8. The non-transitory computer-readable storage medium of claim 7 , further comprising instructions that cause the one or more computer systems to initialize the state of the one or more stateful query operators by constructing a list of tuples for the one or more identified query operators from the result set of data records.
7. A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed by one or more computer systems, configure the one or more computer systems to perform at least: instructions that cause the one or more computer systems to receive a continuous query, the continuous query identifying an archived view, the archived view identifying a join query between-at least a first archived relation and a second archived relation associated with an application, the first archived relation comprising at least a first portion of historical data and incoming events related to an event stream of the application and the second archived relation comprising at least a second portion of the historical data and the incoming events related to the event stream; instructions that cause the one or more computer systems to identify a view root operator in the archived view, the view root operator being identified as a join operator in the join query identified in the archived view; instructions that cause the one or more processors to determine that a set of one or more operators in a query plan for the continuous query comprises one or more query operators, the one or more query operators being identified as stateful query operators of the query plan that maintain state information related to the application; instructions that cause the one or more computer systems to identify one or more of the stateful query operators in the query plan that topologically precede the view root operator; instructions that cause the one or more computer systems to construct a set of one or more archiver queries corresponding to the one or more stateful query operators that topologically precede the view root operator; instructions that cause the one or more computer systems to combine the set of one or more archiver queries to generate a combined archiver query; instructions that cause the one or more computer systems to execute the combined archiver query to obtain a result set of data records related to the application; instructions that cause the one or more computer systems to convert the result set of data records into a list of tuples for each of the one or more stateful query operators by: determining a value of an ordering attribute in the combined archiver query, the value of the ordering attribute corresponding to a number of the one or more stateful query operators in the query plan; and constructing the list of tuples for each of the one or more stateful query operators based at least in part on the value of the ordering attribute; instructions that cause the one or more computer systems to initialize a state of the one or more stateful query operators based at least in part on the list of tuples; and instructions that cause the one or more computer systems to generate a snapshot output of one or more data values related to the application based at least in part on the state of the one or more stateful query operators.
