Types ¶
type DB ¶
type DB struct {
// contains filtered or unexported fields
}
DB is a logical database with multiple underlying physical databases forming a single master multiple slaves topology. Reads and writes are automatically directed to the correct physical db.
func NewMySQLDB ¶
NewMySQLDB create the mysql master/slaves cluster
func (*DB) Ping ¶
Ping verifies if a connection to each physical database is still alive, establishing a connection if necessary.
func (*DB) SetMaxIdleConns ¶
SetMaxIdleConns sets the maximum number of connections in the idle connection pool for each underlying physical db. If MaxOpenConns is greater than 0 but less than the new MaxIdleConns then the new MaxIdleConns will be reduced to match the MaxOpenConns limit If n <= 0, no idle connections are retained.
func (*DB) SetMaxOpenConns ¶
SetMaxOpenConns sets the maximum number of open connections to each physical database. If MaxIdleConns is greater than 0 and the new MaxOpenConns is less than MaxIdleConns, then MaxIdleConns will be reduced to match the new MaxOpenConns limit. If n <= 0, then there is no limit on the number of open connections. The default is 0 (unlimited).
type RedisDB ¶
type RedisDB struct {
// contains filtered or unexported fields
}
func NewRedisDB ¶
NewRedisDB create the redis connection
