NodeStore
The properties
passed to this methods are associated with the
checkpoint and can be retrieved through the NodeStore.checkpointInfo(String)
method. Its semantics is entirely application specific.

NodeStore
This method is a shortcut for NodeStore.checkpoint(long, Map)
passing
an empty map for its 2nd argument.

NodeStore
Iterable
provides a
snapshot of valid checkpoints at the time this method is called. That
is, the Iterable
will not reflect checkpoints created after this
method was called.
See NodeStore.checkpoint(long, Map)
for a definition of a valid
checkpoint.
