Data source introspection takes a very long time

I have configured a data source to my local MariaDB testing environment, and have selected a couple schemas (databases) to synchronize. The introspection takes up to an hour to complete. It doesn't hang or anything, but it's kind of distracting to watch the progress spinner at the bottom of the screen for an hour every time I want to update the schemas. Is it taking this long for everyone, or is something wrong on my end?

I'm using it mostly for autocomplete when writing SQL, so if there is an alternative way to effectively keep autocomplete up to date with the current database schema, I'd like to know!
