Gets the timeout used when trying to establish a connection to the database at GPUdb initialization. The value is given in milliseconds and the default is 0. 0 indicates no retry will be done; instead, the user given URLs will be stored without farther discovery.
If multiple URLs are given by the user, then API will try all of them once before retrying or giving up. When this timeout is set to a non-zero value, and the first attempt failed, then the API will wait (sleep) for a certain amount of time and try again. Upon consecutive failures, the sleep amount will be doubled. So, before the first retry (i.e. the second attempt), the API will sleep for one minute. Before the second retry, the API will sleep for two minutes, the next sleep interval would be four minutes, and onward.
