Hello! I think you could use ContinuousQuery <https://apacheignite.readme.io/docs/continuous-queries> (with initial query) to copy all data from cache in one cluster to cache in another cluster. It will also take care of the situation where cache on node1 is changed while it is being copied. If that is not a concern, a simple ScanQuery <https://apacheignite.readme.io/docs/cache-queries#scan-queries> will do.
As for signalling client when it is appropriate to read cache from node2, you could use CountDownLatch. Just always await() it in client, and on server countDown() it once all data is copied.
