Abstract
An event processing system for processing events in an event stream is disclosed. The system can execute instructions to receive a micro-batch stream of input events, process the input events using the CQL engine to generate a set of output events, generate, using a snapshot management algorithm implemented by the CQL engine, a snapshot of a current state of a system based at least in part on the set of output events related to the application, generate a first directory structure to access snapshot information associated with the snapshot of the current state of the system, generate a second directory structure to generate a list of snapshots associated with the current state of the system, and determine based at least in part on the snapshot management algorithm, a process to get, add, or clean the list of snapshots associated with the current state of the system.
