Are large casts problematic?

Hi,

Just had some media added to Emby that has an exorbitant amount of people listed under cast. 750+ were added to one item.

My Emby server also got hung around this time.

I'm worried that future metadata refreshes might also be a problem with this. I imagine adding that many to the DB at once could have choked the I/O.

Once they're in the database, should I care about this? Or is it worthwhile for me to edit metadata and lock the item? Would this actually clean up the db, or would the people added still exist there?

Thanks for any advice.
