下面是Coordinator特有的参数 max_pool_size和min_pool_size 像连接池一样,Coordinator维护着Coordinator到Datanodes的连接。因为每个事务都可能被所有的Datanode参与,这个参数应该至少设置为当前Coordinator的max_connections*集群中Datanode的值。min_pool_size设置Co

The default value of max-thread-pool-size is 200. If it is set to a low value, you might see only those number of active connections to postgres. Alternatively, you could set the max-pool-size and steady-pool-size to the same value say 10 and print the physical connection toString in...
Please check if all nodes are running fine and also review max_connections and max_pool_size configuration parameters 分析过程 检查了网络、防火墙、max_connections、max_pool_size均没有问题。无意中发现data node的参数文件中gtm_host设置为rt67-1,好像哪里不对。于是在官网上查询对该参数的定义。

engine = create_engine('postgresql://username:password@host:port/database', pool_size=最大连接数, max_overflow=0, poolclass=NullPool) 在上述代码中,将username、password、host、port和database替换为实际的数据库连接信息,并将最大连接数替换为所需的最大连接数。
