Lazy-connecting to database is handled via Doctrine_Db wrapper. When using Doctrine_Db instead of PDO / Doctrine_Adapter, lazy-connecting
|
||
|
|
to database is being performed (that means Doctrine will only connect to database when needed). <br \><br \>This feature can be very useful
|
||
|
|
when using for example page caching, hence not actually needing a database connection on every request. Remember connecting to database is an expensive operation.
