Ignite Nodes 在一段时间后断开连接

Question

大家好，我的集群遇到了问题。

每当点燃节点空闲时，它们就会断开连接，在那之后，如果我尝试连接，我的第一个请求就会失败。但是在第一次请求之后，所有请求都会成功，直到它们空闲一段时间。

请帮忙

Answer 1

您不应无限期地保留原始 JDBC 连接，而应使用适当的连接池，例如 c3p0，支持连接回收等。

Answer 2

好吧，这与 DataSource 无关，但将空闲连接超时设置为最大对我有用。

TcpCommunicationSpi spi = new TcpCommunicationSpi();

    spi.setUsePairedConnections(true);
    spi.setIdleConnectionTimeout(999999999999999999l);

    cfg.setCommunicationSpi(spi);
