Large views cache table 47GB (larger than the complete db)

Same issue here on a Drupal 9 site. views_data_export_object_cache table size gradually increased to 700MB, which is 70% of the database size and caused the client to hit the 1000MB ceiling on Siteground hosting.

In D7, there is a bug in the logic of views_data_export_garbage_collect(). It is calling views_data_export_view_clear() with an array of eids, but views_data_export_view_clear() only works for an individual eid.

Patch attached.

Seems like this is pretty critical tbh, if that's what's going on/is wrong.
