Correct, this is what is expected.
You need to
1) enable gravitation explicitly if you want to pull data out of a potential
backup scenario (this is necessary as a separate option to prevent calls trying
to gravitate data for data that does not exist. E.g., If I try
| String[] s = {"/one", "/two", "/three", "/four", "/five",
| "/six", "/seven", "/eight", "/nine", "/ten"};
|
| for (String fqn : s) cache[1].get(fqn);
|
I don't want expensive network calls (esp. if the cluster is big) to go out
when looking for nodes four to ten.
This is why when you know about a view-change event (perhaps by using a
listener) you can execute gravitate calls.
2) Gravitation should not happen automatically - only when a gravitation call
occurs, and even then, only for the node being called. This is to prevent a
"network storm" when a node dies. Let's assume each node has 1GB of data. If
a node dies, I don't want 1GB of network traffic of data being gravitated,
since this may then kill other nodes or cause the network to be unresponsive.
This is why this happens lazily, when a node is requested.
Hope this helps,
Manik
