Data caching policy in multiple tenant enterprise resource planning system

摘要

A cache manager application provides a data caching policy in a multiple tenant enterprise resource planning (ERP) system. The cache manager application manages multiple tenant caches in a single process. The application applies the caching policy. The caching policy optimizes system performance compared to local cache optimization. As a result, tenants with high cache consumption receive a larger portion of caching resources.
