Database Slow Query, Unable to Load Episode, all Star Trek Series

I was reading this thread:

So my items are:
sqlite> select count() from media_streams;
221689
sqlite> select count(
) from media_items;
89897

What are the supporting sqlite databases, com.plexapp.dlna.db and com.plexapp.plugins.library.blobs.db?

I know it’s been asked before, but it would be very nice for the devs to have mariadb as an optional database.
