This disclosure describes techniques implemented partly by a service provider network for distributed storage of event data in data storage according to a data-storage schema in order to reduce the amount of computing resources required to store and access the event data. The techniques may include generating event identifiers (IDs) for actions performed by users to manage cloud-based services. Rather than indexing event IDs by writing the event IDs to a database, the techniques described herein include storing event IDs in different file folders in storage according to a storage schema where the different file folders are assigned to store event IDs having different prefix portions. In this way, event IDs may be stored, or grouped, in different file folders according to prefix portions of the event IDs to reduce the amount of reads and writes required for the event IDs.
