12. The system of claim 11 , wherein the central processing unit is further configured to execute the plurality of instructions to at least: traverse the query plan in topological order to identify the view root operator, the view root operator being identified by an output operator configured to store event information related to the application; insert a buffer operator between the view root operator and the output operator in the query plan; and store the event information from the view root operator in the buffer operator.
11. A system, comprising: a memory storing a plurality of instructions; and a central processing unit configured to access the memory, wherein the central processing unit is further configured to execute the plurality of instructions to at least: 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; generate a query plan for the continuous query; 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; determine that a set of one or more operators in the query plan comprises one or more query operators, the one or more query operators being identified as stateful query operators of the query plan maintain state information related to the application; identify one or more of the stateful query operators in the query plan that topologically precede the view root operator; 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; combine the set of one or more archiver queries to generate a combined archiver query; execute the combined archiver query to obtain a result set of data records related to the application; 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; initialize a state of the one or more stateful query operators based at least in part on the list of tuples; and 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.
