Abstract
An event deduplication system may efficiently perform event deduplication (identifying 'new' or “unique” events that might be an anomaly) by using a first stage that has multiple first stage processes running in parallel (e.g., at different data centers) and a single second stage that has a second stage process that receives and processes events from the different first stage processes. The second stage process updates a global state (e.g., lookup table) and periodically publishes the global state to the first stage processes to update their local state. When the second stage process receives a possible new event from a first stage process, it may more accurately determine whether the event is actually a new event based on the global state.
