Abstract: Methods, systems, and computer-readable media for implementing event-stream searching using compiled rule patterns are disclosed. A rule base is compiled based at least in part on one or more rule patterns. The field names are sorted within the rule patterns. The rule patterns comprise one or more field names and one or more field values. The rule base represents a finite-state machine comprising a plurality of states. A plurality of events are received. The events comprise field names and field values describing events associated with resources in a provider network. The field names are sorted within the events. The rule patterns are evaluated against the events using the rule base. In determining a matched rule pattern for one of the events, the finite-state machine transitions between at least two of the states for the matched rule pattern.

Abstract: Methods, systems, and computer-readable media for generating message envelopes for heterogeneous events are disclosed. A plurality of events are received. The events are associated with computing resources in a multi-tenant environment. The events comprise an event formatted using a content schema and a different event formatted using a different content schema. A message is generated comprising a message envelope and the event. The message envelope comprises a plurality of field names and one or more field values formatted using an envelope schema. A different message is generated comprising a different message envelope and the different event. The different message envelope comprises the field names and one or more different field values formatted using the envelope schema. The message is filtered based at least in part on the message envelope, and the different message is filtered based at least in part on the different message envelope.

Abstract: Methods, systems, and computer-readable media for implementing freshness-sensitive message delivery are disclosed. A stream of events including an earlier event and a later event is received. A first attempt is performed to deliver a message indicative of the earlier event. The first attempt to deliver the message is unsuccessful. One or more additional attempts are scheduled to deliver the message indicative of the earlier event. The additional attempts are scheduled over a period of time following the first attempt. An attempt is performed to deliver an additional message indicative of the later event. The attempt to deliver the additional message is not delayed by the additional attempts to deliver the message.
