Note that on-heap will have copies of entries, everything that is on-heap is stored off-heap as well. Off-heap is the primary storage, it holds all the in-memory data. It is controlled by memory policies. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Re-Re-TcpCommunicationSpi-Caught-unhandled-exception-in-NIO-worker-thread-restart-the-node-java-lange-tp15242p15253.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
