Abstract
Systems and methods for managing cached information maintained in a distributed storage system are provided. Requests for information within the distributed storage system are directed to specific coordinators. Each coordinator can maintain cached version of information maintained at various information sources within the distributed storage system. To manage the cache, the system can utilize generation identifiers that identify the component within the distributed storage system that last updated information sources. Each coordinator can determine whether cached version of information is valid based on an analysis of generation identifiers.
