HI, we have export functionality which reads the ignite data (around 1L records) and add to file.
i have implemented using jdbc driver to get the fetch size of 100. when i run parallel exports , client is getting restarted with following log 2017-05-15 22:36:50 342 ERROR TcpDiscoverySpi:495 - Failed to send message: TcpDiscoveryClientHeartbeatMessage [super=TcpDiscoveryAbstractMessage [sndNodeId=null, id=6e6089f0c51-17f17130-b771-42d2-88d6-3be03fda1389, verifierNodeId=null, topVer=0, pendingIdx=0, failedNodes=null, isClient=true]] java.net.SocketException: Socket is closed at java.net.Socket.getSendBufferSize(Socket.java:1215) at org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi.socketStream(TcpDiscoverySpi.java:1254) at org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi.writeToSocket(TcpDiscoverySpi.java:1366) at org.apache.ignite.spi.discovery.tcp.ClientImpl$SocketWriter.body(ClientImpl.java:1095) at org.apache.ignite.spi.IgniteSpiThread.run(IgniteSpiThread.java:62) 2017-05-15 22:37:04 903 WARN TcpDiscoverySpi:480 - Client node was reconnected after it was already considered failed by the server topology (this could happen after all servers restarted or due to a long network outage between the client and servers).

Is there any better way of implementing export like feature using ignite ? Please advise. Thanks. Thanks.
