    }
Construct service which will process notification requests in batch.
After each request batch will wait <code>waitTimeInSec</code> for more request to come
before executing but not more than <code>maxWaitTimeInSec</code>

Note: It is not recommended to use pooled connection

@param waitTimeInSec
           time to wait for more notification request before executing
           batch
@param maxWaitTimeInSec
           maximum wait time for batch before executing
