Detailed Description

Manages a connection pool, using a Redis Sentinel to get instaces ip, managing also failover.

Member Function Documentation

static ptr_t redis3m::connection_pool::create	(	const std::string &	sentinel_host,
		const std::string &	master_name,
		unsigned int	sentinel_port = `26379`
	)

inlinestatic

Create a new connection_pool.

Parameters

sentinel_host	Can be a single host or a list separate by commas, if an host has multiple IPs, connection_pool tries all of them
master_name	Master to lookup
sentinel_port	Sentinel port, default 26379

Returns

connection::ptr_t connection_pool::get ( connection::role_t type = connection::MASTER )

Ask for a connection.

Parameters

type	Specify the type required, Master, Slave or Any

Returns: a valid connection object

void connection_pool::put ( connection::ptr_t conn )

Put a connection again on pool for reuse, pay attention to insert only connection created from the same pool. Otherwise unpexpected behaviours can happen.

Parameters

conn

template<typename Ret >

Ret redis3m::connection_pool::run_with_connection	(	boost::function< Ret(connection::ptr_t)>	f,
		connection::role_t	conn_type = `connection::MASTER`,
		unsigned int	retries = `5`
	)

inline

Execute a block of code passing a connection::ptr_t if something fails, like broken connection, it will automatically retry with an another one.

Parameters

f	function to run, C++11 lambdas are perfect
conn_type	type of connection required
retries	how much retries do

Returns

void redis3m::connection_pool::set_database ( unsigned int value )

inline

Set a database to use on every new connection object created by the pool.

Parameters

value A valid database index
