Method Summary
`int`	`getBulkFills()` The number of times the bulk buffer filled up, forcing the buffer content to be sent.
`int`	`getBulkOverflows()` The number of times a record was bigger than the entire bulk buffer, and therefore had to be sent as a singleton.

`int`	`getBulkTransfers()` The number of bulk buffers transferred (via a call to the application's `ReplicationTransport.send(com.sleepycat.db.Environment, com.sleepycat.db.DatabaseEntry, com.sleepycat.db.DatabaseEntry, com.sleepycat.db.LogSequenceNumber, int, boolean, boolean, boolean, boolean)` method).
