1. A computer-implemented method, comprising: receiving, by a computer system configured to execute computer-executable instructions, a continuous query, the continuous query being identified based at least in part on an archived relation associated with an application; generating a physical query plan for the continuous query; identifying a set of one or more query operators in the physical query plan; constructing a set of one or more archiver queries corresponding to the set of one or more identified query operators based at least in part on the identifying; combining the set of one or more archiver queries to generate a combined archiver query; executing the combined archiver query to obtain a result set of data records related to the application; initializing a state of the one or more identified query operators based at least in part on the result set of data records, the initializing comprising constructing a list of tuples for the one or more identified query operators from the result set of data records; generating 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 identified query operators; and processing incoming real-time events related to the application based at least in part on the snapshot output of the one or more data values.
