AlgorithmLoader load LoadBalanceAlgorithm by loadBalanceType.

NewActualDataSource create an actual datasource through dsn.

NewClusterDataSource create a clusterDataSource by yaml clusterConfiguration and remote etcd clusterConfiguration, and listen remote activeKey, when remote activeKey changes, change the clusterDataSource's active node.

@param nodeName: node datasource name @param loadBalanceType: random or round-robin @param masterName: master datasource name @param slavesName: salves datasources name.

DsnFmt mysql dsn Example: username:password@protocol(address)/dbname?param=value, see details https://github.com/go-sql-driver/mysql#dsn-data-source-name.

ActualDataSource an actual datasource which contains actual dsn.

ClusterDataSource which have auto change target datasource capabilities.

NodeDataSource have read/write separation and failure retry capabilities.

RandomLoadBalanceAlgorithm get actualDataSource from salves randomly.

RoundRobinLoadBalanceAlgorithm get actualDataSource from salves in order.

DataSource interface.

LoadBalanceAlgorithm Read/write separation load balance algorithm interface.
