ABSTRACT:
A method and system are provided for processing records from a set of records, where records are repeatedly being added to the set of records, and where each record in the set of records has to be processed once for each of a plurality of entities. According to the method, each record that is added to the set of records is marked with a default batch value. For each entity of the plurality of entities, a batch of the records is processed by performing the steps of: reading a last batch value associated with the entity, processing the records in the set of records that are marked with batch values that are more recent than the last batch value associated with the entity, and updating the last batch value associated with the entity to a most recent batch value of the records processed for the entity. Between processing consecutive batches for an entity of the plurality of entities, the set of records are marked by performing the steps of: updating a batch counter value to reflect a more recent batch number; and marking all records in the set of records that have the default batch value with the batch counter value.
