Abstract: Techniques are disclosed for detecting risk via a server system that receives, based on user activity at a device, an indication of a trigger event corresponding to a potential electronic communication. After receiving the trigger event indication and prior to receiving an indication of initiation of the electronic communication, the system executes a set of computations for the communication, including performing a multi-hop query to a graph database storing a graphical representation of a plurality of communications and storing results of the execution. In response to initiation of the electronic communication, the system retrieves, using information corresponding to entities involved in the electronic communication, one or more portions of the results of executing the set of computations the database. The system determines, based on the retrieved results, whether to approve the electronic communication.

Abstract: A log is identified which includes one or more transactions to a source database. The log is ingested using a processor included in a storage processor complex, where the storage processor complex includes storage and a processor associated with the storage. The ingested information is transformed into change data appropriate for a target database stored at least in part on the storage processor complex. The change data is applied to the target database.
