Abstract
In an embodiment, a computer-implemented method detects updates to a domain name system record system. In the method, a stream of data points is received with each data point describing a record of a domain name system. For respective data points, a processor is selected from a plurality of processors. The processors are each configured to apply a data point against a common filter that assesses whether the data point is in a set. At the selected processor, the respective data point is applied to the common filter to determine whether the record is included in the set. When the record is determined not to be included in the set, a message is provided to indicate that the domain name system includes a new record, and the common filter is updated to include the data point in the set.
