                   ConnectionPool

I represent a pool of connections to a DB-API 2.0 compliant database.

You can pass keywords args cp_min and cp_max that will specify the size of the thread pool used to serve database requests (possibly this is deprecated - it does not work at the moment in any case).

Interact with the database.
  jellyFor(self, jellier)
(internal) (inherited from Referenceable)
  operation(self, callback, errback, *args, **kw)
  processUniqueID(self)
Return an ID which uniquely represents this object for this process. (inherited from Serializable)
  query(self, callback, errback, *args, **kw)
  remoteMessageReceived(self, broker, message, args, kw)
A remote message has been received. (inherited from Referenceable)

Method Details

__init__(self, dbapiName, *connargs, **connkw)
(Constructor)

See ConnectionPool.__doc__

interaction(self, interaction, callback, errback, *args, **kw) 

Interact with the database.

The callable object presented here will be executed in a pooled thread.
'callback' will be made in the main thread upon success and 'errback'
will be called upon failure.  If 'callback' is called, that means that
the transaction was committed; if 'errback', it was rolled back.  This
does not apply in databases which do not support transactions.

@param interaction: a callable object whose first argument is
    L{adbapi.Transaction}.
@param *args,**kw: additional arguments to be passed to 'interaction'
