Storage Architecture Mermaid

The [mermaid] macro is a standalone macro and it cannot be used inline. Click on this message for details.
This macro generates standalone content. As a consequence you need to make sure to use a syntax that separates your macro from the content before and after it so that it's on a line by itself. For example in XWiki Syntax 2.0+ this means having 2 newline characters (a.k.a line breaks) separating your macro from the content before and after it. Simplified Storage - PostgreSQL as single primary database for all core data (claims, evidence, sources, users, metrics). Redis for caching, S3 for archives. Elasticsearch and TimescaleDB are optional additions only if performance metrics prove necessary. Start with 3 systems, not 5.
