Class RecoverFatal

java.lang.Object
  bamboo.db.RecoverFatal

public class RecoverFatal
extends Object

An asynchronous interface to BerkeleyDB.

Data is stored on disk in a table with the following fields:

Bytes	Data
0-7	put time since the epoch (microseconds)
8-11	ttl interval after put time (seconds)
12-31	guid
32-51	data hash
52	whether this is a put (1) or remove (0)
53-	data

The data hash is needed to guarentee a consistent scan order and for removes. The primary key is bytes 0-52, and the secondary key is the guid concatenated with the data hash.
