The existing renewal process is too slow. However, having a batch perform one operation at a time has also proven problematic. The suggested design is to have a batch process renewals and when it has accrued a designated number of successful renewals, submit them to the storage module as a sub-batch.
The business logic can perform a pre-process where it checks to see if any of the renewals would fail for business logic reasons. Hold all renewals that pass the business logic test and then when the sub-batch size is reached make a request to the storage module using the sub-batch. This is potentially problematic in that if something fails in the sub-batch the entire sub-batch might be considered a failure. If this is undesired then a sub-batch size of 1 must be used. The size of the sub-batch will need to be determined, and could be configurable or a property specified in the request if desired. This approach would require a bulk update endpoint to be available from the storage module.

The "error" represents technical failures, such as an SQL failure.
