Abstract
A computer-implemented method includes receiving, at a datastore having a plurality of records of a transaction-monitoring system, a first record representing a first instance of a transaction. The datastore includes a first layer and a second layer. A first record hash code, based on the first record, is compared to a template hash code set that includes one or more template hash codes, where each template hash code corresponds to a respective transaction in a set of one or more known transactions. The first record is inserted into the first layer of the datastore. The first record is inserted into the second layer of the datastore, based at least in part on the first record hash code not being found in the template hash code set.
