MySQL’s concurrency control is a limit on the total number of threads that can be active at once, across all queries.

Traffic Control limits concurrency and resource use according to configurable metadata like the username, remote address, or the contents of any sqlcommenter tags included in the query. So you can say things like “the batch processing role can’t run more than four queries at a time.” The finer granularity is key.

There's definitely a light mode for planetscale.com (the docs, the blog, the changelog, and the UI). Should work on both desktop and mobile. Make sure your browser is requesting light mode. The browser doesn't always follow your OS-level preferences.
