Public Instance methods

all_connections()

Returns an array of the master connection and the read pool connections

current_read_connection()

Get the current read connection

pool_weight(connection)

Get the pool weight of a connection

random_read_connection()

Get a random read connection from the pool. If the connection is not active, it will attempt to reconnect to the database. If that fails, it will be removed from the pool for one minute.

suppress_read_connection(conn, expire)

Temporarily remove a connection from the read pool.

use_master_connection() {|if block_given?| ...}
