The Cache Macro caches the rendered contents of the body of this macro. Very useful when using macros that might be slow to render content, but where it does not really need to be dynamically generated for each and every request. Specifically, this can improve performance for accessing dynamic data from SQL, Excel, Script and similar macros. Cache will be refreshed if the body of the macro changes or if attachments to this page have been added, removed, or have newer versions. The cache applies to all users that view the page. The cached content can optionally be indexed for Confluence search.
The Future macro renders the macro body in the background allowing the rest of the page content to display immediately. It is used to improve display performance when pages contain longer running rendering macros. This is an extension of an older, unsupported macro provided by Atlassian. Now fully supported and moving forward! The Future macro has been modernized, fixed, enhanced, and included with Cache for Confluence.
Upward compatible with old version - remember to uninstall or disable the old future add-on if you previously installed it
