I guess I should have elaborated to say that even if you're spinning up a new database expressly for this purpose (which I didn't see specifically called out in your docs anywhere as a best practice), you're starting off on the wrong foot. Maybe I'm old-school, but relational databases should be for relational data. This data isn't relational, it's write-once log data, and it belongs in files on disk, or in purpose-built analytics tools, if it gets too large to manage.
