• In memory Confluence Cache (default/preferred) supports cluster (MUST)
• File System (/path/to/cache/directory). Is the max files per directory limit a problem? No cleanup of outdated files. Cache directory inside $confluence.home or configurable (admin section of the plugin) (MUST)
• External server (like plantuml.com). Either self hosted or external plantuml-server? no native graphviz installation required (OPTIONAL) but setup is more complex! (OPTIONAL)
