKeeper.DigestType.CRC32, "foo".getBytes())) {

           ledger.addEntry("bar".getBytes());

}

In order to create a BookKeeper client you have to setup a ClientConfiguration object.

The most important parameter is the ZooKeeper connection string, which is needed to access to the BookKeeper ensemble.
