Yes, sorry. The test works correctly: tx started on grid0 does not affect cache1, because they are on different nodes. Thus the operation cache1.put(1, 1111) is successfully committed.
Still I would not recommend to rely on any of observed behaviors here, because Ignite was not designed for mixing caches and transactions from different nodes in the same code. This behavior is undefined, untested and may freely change at any time.
