A hello world example for pastry. This is the distributed driver.
|
|
|
|
For example, run with default arguments on two machines, both with args
|
|
-bootstrap firstmachine. Read the messages and follow the protocols.
|
|
|
|
Either separately or with the above, try -nodes 3 and -nodes 20. Try -msgs
|
|
100. Try the two machine configuration, kill it, restart, and watch it join
|
|
as a different node. Do that a few times, watch LeafSet entries accumulate,
|
|
then in 30 seconds, watch the maintenance take over.
