instance method
checkout
Ruby on Rails 4.2.9
Signature
checkout()Check-out a database connection from the pool, indicating that you want to use it. You should call #checkin when you no longer need this.
This is done by either returning and leasing existing connection, or by creating a new connection and leasing it.
If all connections are leased and the pool is at capacity (meaning the number of currently leased connections is greater than or equal to the size limit set), an ActiveRecord::ConnectionTimeoutError exception will be raised.
Returns: an AbstractAdapter object.
Raises:
-
ConnectionTimeoutError: no connection can be obtained from the pool.
